图1描述了通信设备100的示意性实施例。通信设备100可以包括无线收发机102(这里具有独立的发射和接收机部分)、用户接口(UI)104、电源114和用于管理其操作的控制器106。无线收发机102可以利用诸如蓝牙、WiFi、数字增强型无绳通信(DECT)之类的短距离或长距离无线接入技术，或蜂窝通信技术等。例如，蜂窝技术可以包括CDMA-1X、WCDMA、UMTS/HSDPA、GSM/GPRS、TDMA/EDGE、EV/DO、WiMAX和正出现的下一代蜂窝无线通信技术。
UI 104可以包括可下压或触敏键区108，具有诸如滚动球、操纵杆、鼠标或用于操纵通信设备100的操作的导航盘之类的导航机制。键区108可以是通信设备100的外壳组件的构成部分，或者可以是通过带缆有线接口(如柔性电缆)或支持例如蓝牙的无线接口与之操作耦合的独立设备。键区108可以表示通常由电话所使用的数字拨号键区，和/或具有数字字母按键的Qwerty键区。UI 104还可以包括显示器110，如单色或彩色LCD(液晶显示器)、OLED(有机发光二极管)或其它适合的显示器技术，用于向通信设备100的终端用户传递图像。在显示器110是触感显示器的实施例中，可以通过显示器来呈现键区108的一部分或全部。
电源114可以利用普通功率管理技术(如可替换电池、电源调节技术和充电系统技术)，用于向通信设备100的组件提供能量，以促进便携式应用。控制器106可以利用计算技术，如具有诸如闪存、ROM、RAM、SRAM、DRAM之类的相关存储器的微处理器和/或数字信号处理器(DSP)，或其它类似技术。
图2描述了图1的通信设备100的无线收发机102的一部分的示意性实施例。在GSM应用中，收发机102的发射和接收部分可以包括经由开关204与可调谐匹配网络202相耦合的通用放大器201、203和阻抗负载206。本说明中的负载206可以是如图1所示的天线(这里是天线206)。射频(RF)信号形式的发射信号(TX)可以送往放大器201，放大器201对信号进行放大，并在针对发射会话启用开关204时将放大后的信号通过可调谐匹配网络202送往天线206。收发机102的接收部分可以利用前置放大器203，前置放大器203在针对接收会话启用开关204时放大经由可调谐匹配网络202从天线206接收的信号。图2的其它配置可用于其它类型的蜂窝接入技术，如CDMA。可以通过本公开预想这些未公开的配置。
图3-4描述了图2的收发机102的可调谐匹配网络202的示意性实施例。在一个实施例中，可调谐匹配网络202可以包括控制电路302和可调谐电抗元件310。控制电路302可以包括DC-DC转换器304、一个或多个数模转换器(DAC)306和一个或多个相应的缓冲器308，以放大由每个DAC产生的电压。所放大的信号可以馈送至如图5中示出的一个或多个可调谐电抗组件504、506和508，图5描述了可调谐电抗元件310的可能电路配置。在该说明中，可调谐电抗元件310包括三个可调谐电容器504-508和具有固定电感的电感器502。也可以由本公开预想其它电路配置。
可调谐电容器504-508可以各利用启用所述组件的电容的可调谐性的技术。可调谐电容器504-508的一个实施例可以利用电压或电流可调谐介电材料，如钛酸钡锶(BST)化合物。BST化合物的示例是
Figure BDA0000151789790000041
可调谐电容器。在另一实施例中，可调谐电抗元件310可以利用半导体变容二极管。本公开可以预想可以支持电压或电流可调谐电抗元件的方式的当前或下一代方法或材料化合物。
DC-DC转换器304可以从图1中的通信设备100的电源114中接收如3V的功率信号。如图所示，DC-DC转换器304可以使用普通技术，将该功率信号放大为更大范围(例如，30V)。控制器106可以通过“n”或更多线的控制总线，向每个DAC 306提供数字信号，以单独控制可调谐电容器504-508的电容，从而改变可调谐匹配网络202的集合电抗(collective reactance)。可以以双线普通串行通信技术(如，串行外设接口(SPI)总线)来实现控制总线。利用SPI总线，控制器106可以提供串行化数字信号来配置图3中的每个DAC，或图4的可调谐电抗元件404的开关。图3的控制电路302可以利用普通数字逻辑来实现SPI总线，并将控制器106提供的数字信号送往DAC。
