Description

自配置多模式通信终端 The self configuring multi-mode communications terminal

本发明一般涉及蜂窝电话通信的改进。 The present invention relates generally to improvements in cellular telephone communications. 更具体地讲,是涉及一种适应于其环境的通信终端,而不必要包含多个与其不同格式和协议相联系的不同标准的物理传输设施。 More particularly, it relates to a communication terminal adapted to its environment, without necessarily containing a plurality of different standards of different formats and protocols to its associated physical transmission facilities. 响应于所检测的指示有待使用的协议和格式的接收信号的特性的一种单一的硬件实现利用软件算法和数字处理自动地重新改变程序。 Hardware features of a single protocol and receiving a signal format in response to the detection of a pointer to be implemented by using software algorithms and digital processing program automatically re-changed.

无线通信的各种不兼容标准的激增,迫使许多用户购买和租用多个每个仅能按照一种特定标准工作的终端。 Various wireless communication standard is not compatible with the surge, forced many users to buy and rent a plurality of terminals each only operating according to a particular standard. 使用特定标准终端的问题对于国际移动通信用户来说是特别困难的,这些用户在不同的时间会遇到不同的系统。 The problem with using a specific standard for international mobile communication terminal users is particularly difficult, these users will encounter different systems at different times. 不知道在什么地方是比在蜂窝电话区域中有更为严重的问题,其中在世界的各个不同部分和甚至在各个不同的国家中,高级移动电话业务(AMPS)、次高级移动电话业务(NAMPS)、时分复用连接(TDMA)、全球移动通信系统(GSM)、码分多址连接(CDMA)和其他各种系统以不同的成功程度进行着竞争。 I do not know where there is a more serious problem than in the cellular phone area, which in various parts of the world and even in different countries, the Advanced Mobile Phone Service (AMPS), time Advanced Mobile Phone Service (NAMPS ), time division multiplexed connection (TDMA), global system for mobile (GSM), code division multiple access (CDMA), and various other systems compete with different degrees of success.

在蜂窝电话区域中某些系统具有对与早期系统反向兼容性的要求,使得新标准的移动终端必须也能够工作在使用较老标准的系统中。 In a cellular telephone system having a certain area on the backward compatibility with earlier systems requirements, such that the new standard mobile terminal must also be able to operate using the system of older standards. 这种“双模式”能力明显地描述在对于TDMA/AMPS移动通信系统的IS-136规范中。 Such "dual-mode" capability for explicitly described in TDMA / AMPS mobile communication system according to IS-136 specification. 在过去双模式的工作要求比实现任何一种标准需要更多的硬件。 Work in the past to achieve dual-mode requirements than any of the standard requires more hardware. 本发明描述了一种方法,使得多种工作模式可能利用少量硬件的或者不增加硬件来实现,和该方法使得工作模式自动地适应所接收信号的标准。 The present invention describes a method may be such that multiple modes of operation or with a small amount of hardware implemented without additional hardware, so that the working method and the mode is automatically adapted to the standard of the received signal.

在过去已经建议过双模式或多模式电话或无线电设备的操作。 It has been suggested in the past by operating a dual-mode or multi-mode phones or radio equipment. 例如,授予Durtler等人的美国专利No.5438682可以根据蜂窝电话用户的位置在模拟模式与TDMA模式之间变化。 For example, Grant et al., U.S. Patent No. Durtler No.5438682 may vary between analog mode and TDMA mode based on the location of the cellular telephone user. 但是,这种方法涉及蜂窝电话的容量并且专用硬件需要用于不同系统的不同标准。 However, this method relates to the capacity of the cellular telephone and the dedicated different criteria for the different systems require hardware.

还有授予Dent的美国专利No.5535432的工作在陆基蜂窝的蜂窝电话与在轨卫星系统之间转换的和涉及可以提供对于不同系统带宽的宽和窄的信道间隔的频率合成器的系统,该系统是能在各个系统之间进行转换的双模式蜂窝电话。 Also US Patent No.5535432 Dent work between the ground-based cellular and orbiting satellite cellular telephone systems and relates to the conversion of the frequency synthesizer may be provided for different system bandwidth wide and narrow channel spacing of the system, the system is capable of dual mode conversion between various cellular telephone systems. 但是,Dent的专利不适合于不同的标准,除非各种标准的参数已被存储在蜂窝电话中了。 However, Dent patents are not suitable for different standards, unless a variety of standard parameters have been stored in the cellular telephone. 此外,Dent的专利还要依靠实施两个天线和专用的硬件。 In addition, Dent relies on implementing two patents also antennas and dedicated hardware.

无需不同标准的每种格式和协议的专用硬件,便可以自动地转换不同标准的模式的蜂窝电话系统将会克服上述各个专利的不足。 Without different standard formats and protocols of each dedicated hardware, can be automatically converted to a different standard mode, the cellular telephone system will overcome the shortcomings of each of the above patents.

