Abstract

为了简化用于移动通信的终端中的移动无线电接收机集成后的电路,本发明提出了这样一种接收部分的使用,其中,至少一个组件还用于接收广播信号,执行步骤以确保在广播接收中瞬时出现的间隙被屏蔽,该瞬时是接收用于移动通信的控制信息的瞬时。

Description

具有集成广播接收机的移动无线电接收机
本发明涉及一种用于移动通信的装置，例如具有集成广播接收机的移动无线电接收机。
例如，DE4141382A1中描述了一种装备有诸如计算机、录音装置、遥控以及广播和/或电视接收机之类的多个附加功能的无绳附加特征电话。具有电话功能的元件，例如，数字衰减器，功能键以及特别是电源必须由电话和集成的附加功能一起共享。
因为为了完全可利用性移动通信装置即使在它不使用时也必须接收控制信号，所以在移动通信装置中例如按键、显示屏以及电源之类的移动通信装置的其他部分的共用很不成功。
本发明的一个目的就是使移动通信终端的电路元件能共用于广播信号的接收。
这个目的是这样达到：因为接收部分的至少一个组件被安排来接收广播信号，执行步骤以便在接收移动通信的控制信号时屏蔽发生在广播接收中的间隙。
事实上，优点就是现在移动无线电话接收机的组件还可用于广播接收，而听众不会察觉到控制信息接收之后出现的间隙。应该注意，当数字信号处理器(通常出现的任何方式)用于屏蔽广播信号中的间隙时，用于广播接收机功能所需的附加空间小于广播接收部分和移动无线电话接收机的接收部分相互相邻地集成时的间隙。
在下文将参考表示在附图中的实施例来详细地描述本发明。这里：
图1表示根据本发明的接收机的电路图；
图2表示第一实施例，其中仅仅接收级的给出电路元件共用于移动无线电接收和广播接收，以及
图3表示第二实施例，其中集成的接收级完全用于移动无线电信号和广播信号的接收。
图1表示根据本发明的接收机的基本概念。接收部分1尽可能多的组件共用于移动无线电信道和电台的接收；进一步的处理由音频级2和数字信号处理器3来进行以便通过扩音器4或头戴式送受话器(headset)进行再现。在广播接收期间，控制装置5在规定的瞬间把接收部分切换到移动无线电频带中的控制信道的接收。在此期间，数字信号处理器3产生屏蔽广播频带中的接收间隙的替代信号，该间隙是由控制信息的接收引起的。例如，到此为止，数字信号处理器仅在转换之前重复广播频带中接收的序列，例如，在接收的音频信号的最后20ms。
图2表示用于GSM,DCS1800和VHF频带中的广播信号的多频带无线电装置的接收部分1的可行实施例。该接收部分的大部分组件包含在集成电路IC中。因为发射部分不被广播接收机使用，所以不构成本发明的一部分，且为了清楚的缘故而将其省略。那些对于本领域的技术人员来说是熟知的其它组件，例如键盘、显示元件以及电源，对于移动无线电接收与广播接收它们都以熟知的方式进行使用，并因此也被省略。
第一天线6和第一预滤波器7用于接收DCS1800频带，第二天线8和第二预滤波器9用于接收GSM频带而第三天线10和第三预滤波器11用于VHF广播接收。各个接收信号通过分开的预放大器12,13,14用于分开混合的各级15,16,17。可是，混频在单个振荡器18中产生，其使用PLL电路并且对所有混频级是共用的并因此对于所有频带来说也是共用的。在本实施例中的PLL电路包括石英振荡器19、外部与集成电路IC相连的石英晶体、自动频率控制单元21、锁定检波器22、时序开关元件23、预计数器24、程控计数器25、相位检波器26、电荷泵27、移位寄存器28、站存储器29以及外部连接到IC上的低通滤波器30。
本实施例选择的接收的概念是近零的中频概念，与接收频率相比，其应用低中频，例如，100kHz。每次接收的频带提供给第一自动增益控制器31并随后通过多相近零中频滤波器32。之后，GSM和DCS1800的接收信号在第二自动增益控制器33、缓冲放大器34和模数转换器35中进一步进行处理，但是具有第三自动功率控制器37和多相FM检波器38的并行处理分支用于广播信号。
通常来说，对于根据本发明的概念，必须在一方面用于接收移动无线电频带和广播频带的接收部分的各个电路元件的共用和另一方面能实现这样的电路元件的共用的费用两方面之间寻找一个折衷方案。在前述的实施例中，仅仅在共用的PLL电路中增加费用，例如，因为在广播发射机中的频率不像移动无线电发射机中的那样稳定，因此对于广播发射机的波动的发射频率，接收频率必须再调整。
但是在第二实施例中，一个集成电路(本实施例中的Philips电路OM5178)也完全无修改地用于广播信号频带的接收。仅仅是由于移动无线电频带和广播频带的接收频率不同，所以PLL需要一个更低的参考时钟。按照本发明的此概念，GSM接收信号和广播接收信号通过分开的天线40、42以及分开的预滤波器41、43来接收以便通过第一开关45和第一平衡转换器46提供给集成电路IC的高频信号输出端。而且，对于GSM频带和广播频带来说，提供分离的、外部的、可控制的振荡器47、48，其通过外部PLL滤波器49接收包括在集成电路IC中的PLL开关电路的相应控制信号。通过第二开关50选择相关的可控制振荡器的输出信号以便通过第二平衡转换器51将其提供给集成电路。此外，由于广播频带必需的较低参考频率，所以通过可由数字信号处理器DSP调整的分频器53使用外部振荡器52，可以提供其输出信号。然后广播接收的所有特殊的功能(例如，立体声检波)以及包含在广播信号中的其它功能的检波(例如，RDS(无线电数据信号))完全在数字信号处理器DSP中或者在基带音频接口BAI中执行。例如，对广播到广播发射机的波动的接收频率进行再调整的AFC信号在基带音频接口中产生并被提供给用于调整广播接收频率的可控制振荡器48的第二控制输入端上。
当然，频带GSM和DCS1800仅仅通过例子给出。本发明同样可以很好地用于其他接收频带，只要在备用状态下必须随时接收控制信息。