在另一实施例中，可调谐匹配网络202可以包括解码器形式的控制电路402、以及包括如图6所示的可开关电抗元件的可调谐电抗元件404。在该实施例中，控制器106可以经由SPI总线给控制电路402提供信号，可以利用普通布尔或状态机逻辑对该信号进行解码，以单独启用或禁用开关元件602。可以利用半导体开关或如在微型机电系统(MEMS)中使用的微电机开关来实现开关元件602。通过利用开关元件602来独立地启用和禁用图6的电抗元件(电容器或电感器)，可以改变可调谐电抗元件404的集合电抗。
可调谐匹配网络202、204的可调谐性向控制器106提供了优化收发机102的性能参数的方式，例如但不限于，发射机功率、发射机效率、接收机灵敏度、通信设备的功耗、人体对能量的特定吸收率(SAR)、频带性能参数等。为了实现设计者可以定义的一个或多个期望性能特性，通信设备100可以置于如图7所示的隔音室706中。在该配置中，设计者可以执行通信设备100的性能参数(如总辐射功率(TRP)、总各向同性灵敏度(TIS)或辐射谐波测量、接收机效率、发射功率效率和功耗等)的校准测量。针对多频带通信设备100，可以每个频带或每个子带执行校准测量。
此外，可以在利用模拟人体组成的人体模型的通信设备100的多个使用情况下执行校准测量。例如，具有翻盖设计的外壳组件的通信设备100在打开翻盖时会被置于紧邻人体模型的耳朵，以模拟典型的会话使用情况。在例如用户利用蓝牙耳机或通信设备100处于待机模式时的无需手的应用中，通信设备100可以关上翻盖被置于人体模型的臀部。可以针对例如通信设备100被握在人体模型的手中但远离人体模型的头部的情况下天线拉起(antenna up)或放下(down)、免提特征“开”之类的其它使用情况来执行校准。任何数量的使用情况可以如所期望地应用于每个频带和子带。
如图7中所描述，计算机702可以经由具有同轴连接的蓝牙至USB适配器，与位于隔音室中的通信设备100通信耦合。计算机702还可以与也通过同轴缆线连接与隔音室相连的通信系统分析器704(可以放置并接收活跃的“电话呼叫”给蜂窝手机)通信耦合。计算机702可以控制通信系统分析器704和图2的可调谐匹配网络202。通信设备100的控制可以执行蓝牙串行端口简档(SPP)，该SPP向计算机702提供了通过图3或4的控制电路302或402发送测试命令、控制DAC设置、或切换设置的方式。尽管未示出，图7的校准环境可以包括附加测试设备，该设备可以测量通信设备100的功耗、SAR、谐波或其它有用的性能参数。因而，通过本公开可以预想通信设备100的任何可测量性能参数。
图8描述了在图7的测试环境的部分中操作的示例性方法800。方法800可以以下述步骤开始：计算机702指引通信设备100的操作和可调谐匹配网络202的配置，以执行通信设备100的一个或多个性能参数(例如，TX功率、经由接收信号强度指示或RSSI的RX灵敏度、功耗等)的实际测量。例如，假设可调谐匹配网络202包括三个DAC，每个DAC具有从0到3V的32个可配置输出电压，如图3所示。三个DAC将会提供可以供给图5的三个可调谐电容器504-508的电压的32，768(32*32*32)个组合。还假设收发机102支持世界漫游的4个频带，通信设备100的设计者将会测试每个频带的3个使用情况。在这些条件下，设计者将必须执行针对感兴趣的每个性能参数的393，216个校准测量，这会导致上百万次测量。
然而，步骤802可以适于执行DAC 306的可能调谐状态的子集。例如，计算机702可以适于针对每个DAC的五个调谐状态执行校准测量。在这些约束下，校准测量可以限制为感兴趣的每个性能参数的125(5*5*5)个校准测量。如果包括4个频带和3个使用情况，则总校准测量可以合计1500个测量，这明显实质上小于校准测量的全扫(fullsweep)。