因此,本发明一个目的是允许一个终端能符合若干不同标准地进行操作,而不必须含有多个标准的专用硬件。 It is therefore an object of the present invention is to allow a terminal can meet a number of different standards to operate, must contain not more criteria dedicated hardware.

本发明的另一个目的是通过符合当前的和未来的的操作标准的范围,而又不必在任何时间中含有实现所有这些标准的软件,从而降低了终端的成本。 Another object of the present invention is achieved by a range of current and future compliance with the standard operation, without having to implement all these standards containing software at any time, thereby reducing the cost of the terminal.

本发明还有一个目的是允许该终端自身自动地适应其所被利用的网络或链路的操作特性。 Another object of the present invention is to allow the terminal to adapt itself automatically to the operational characteristics of the network or it is utilized links.

在主要的通信网中,存在着在一个方向上的信号的协议和在另外一个方向上信号的协议之间的直接对应关系。 In the main communication network, there is a direct correspondence between the protocol of the protocol in a direction signal and a signal in the other direction. 在大多数情况下,如果从信号特性可以确定接收的信号的标准管理协议的话,则用于呼叫建立和拆除和其他监视和控制功能也可以被推演出来。 In most cases, if the signal characteristics from the standard management protocol of the received signal can be determined, then for call setup and teardown and other monitor and control functions can also be deduced. 仅仅在接收终端中需要少量的核心功能软件就能识别出该标准。 In the receiving terminal only needs a small amount of core functionality software can recognize the standard.

本发明采取这种核心功能的有限范围,加上利用基于数字处理的设计可能作出信号的智能处理和分析,利用少量的硬件和软件来实现标准的识别。 The present invention takes this core function of a limited range, together with the use of intelligent processing and analysis of signals could make digital processing based design, using a small number of hardware and software to achieve standard identification. 一旦标准被识别,则所有要求的终端功能和操作参数都可以知道和可以实现适当的可执行码。 Once the standard is identified, the terminal function and operation of all required parameters are known and can achieve the appropriate executable code. 由于多数功能是由软件或者软件组成的硬件实现的,则终端可以自行配置来在这种模式些进行操作,而无须按硬件实现的各种终端类型的大量增加,和也无须用户介入。 Since most of the functions are hardware or software components of the software implementation, the terminal can configure itself to operate in this mode some, without pressing a significant increase of the various terminal types implemented in hardware, and also without user intervention.

软件实现的功能的大量使用减少了在终端中所须的物理部件的数量和使可能增强通信链路的性能和可靠性。 Heavy use of software implementation of functions reduces the physical components in the terminal and so as to be possible to enhance the number of performance and reliability of the communication link. 核心功能软件还使得其可能“下载”用于各种当前的和未来的标准的适当可执行码,而不要求在终端中的物理改变。 Core functionality software also makes it possible to "download" for a variety of current and future standards appropriate executable code, without requiring physical changes in the terminal. 这种特点可以被用于限制在数字处理电路的非易失存储器中本机所带有的软件码的数量。 This feature may be carried by the unit number of the software code in the nonvolatile memory in the digital processing circuit for limiting. 软件实现配置终端可以到这样一种程度,即它可以发送对适合的标准的下载请求,和对于非本地带有的适当的可执行码接收下载。 Software configuration of the terminal may be to such an extent that it may send a download request for the appropriate standard, and receive the download for the proper executable code with the non-local. 这种特点在许多通信链路协议的系统中都是可用的是一个显著的优点,但需要具有一种固定的公知格式和协议的控制信道。 This system features a number of communication links are available protocols is a significant advantage, but requires a control channel having a fixed known formats and protocols.

对于本专业的技术人员来说通过下面的优选实施例的描述和各个附图其他各个目的、特点和优点将是显而易见的。 Figures described and various other objects, features and advantages of the person skilled in the art from the following embodiments will be apparent from preferred.

参照图1,表示出本发明的概括框图。 Referring to FIG 1, a generalized block diagram of the present invention is shown. 图1表示一个通信终端系统中的不同的部件。 1 shows a communication terminal of a different system components. 在图中,通信终端表示为包括6个主要功能:天线100、射频(RF)部分101(见图2的实施例)、射频接口102(见图3的实施例)、数字处理部分103、用户接口104和电源部分105。 In the drawing, the communication terminal is represented as including six main functions: antenna 100, a radio frequency (RF) section 101 (see Example 2), the RF interface 102 (see Example 3), the digital processing section 103, the user interface 104 and a power supply section 105.

该终端通过经由天线100分别进行辐射和进行接收,发射已调制射频载波和接收已调制射频载波与其他各终端和各通信节点进行通信。 By radiation and the terminal receives via the antenna 100, respectively, transmitting and receiving modulated radio frequency carrier modulated RF carrier to communicate with each terminal and each of the other communication nodes. RF部分101处理载波信号的发射和接收。 Transmitting and receiving section 101 processes the carrier signal RF. RF部分101产生被发射的载波和下变频和滤波所接收的载波为中频(IF)信号106。 RF Section 101 generates the transmitted carrier and downconverts and filters the received carrier to an intermediate frequency (IF) signal 106. 被发射的载波的调制是由调制信号107控制的,而载波的频率和功率是由RF控制总线108设置的。 The modulated carrier is transmitted by the modulation control signal 107, and the power and frequency of the carrier by the RF control bus 108 is provided. RF控制总线108还控制接收机的定时和在接收通路中的增益。 RF control bus 108 also controls the timing and gain of the receiver in the receive path.

射频接口102含有多个模拟到数字(“A/D”)、数字到模拟(“D/A”)变换器和数字控制寄存器。 Radio Interface 102 contains multiple Analog to Digital ( "A / D"), digital to analog ( "D / A") converter and digital control registers. IF信号106被这些A/D变换器之一数字化以便进一步被数字滤波和解调。 The IF signal 106 is one of these A / D converter is digitized for further digital filtering and demodulation. 数字化的信号经数字接口总线109被提供到数字处理部分103。 The digitized signal via a digital interface bus 109 is supplied to the digital processing section 103. 基于来自数字处理部分103的数字输入利用D/A变换器产生在RF控制总线108上的调制信号107和模拟信号。 Generate a modulated signal on the input RF control bus 108 and analog signals 107 the D / A converter based on the digital processing from the digital section 103. 射频接口102中的数字控制寄存器提供附加的用于RF控制总线108的数字控制信号,而来自RF部分101的模拟监视信号被在射频接口102中的附加的A/D变换器变换成数字值。 The digital RF interface 102 provides additional control register for RF control bus 108 of the digital control signal, and the monitor signal from the RF analog section 101 is converted into an additional interface 102 in a radio frequency A / D converter into a digital value. 因此,射频接口102用作RF部分101的基本上模拟电路与数字处理部分103的数字处理和控制功能之间的一种信号格式变换接口。 Therefore, the RF interface 102 is substantially as RF analog circuits and digital processing section 101. A signal format between the digital processing and control functions of the interface section 103 is converted. 射频接口102容易地按照一个单个芯片来实现,且甚至可以集成为包含数字处理部分103和用户接口104的主要部分的一个较大的芯片。 Radio Interface 102 is easily implemented in accordance with a single chip, and even may be integrated into a digital processing comprise a large portion of the chip main portion 103 and a user interface 104.

发射和接收信号的大多数标准专门处理都发生在数字处理部分103中。 Most standard signal transmitting and receiving special processing occurs in the digital processing section 103. 这种处理完全是数字的和经由软件算法执行的。 This process is entirely digital and via software algorithms executed. 因此很容易修改操作模式和操作参数。 Thus it is easy to modify the operating mode and operating parameters. 这种修改必须简单地选择用于数字处理功能的不同的可执行码。 Such modifications must simply selecting a different executable code for the digital processing function. 如果可以识别接收信号的格式和对应的所选择的可执行码,则可以很容易地适应各种符号速率、数据格式和调制类型。 If the format can be identified and the corresponding executable code to the selected received signal, can be easily adapted to a variety of symbol rates, data formats and modulation types. 在许多系统中,如果接收的协议可以被识别,则也可以识别正确的发送协议。 In many systems, if the received protocol can be identified, it is also possible to identify the correct transmission protocol. 数字处理电路通过比较所接收的信号特性与存储在非易失性存储器中的至少一组信号特性来识别接收信号的标准。 Digital processing circuit by comparing the received signal characteristics stored in the nonvolatile memory at least one set of signal characteristics to identify the standard of the received signal. 在另外一些实施例中,终端可能必须选择码,以便正确地滤波、解调和全面解码所接收的信号,从而获得关于正确发射载波频率、协议和带宽的信息。 In other embodiments, the terminal may have to select code to correctly filter, demodulate and fully decode the received signal to obtain information about the carrier frequency, protocol and bandwidth correct transmission. 在任何一种情况下,在接收处理中仅需要少量的公共核心功能,就能识别接收载波的通信标准。 In either case, the receiving process requires only a small common core functionality, can identify the communication standard of the received carrier.