仅出于示例目的，将假设如图3所示的调谐匹配网络202仅具有2个DAC，每个DAC支持20个可调谐电平。还假设5个调谐状态的子集用于步骤802。在这样的前提下，图9描述了基于RSSI测量来接收灵敏度数据的25个校准测量的数据集。图9的图形示出了1dB等值线带(contour band)。从图9中明显看出，等值线带902-914并不平滑。由于两个原因而出现参差不齐的带。第一，因为通信设备100可以仅提供非分数RSSI数据，所以RSSI数据点是不精确的。其次，缺少的调谐状态产生台阶效应，这产生了等值线带之间附加的参差不齐的边缘。
在步骤804中，计算机702可以适于应用普通数学拟合函数g(v1，v2，...)，以对未包括在步骤802的子集中的那部分调谐状态的系统性能进行建模。拟合函数还可以降低RSSI数据中的不精确度。拟合函数可以是利用普通回归算法来在从步骤802中得到的实际测量之间进行内插的三或四阶函数。出于示例目的，以下是三阶拟合函数的例子：
c1+c2x+c3y+c4x2+c5y2+c6xy+c7xy2+c8x2y+c9x3+c10y3
常数c1-c10适于经过迭代过程来执行三阶拟合函数。可以通过本公开预想其它拟合函数。图10描述了向图9的RSSI数据集应用拟合函数的结果。从图10中很明显地看出，1dB等值线带1002-1012已经基本上被平滑，以更精确地反映实际的RSSI测量，并估计针对未包括在步骤802的子集中的DAC 1和2的调谐状态而测量的RSSI测量。
图11描述了用于利用步骤802中使用的调谐状态的子集执行的发送功率测量的数据集的示例。针对该示例的1dB等值线带1102-1120没有图9的等值线带902-914那样参差不齐，因为TX功率测量从可以将分数结果(fractional result)提供给计算机702的网络分析器中得到。图12描述了从步骤804中应用上述拟合函数而产生的数据集。正如在该示例中显而易见地，当与图11的等值线带1102-1120相比较时，拟合函数产生更平滑的等值线带1202-1220。
一旦在DAC 1和2的整个调谐状态上，在步骤804中拟合了每个性能参数(例如RX灵敏度、TX功率等)的数据集，则计算机702可以利用计算机软件进行到步骤806，在步骤806中可以向通信设备100的设计者呈现定义期望品质因数(FOM)的选项，这可以用于确定提供了针对期望FOM的最优解决方案的调谐状态。例如，FOM可以表示期望功率发送效率(电池功率耗用上的TX功率)。FOM也可以表示在其中会不期望最优性能的“疏排”区域。FOM也可以在数学上组合性能参数(例如，TX功率+RX功率)。
一旦设计者定义了FOM形式的通信设备100的一个或多个期望性能特性，则计算机702适于在步骤808中通过以精细增量扫过普通数学模型来获得期望FOM的调谐状态范围，以找到关于期望FOM的全局最优性能。计算机702适于在步骤810中向用户呈现在每个频带上，每个使用情况的基础上获得期望FOM的调谐状态范围。用户可以在步骤812中选择一部分调谐状态，以在可由通信设备100在操作期间利用的查找表中存储。图13描述了根据频带和使用情况，可由图1的通信设备100的控制器106在操作期间编索引的查找表的图示。
在消费者的正常操作期间，通信设备100可以检测设备的多种可能使用情况。例如，通信设备100可以基于在通信设备100中操作的呼叫处理软件的状态，检测消费者调用了呼叫或应答了呼叫。在通信设备100中操作的呼叫处理软件也可以检测哪些频带或子带正用于活跃的呼叫。通信设备100还可以利用普通电动机械传感器来检测翻盖外壳组件已经打开。
通信设备100还可以从呼叫处理软件中检测在发生通信会话时禁用蓝牙耳机特征和免提特征。通信设备100还可以利用普通电动机械传感器来检测天线是拉起还是处于关闭位置。通信设备100还可以利用接近性传感器和/或定位传感器(例如，加速计)来检测该设备是否位于用户的身体附近，以及该设备是位于水平或是垂直位置。
存在可通过本公开预想的许多可检测使用情况。这些可检测状态可以全部或部分地向通信设备100提供预测任意数量的使用情况的似然的方式。一旦检测用户情况，则通信设备100可以根据频带(或子带)和使用情况来对表13的查找表编索引，以识别使通信设备100以所述通信设备100的设计者所预想的期望方式进行操作的图2的可调谐匹配网络202的期望调谐状态。