用户接口104至少含有下列部件,和可以的附加的一些项目:键盘(或电键盘)、字母数字(或CRT)显示器、LED、扬声器、麦克风、音调传感器。 The user interface 104 contains at least the following components, and possible additional items: a keyboard (or electric keyboard), alphanumeric (or CRT) display, LED, speaker, microphone, tone transducer. 用户接口104还含有接口这些部件到数字处理部分103的电子电路。 The user interface 104 further comprises an electronic circuit components to the digital interface to the processing portion 103. 用户接口104一般包括A/D和D/A变换器、增益控制放大器、LED驱动器和显示器驱动器。 The user interface 104 typically includes A / D and D / A converters, gain controlled amplifiers, LED drivers and a display driver. 在本发明的示例实施例中,用户接口104是蜂窝移动通信的手机,用户接口104含有所有这些部件。 In an exemplary embodiment of the present invention, user interface 104 is a mobile phone of a cellular mobile communication, a user interface 104 containing all of these components.

电源部分105含有可能是一个电池的功率电源。 Power supply section 105 may contain a battery power supply. 它还包含一个或多个DC到DC的变换器,产生规定的等于额定功率电源的电压和/或高于或者低于这个电压的电压。 It also contains one or more DC to DC converter, to produce a predetermined nominal power supply voltage is equal to and / or above or below this voltage. 此外,包括一些电子开关,以响应来自用户接口104或者数字处理部分103的输入接通和关断各种输出电压。 In addition, some electronic switch comprising, in response to a variety of output voltages from the user interface 104 or a digital input processing section 103 on and off. 电源部分105输出提供电压到图1的方框部分101到104。 Power supply portion 105 outputs a voltage to a portion of FIG. 1 is a block 101-104.

参照图2,图中表示出图1的RF部分101的示例性实施例。 Referring to Figure 2, an exemplary embodiment of the RF section 101 of FIG. 1 shown in FIG. 这个实施例表示一种工作在1900MHz频段(工作在1900MHz的IS-137ATDMA和PCS-1900)的双模式蜂窝移动电话手机。 This embodiment shows a working band at 1900MHz (work in the IS-137ATDMA and 1900MHz PCS-1900) of dual-mode cellular mobile telephone handset. 虽然没有表示出对于AMPS/TDMA的800/1900MHz双频段功能的双模式特点,但通过增加适当的硬件到RF部分101中,如果加入相应的软件或下载的话,则该设备可以很好地工作在AMPS模式下。 Although not shown 800 / 1900MHz dual band dual mode function characteristics for AMPS / TDMA, but by adding the proper hardware into RF Section 101, if the corresponding software is added or downloaded, then the device may work well in AMPS mode.

在图2中,到达和来自天线的RF信号被表示为200。 In FIG. 2, the RF signal to and from the antenna 200 is denoted. 在这个导线上的RF能量由双工器201进行频段分割。 RF energy in this band division performed by the wire diplexer 201. 在1930MHz到1990MHz范围的频率具有从导线200到导线220的路径,而在1850MHz到1910MHz范围的频率具有从导线239到导线200的路径。 Frequency of 1930MHz to 1990MHz range from wire having a conductor path 200 to 220, in the frequency range from 1850MHz to 1910MHz has a path 239 to the lead wire 200. 在导线200上的接收信号在被施加到接收机带通滤波器(BPF)203前由低噪声放大器(LNA)202进行放大。 Received signal on lead 200 is applied to the receiver in a band pass filter (BPF) 203 is amplified by a low noise amplifier before (LNA) 202.

在该示例性实施例中,BPF203具有1960MHz的中心频率和+/-32MHz的带宽,它允许在标准137A和PCS-1900中分配给移动通信接收的频率通过该滤波器,但阻止双工器的输入端从导线239漏泄到在输出端的导线220的发射载波的任何残余通过。 In the exemplary embodiment, BPF 203 has a center frequency and a bandwidth of 1960MHz +/- 32MHz, which is assigned to the mobile communication allows the reception frequency by the filter 137A and PCS-1900 standard but prevents duplexer leakage from the input terminal to the wire 239 through any residual carrier is emitted at the output 220 of the wire. BPF203的输出经导线222传送到混频器204。 BPF203 output via lead 222 to mixer 204 transmits. 到混频器204的第二输入通过导线227并由主合成器208产生的载波信号组成。 To a second input of the mixer 204 is composed of a carrier signal by the main wire 227 generated by the synthesizer 208. 如果BPF205具有67.71MHz的中心频率,则在导线227上的信号具有在1997.75MHz到2057.75Mhz范围的频率。 If BPF205 has a center frequency of 67.71MHz, the signal on lead 227 has a frequency in the range 2057.75Mhz to 1997.75MHz.

混频器204的输出含有等于其两个输入频率的和与差的频段的信号。 The output of mixer 204 contains signals equal to the sum and difference of the two input frequency band. 差频段覆盖67.71MHz,该频段位于BPF205选择的这个频段中的一段,中心在67.71MHz。 Difference band covers 67.71 MHz, which band is located in this section BPF205 selected frequency band, the center 67.71MHz. 因为在导线227上的频率可以进行变化,在移动通信接收频段中的任何信道都可能出现在该滤波器的中心频率。 Since the frequency on lead 227 can be varied, any channel in the reception band of the mobile communications can occur at the center frequency of the filter.

BPF205具有180KHz的带宽,刚好足够通过PSC-1900的一个信道,但大大都宽于IS-137A TDMA所要求的信道。 BPF205 has a bandwidth of 180KHz, just enough through a channel of the PSC-1900, but are much wider than the IS-137A TDMA channel required. 对于IS-137ATDMA方式,高于所期望信道62dB的干扰信号在离在滤波器的带宽的中心的信道60KHz处呈现。 For IS-137ATDMA embodiment, the interference signal is higher than the desired channel are presented in 62dB from channel 60KHz bandwidth at the center of the filter. 期望信道则低于干扰电平62dB。 Desired channel interference level is less than 62dB. 这个事实在射频接口102的描述中将会涉及到。 This fact is described in the RF interface 102 will be involved.

BPF205的输出被自动增益控制放大器(AGC)206进行放大。 BPF205 is output automatic gain control amplifier (AGC) 206 amplifies. AGC206的增益受在导线226上的电压电平控制。 AGC206 gain controlled by the voltage level on conductor 226. 这个电压是保持在导线225上的峰-峰摆幅大体上恒定的的控制环的输出,该摆幅即使在导线224上的放大器输入可以有宽范围的信号振幅的情况下也保持恒定。 It is kept constant at the peak output swing of a substantially constant control loop, even if the swing amplifier input on lead 224 can have a wide range of signal amplitude situation - this is to keep the voltage on conductor 225 at peak. 该放大器在其整个80dB的增益控制范围的信号转移特性上保持良好的线性。 The amplifier remains good linearity in its signal transfer characteristics of the entire gain control range of 80dB. 导线225是从RF部分101到射频接口102的中频(IF)输出(见图1)。 Conductor 225 from an intermediate frequency (IF) RF section 101 to a radio frequency output interface 102 (see FIG. 1).

在导线227上的信号是由主合成器208产生的。 Signal on conductor 227 from the main synthesizer 208 is produced. 频率的调谐是通过经数字输入总线230的软件控制实现的。 The tuning frequency control input bus 230 is implemented digitally by software. 主合成器208是按10kHz步进可调谐的。 Main Synthesizer 208 is tuneable according to 10kHz step. 在TDMA模式下,它实际上是按30kHz步进调谐的,而PCS-1900模式下是按200kHz步进调谐的。 In the TDMA mode, it is actually tuned by stepping 30kHz, while the lower PCS-1900 mode is based on the 200kHz tuning step. 这些数据反映了在相应标准中的信道间隔。 These data reflect the channel spacing in the respective standards.

主合成器208的调谐精度是由在导线229上的频率基准的精度决定的。 Main Synthesizer 208 is tuned precision is determined by the accuracy of the frequency reference on lead 229 is. 这个精度在数字处理部分103中经由软件通过实现一个控制环可以做得非常高。 The accuracy of the digital processing section 103 via a control loop implemented by the software can be very high. 该控制环应用在导线228上的一个精密电压,使得压控晶体振荡器(VCXO)207产生精确的输出频率。 The control loop used in a precision voltage wire 228, such that the voltage controlled crystal oscillator (VCXO) 207 to produce an accurate output frequency.

主合成器208的输出还施加到混频器209,该混频器作为其另一个输入端具有来自频差合成器(Offset Synthesizer)210的信号。 The output of the main synthesizer 208 is also applied to mixer 209, the mixer has as its other input signal from Offset Synthesizer (Offset Synthesizer) 210 a. 频差合成器210产生在一个频率上的信号,该频率是当由混频器209从导线227上的信号频率减去该频率时,在导线232上产生一个正好是所发射的信道的频率的输出。 Offset Synthesizer 210 generates a signal on one frequency, this frequency when the frequency is subtracted from the frequency of the signal on lead 209 mixer 227 generates on lead 232 a frequency channel is exactly the emitted output. 混频器209是按一种单边带混频器实现的,显著地减少了混频器的在频率上等于两个输入频率之和的输出分量。 Mixer 209 is implemented by one kind of the single sideband mixer, reducing substantially the mixer is equal to the sum of the two input frequencies in the frequency component of the output. 在示例性实施例中,频差合成器210产生具有147.75MHz频率的信号。 In an exemplary embodiment, Offset Synthesizer 210 generates a signal having a frequency of 147.75MHz. 这使得当在导线227上的信号被调谐在1997.79MHz-2057.67MHz范围时,被发射的载波落入1850.04MHz-1909.92MHz范围。 This enables the signal on lead 227 is tuned 1997.79MHz-2057.67MHz range, the carrier is transmitted falls 1850.04MHz-1909.92MHz range. 对于偏移频率的147.75MHz的选择保证了没有这个信号的谐波落入1930到1990MHz的接收载波频段。 The choice of the offset frequency 147.75MHz ensures that the harmonic signal is not received carrier band falls within the 1990MHz to 1930. 对于双频段操作而言,当设备工作在800MHz频段时,频差合成器210被调谐到112.71MHz。 For dual band operation, when the device is in the operating band 800MHz, Offset Synthesizer 210 is tuned to 112.71MHz. 这再次将信号的谐波置于接收RF频段之外。 This again disposed outside the harmonic signals received RF band.