图14描述了支持WiFi、PSTN和蜂窝通信、以及通信设备100可以根据其进行操作的因特网服务的混合通信系统1400的示意性实施例。通信系统1400是示意性而非限制性的。也就是说，本公开可以预想其它有线或无线通信技术，如通过电力线的以太网、蓝牙、WiMAX、软件定义无线电等。图15描述了可以另外由通信设备100使用或由通信设备100与由方法800所描述的上述实施例相结合使用的方法1500。
方法1500以步骤1502开始，其中通信设备100建立与通信系统1400的通信会话。通信会话可以是采用普通无线接入技术(如GSM、CDMA、UMTS、WiFi、蓝牙或其组合)的无线通信会话。在一个实施例中，在步骤1504，通信设备100可以根据所提供的标识符来识别通信系统100。通信标识符可以是由3GPP标准定义的公共陆地移动网络(PLMN)标识符、服务集标识符(SSID)、小区标识符(3GPP标准中的CELL Id)、或可以识别通信系统1400的通信元件(如蜂窝基站或诸如WiFi接入点之类的其它普通无线接入点)的另一形式的标识。
在步骤1506，通信设备100可以根据标识符来选择简档。简档可以表示指令集、查找表或其组合，以供给可调谐匹配网络202。尤其，简档可以包括一天中的时间的供给信息、与通信设备的操作位置相关联的供给信息、用于调谐通信设备的接收机部分的供给信息、或用于调谐通信设备的发射机部分的供给信息。
供给信息的上述实施例中的任何一个或多个组合可以指导通信设备100供给可调谐匹配网络202，以根据一天中的时间的考虑(如，高和低网络业务条件)、通信设备100的操作位置(如城市漫游、郊区漫游等)、针对接收机部分和/或发射机部分的特定调谐指令来适配图1的收发机102的发射机部分和/或接收机部分的性能参数。这些实施例是非限制性的。因而，本公开可以预想其它适合的供给指令。
简档中包括的供给信息可以由网络运营商根据通信系统1400的上行链路和/或下行链路通信特性来确定。通信设备100的性能参数可以包括但不限于通信设备100的功耗、通信设备的发射机部分的辐射功率、发射机部分的线性、通信设备的接收机部分的接收灵敏度、或接收机部分的信道选择性。
供给信息可以用于控制收发机102的操作效率、电池寿命或其它普通期望性能度量。供给信息也可以用于以通信设备100的发射机部分的操作特性为代价来提高通信设备100的接收机部分的操作特性，反之亦然。
在另一实施例中，可调谐匹配网络202可以用作可调谐滤波器网络，以控制接收机或发射机部分的操作。简档中提供的供给信息可以用于例如改变用于使接收机部分失谐的滤波器，如将在以下所讨论，这会具有有用的结果。
步骤1508-1512呈现了利用简档的附加实施例。例如，在一个实施例中，通信设备100可以从通信系统1400的通信元件接收请求，以利用可以在步骤1510中选择的特定简档。在一个实施例中，通信设备100可以在步骤1512中从通信元件接收简档(对现有简档的补充或修改)。响应于步骤1504-1512的实施例，在步骤1514中，通信设备100可以供给可调谐匹配网络202。
在另一实施例中，可以对通信设备100进行编程，以在没有来自通信系统1400的指令的情况下和/或独立于通信设备操作的通信系统1400，来确定自动调谐的需求。通信设备100可以在步骤1516中做出该确定。可以根据简档来确定自动调谐条件，该简档能够识别接收机或发射机操作特性，该接收机或发射机操作特性保证经由可调谐匹配网络202的调谐状态的适配对通信设备100的性能参数进行调整。例如，如果接收机和发射机的链路余量高，则通信设备100可以独立地选择自动供给可调谐匹配网络202，以提高通信设备的功耗。
根据上述简档的各方面进行管理的通信设备100的适配性能参数可以由通信系统1400的通信元件用于在步骤1520中适配所服务的全体通信设备的通信服务。例如，作为多个通信设备100优化发射机线性以降低频带干扰的结果，通信元件可以提供增大的系统容量，从而提高整个系统容量。
通常而言，不同的网络运营商可以部署彼此不同的基础设施(基站和天线塔和天线系统)，相应的一些网络可以是“上行链路受限”的，一些可以是“下行链路受限”的。这意味着，在一些网络中，手机发射机和基站接收机之间的链路可以具有比基站发射机和手机接收机之间的链路少的总损失，反之亦然。在这种情况下，可以改变手机中的可调谐匹配网络202以适应这种差异。