频差合成器210经混频器209被用于产生发射载波。 Offset Synthesizer 210 is used via the mixer 209 to produce transmission carrier. 一个合成器不能用于直接产生等于高功率发射载波的频率,因为这样将容易受到在载波上的调制的“牵引”。 A frequency synthesizer can not be used directly to generate a high power transmission is equal to the carrier, as this will readily be modulated on a carrier "pull." 这个问题通过利用固定的频差和混频器予以解决。 The problem to be addressed by the use of a fixed frequency difference and mixers.

混频器209的输出经导线232馈送到I/Q调制器211。 The output of mixer 209 is fed via lead 232 to I / Q modulator 211. 作为在其两个模拟基带输入导线233和234上的电压操作的结果,这个正交调制器可以产生在其输入导线232上的载波的调制的任何形式。 As a result of its two analog baseband input operating voltage on line 233 and 234, this quadrature modulator can produce any form of modulation of the carrier of its input on line 232. 取决于其基带输入的特性由I/Q调制器211产生按照137A标准,或按照PCS-1900的高斯最小频移键控(GMSK)的FM信号或正交相移键控(QPSK)信号。 Which depends on the characteristics of the input baseband I / Q modulator 211 is generated according to standard 137A, or minimum shift keying (GMSK) FM signal or quadrature phase shift keying (QPSK) signal in a Gaussian PCS-1900. 在射频接口102的描述期间,描述GMSK信号的产生。 During the description of the radio interface 102, described in GMSK signal generation.

I/Q调制器211的输出被馈送到电压增益放大器(VGA)212。 Output I / Q modulator 211 is fed to a voltage gain amplifier (VGA) 212. VGA 212的增益受在导线236上的电压的控制,该电压被进行调整,以设置发射载波的功率。 VGA 212 gain on line 236 by the control voltage, the voltage is adjusted to set the power of the transmitted carrier. VGA 212的输出被馈送到BPF 213,允许1850-1910MHz的信号通过,而阻止来自调制器211的2140-2200MHz信号的残余。 The output of VGA 212 is fed to BPF 213, allowing the signal 1850-1910MHz, 2140-2200MHz and prevents residual signal from the modulator 211. 该残余是由于混频器209的不良单边带特性造成的。 The residue is due to the poor characteristics of single-sideband mixer 209 caused.

在放大和滤波以后已调制发射载波被馈送到功率放大器214。 After amplification and filtering of the modulated carrier is fed to the transmitter power amplifier 214. 通过去掉经导线240到该功率放大器的馈电电压,实际发射的完全关闭得以实现。 240 to the supply voltage of the power amplifier by removing via a wire, the actual transmission is achieved fully closed. 当没有发射载波将被产生时,直流功率被去掉时,进一步利用降低VGA 212的增益到最小,通过功率放大器214漏信号的幅度被减至最小。 When there is no transmit carrier is to be generated, the DC power is removed, using a further reduced to a minimum VGA gain 212, is minimized by the amplitude of the leakage signal amplifier 214. 当通过给予直流电源电压进行启动时,功率放大器214馈送发射载波到双工器201,在双工器择径到达导线200和天线100。 When administered by the DC supply voltage to start, transmit carrier power amplifier 214 is fed to the duplexer 201, the duplexer 200 and the wire-routed antenna 100 reaches. 由于双工器201的频带分割特性的结果,非常小的发射载波出现在导线220上。 As a result of the divided band characteristics of the duplexer 201, very little of the transmit carrier appears on line 220. 因此这种硬件能够同时发射和接收,以及时间交错地实现有效地发射/接收。 Thus Such hardware can simultaneously transmit and receive, and time interleaving to achieve efficient transmit / receive.

参照图3,更为详细地表示出如图1的方框图所表示的射频接口102。 Referring to FIG. 3, FIG. 1 shows a block diagram of a radio frequency interface 102 represented in more detail. 来自射频部分101的模拟67.71MHz的IF信号通过导线225到达A/D变换器300。 The analog IF signal from the RF part 101 of 67.71MHz 225 reaches the A / D converter 300 via a wire. 这个10比特A/D变换器利用一个取样速率执行IF副取样,该取样速率在PCS-1900模式中是符号速率的8倍,在IS-137A TDMA模式中是符号速率的大约89.16倍。 The 10-bit A / D converter using a sampling rate Executive Vice IF sampling, the sampling rate is eight times the symbol rate in the PCS-1900 mode, is about 89.16 times the symbol rate of the IS-137A TDMA mode. 取样速率大约是2.1667MHz。 Sampling rate is about 2.1667MHz. 该取样速率还接近期望信道的IF频率被31.25除。 The sampling rate is also close to the desired IF frequency channels are in addition to 31.25. 这些数目的重要性下面要进行解释。 The importance of these numbers to be explained below.

A/D变换器300的输出是一个10比特字,经10比特并行总线320连接到数字复下变频器307。 The output of A / D converter 300 is a 10-bit word by 10-bit parallel bus 320 is connected to the digital complex down-converter 307. 设置在导线321上的取样脉冲提供A/D变换器300的输出控制。 Sampling pulse provided on lead 321 provides A / D converter 300 of the output control. 该取样脉冲速率大约是2.1667MHz。 The sampling pulse rate is approximately 2.1667 MHz. 数字信号处理电路的数字信号处理器调整取样信号的相位,以获得对于PCS-1900模式的最佳取样。 The digital signal processor of the digital signal processing circuit to adjust the phase of the sampling signal to obtain optimal sampling for the PCS-1900 mode. 在TDMA模式中,2.1667MHz取样被允许自由运行。 In the TDMA mode, 2.1667MHz sample was allowed to run free. 这种机制是由数字处理部分103执行的比特定时恢复算法的一部分。 This mechanism is the bit processing section 103 performed by the digital portion of the timing recovery algorithm.

A/D变换器的取样速率是2.1667MHz,而被取样IF的频带的中心是67.71MHz。 Sampling rate of A / D converter is 2.1667MHz, and the center of the band being sampled IF is 67.71MHz. IF频带为180KHz宽。 Wide IF band is 180KHz. 因为IF信号在远低于耐奎斯特速率下被取样,在被取样的信号中产生许多都是180MKHz宽的假频带。 Since the IF signal is sampled at a rate much lower than the Nyquist, it is 180MKHz produce many false wide band signal is sampled. 这些频带具有在等于IF载波频率+/-取样频率的N倍的各个频率点上的中心频率。 These bands have center frequencies in the respective frequency points equal to N times the carrier frequency + IF sampling frequency. 对于N=31的频带具有(67.71-31*2.1667)MHz,或者543.333KHz的中心频率。 N = 31 for a frequency band having a (67.71-31 * 2.1667) MHz, or the center frequency of 543.333KHz. 其他假信号具有高于1MHz的频率,和在下变换、滤波和抽样处理中,这些频率都被滤掉。 Other spurious signals having a frequency above 1MHz, the lower and conversion, filtering and decimation process, these frequencies are filtered out.

数字复下变换器307利用被4除的取样速率分别变换543.333KHz载波为基带I和Q信号322和323。 The down-converter 307 using a digital complex sample rate is divided by 4 543.333KHz carrier are converted into baseband I and Q signals 322 and 323. 被4除的取样速率是541.666KHz,该频率低于载波频率1.667KHz。 Sampling rate divided by 4 is 541.666KHz, the frequency is lower than the carrier frequency 1.667KHz. 因此,I和Q信号提供给具有1.667KHz载波相位旋转余量的抽选低通滤波器306,即使在由数字处理部分103进行取样定时调整的情况下。 Thus, I, and Q signals supplied to the decimation 1.667KHz having a carrier phase rotation remaining low-pass filter 306, even when the processing section 103 by the digital sampling timing adjustment. 这在数字处理部分103中以后校正。 After this correction processing section 103 in number. I和Q信号仍然具有2.1667MHz的取样速率,和对于TDMA模式它们含有来自多个接收信道的信号。 I and Q signals still have a sample rate of 2.1667MHz, and for the TDMA mode they contain signals from multiple received channels.

抽选(decimating)低通滤波器306的滤波特性可以被控制,以满足不同信号标准的要求。 Drawing (decimating) the low-pass filter characteristic 306 can be controlled to meet the requirements of different signal standards. 在本发明的示例性实施例中,该抽选低通滤波器306具有两组内置的系数:一组满足PCS-1900模式的工作,和另一组满足IS-137A的TDMA模式。 In an exemplary embodiment of the present invention, the decimating low pass filter 306 having a built-in two coefficients: one group satisfies the PCS-1900 mode of operation, and the other group satisfies the IS-137A TDMA mode. 这些是通过检测在导线324上的除以4的取样速率自动进行选择的。 These are selected by dividing the sampling rate detector 324 on line 4 automatically. 在另外一些实施例中,为全数字实现的抽选低通滤波器306可以具有其按照实现各种滤波特性宽度范围的需要从数字处理部分103装入的各个参数。 In other embodiments, the low-pass decimation filter is implemented for all digital 306 may have its individual parameters as needed to achieve various filtering characteristic width from the digital processing section 103 is loaded.