例如，在网络是下行链路受限的情况下，对通信设备100的手机天线调谐器来说，强调以发射频带中的匹配为代价来提高手机接收频带中的天线匹配是恰当的。这可以是针对该特定网络提高整体性能或链路余量的方式。相反，如果网络是上行链路受限的，则以接收频带为代价来提高手机发射频带中的匹配是恰当的。
如果该信息已知，则上述调谐器查找表可以扩展为包括网络标识(例如，PLMN)的输入，针对不同的通信网络有适合的不同的调谐器设置。此外，甚至在网络(PLMN)内，如果网络运营商知道其网络内特定位置中的特定问题，则查找表可以是专门用于单个小区站点标识的。
当确定可调谐匹配网络202的设置时还有另一方面要考虑，即在1518基于手机本身的实际发射机和接收机条件来自主地确定最优设置。例如，蜂窝手机发射机通常采用可以在来自正与它们进行通信的基站的方向上被调整到输出功率电平范围的功率放大器。手机控制器可以知道任意时刻的发射功率设置，并且还可以知道在任意时刻从基站接收到的接收信号强度。
利用这些发射和接收电平的知识，控制器可以确定是否应当改变天线匹配以提高在发射或接收频带中的匹配。在上行链路和下行链路路径均具有余量(发射机处于较低功率电平且接收机看到高信号功率)的情况下，可以将可调谐匹配调整到优化发射机效率(以减小电流耗用，从而提高电池寿命)的位置或优化发射机线性(以降低频带干扰，以提高整个系统容量)的位置。
可调谐匹配网络202的另一可能使用是有意地使接收频带中匹配的性能失谐或降级，同时保持在手机的发射频带中的良好匹配(针对发射功率、效率或线性)。这样做的原因将会是使接收机较不灵敏，且相应地不太易受本地干扰信号的影响。如前所述，通过检测强期望接收信号，手机控制器可以自主地将调谐器设置到如下状态：使手机内接收机路径中的损失增加，同时保持与发射机的良好匹配。
另一个实施例是考虑将可调谐匹配网络202作为可调谐滤波器网络。相应地，有意地在接收带中使网络失谐等同于对滤波器的通带进行调谐，以只包括发射频带，但是部分拒绝接收频带。
网络运营商也可能偏好在手机处于具有良好的链路余量(上行链路和下行链路)的情况下时，手机优选地将天线匹配调谐到将会基于一天中的实际时间改进当前耗用或线性的位置。在工作日的特定时间(例如在上班高峰期间)，网络运营商可以优选优化手机线性来优化繁忙电话呼叫业务的那些时段的网络容量。
可以在制造手机时将这种网络优选调谐加载到查找表中，但是能够重新编程、或通过空中供给该信息对运营商来说是有用的。这可以给运营商带来灵活性，以在对系统每次作出改变时，增强在通信系统1400中操作的通信设备100的操作，或者在系统中发现影响整体性能的条件，可以通过在遇到这些条件时修改手机如何工作来改进整体性能。在无线网络中有几种方法可以实现这种供给。例如，可以在短消息服务(SMS)、WAPPUSH、多媒体消息收发服务(MMS)消息、通过因特网协议的直接数据信道连接、SIM Took Kit消息、开发移动联盟(OMA)规定的空中标准、或通过诸如在基于iPhone或Android的电话中使用的专利方法中提供简档。
调谐应用的另一个实施方式可以是将其并入3GPP SIM Toolkit规范。该调谐应用可以从通信系统中的相应的调谐应用中接收查找表信息。该查找表可以包含与手机应如何执行相关的任意数量的参数，例如线性、失谐、发射加权、接收加权、电池寿命加权等。网络调谐应用也可以提供与应该何时或何地选择特定性能简档相关的其它特定信息，例如：
●网络Id(3GPP标准中的PLMN)
●小区标识符(3GPP标准中的CELL Id)
●一天中的时间
●一周中的天
●制造商ID(部分手机序列号，例如3GPP IMEI)
利用合适的查找表，手机可以将所有这些参数应用于特定性能简档。网络调谐应用可以针对手机制造商选择特定简档，以及以在特定通信小区区域中实现更加均一的性能为目的，利用特定性能简档对手机进行建模并将其作为目标。
从上述描述中，本领域技术人员显而易见，在不偏离以下描述的权利要求的范围和精神内可以修改、减少或增强上述实施例。例如，图8和15的方法800和1500可适于用于校准和供给有线收发机的可调谐匹配网络。方法800和1500可以应用于使用情况、频带、频带子集合、以及在本公开中未提及的其它性能参数的各种组合。可以通过本公开预想这些未公开的组合。