在PCS-1900模式中,抽选低通滤波器306执行一个小量的滤波,实现两个抽选因子。 In the PCS-1900 mode, Decimating Low Pass Filter 306 performs filtering a small amount, to achieve two decimation factor. 在这种模式中,仅一个载波提供给RF部分101(见图2)中的BPF205的带宽中,该部分101执行对于PCS-1900模式的滤波的主要部分。 In this mode, only one carrier is supplied to the RF section 101 (see FIG. 2) in a bandwidth BPF205, the portion of the main portion 101 performs filtering for the PCS-1900 mode. 对于I和Q的10比特字的每符号4个样值,每秒1.0833兆样值的每个都被变换为10.833Mbs的串行格式,以便数字信号处理。 For each symbol of I and Q 10-bit word of four samples, each 1.0833 megasamples per second values ​​are converted into the serial format 10.833Mbs to digital signal processing. 数字信号处理器利用其串行口帧脉冲标出字边界。 A digital signal processor using its serial port frame pulse mark word boundaries.

在TDMA模式中,抽选低通滤波器306执行滤波的基本量,还实现2.1667MHz主取样速率与被滤波的信道的97.2KHz取样速率的同步。 In the TDMA mode, Decimating Low Pass Filter 306 performs a substantial amount of filtering, but also to achieve synchronization 97.2KHz sampling rate with the sampling rate 2.1667MHz main channel filtered. 滤波器以符号速率的89倍对TDMA载波每秒取样24.3千符号。 Filter to 89 times the symbol rate of the sampled TDMA carrier 24.3 kilo symbols per second. 这种滤波提供了对于邻近的和另外的一些信道的足够的衰减,以满足IS-137A标准的要求。 This filtering provides sufficient attenuation to the adjacent channels and some further to meet standard IS-137A requirements. 被滤波的信号然后由97.2KHz的时钟信号327再取样,并具有由数字处理部分比特定时恢复算法进行控制的相位。 Filtered signal is then re-sampled by the clock signal 327 97.2KHz, digital processing portion and having a bit timing recovery algorithm for phase control. 因为97.2KHz不是2.1667MHz除以一个整数的数,所以该再次取样等效于一个符号的峰峰之间的取样抖动的大约1.1%。 Because 97.2KHz 2.1667MHz not divided by an integer, so that once again the sample is equivalent to one symbol peak to peak sampling jitter between approximately 1.1%. 这种抖动量不会明显影响解调性能。 This jitter amount does not significantly affect the demodulation performance.

对于TDMA模式,该滤波器的输出具有对I和Q样值的10比特的每个的972kbps的串行比特速率,通过多导线线路325连接这些信号到数字处理部分103。 For TDMA mode, the output of the filter having a serial bit rate of the I and Q samples of each of the 10 bits of 972kbps, which is connected to the digital signal processing section 103 through the multi-conductor line 325.

在大多数普通的转移的情况下,终端可以遵守的每个标准的完整的可执行码被包含在内置的非易失存储器中。 In the most general case of transfer, each terminal may observe standard integrity executable code is contained in a built-in non-volatile memory. 当标准被识别时,对于相关标准的可执行码作为操作码被访问和被发送到易失存储器中。 When the standard is identified, the executable code for the relevant standard is accessed and sent to volatile memory as the operation code. 即使在这种情况下,经由一种下载功能通过使用非易失存储器的可写入性,修改、升级和增加也是可能的。 Even in this case, for downloading via the functionality through the use of writable nonvolatile memory, modification, upgrading and adding also possible. 通过制造时提供对于各种规模只读存储器(ROM)或非易失存储器的选择,以成本有效的方式,使得相同的硬件设计可以使手机成为按照一种标准或另外一种标准专用功能的,或者按照由检测所接收信号的特性具有自动适应两种或多种标准的能力。 For all sizes provide a read only memory (ROM) or non-volatile memory by selecting the time of manufacture in a cost effective manner, so that the same hardware design can make the cell phone in accordance with a standard or another standard dedicated functions, or it has the ability to automatically adapt to two or more standard according to the characteristic of the signal received by the detector.

虽然,此刻本发明的大多数的直接应用是蜂窝电话,但是对于本专业的技术人员来说,本发明的固有原理可以被应用到存在多种通信标准的任何场合。 Although, at the moment the most direct application of the present invention is a cellular telephone, but for the person skilled in the art, the principles inherent in the present invention may be applied to any case where there are multiple communication standards.
