具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
本发明实施例提供一种功率定标方法，该方法适用于至少一种网络制式，即该方法可以用于单模多载波***中，也可以用于多模多载波***中，其中，网络制式可以包括以下一项或多项：全球移动通信***(GSM，Global System for Mobile Communication)，通用移动通信***(UMTS，Universal Mobile Telecommunications System)，长期演进(LTE，Long Term Evolution)，时分同步码分多址(TD-SCDMA，Time Division-Synchronous Code Division Multiple Access)，码分多址(CDMA，Code Division Multiple Access)；其中，LTE中可以包括时分双工(TDD，Time Division Duplex)、频分双工(FDD，Frequency Division Duplex)。
图1为本发明实施例中功率定标方法的流程示意图，如图1所示，该方法包括：
S101：配置各网络制式下各载波，对各载波进行混频合路得到合路信号；
图2为本发明实施例中功率定标方法的一种可选的流程示意图，下面以图2为例进行说明；
如图2所示，第一步，功率定标装置接收定标使能信号，在定标的使能信号有效时进行定标启动，具体来说，功率定标装置主要检测该单模或多模***中的放大器(PA)的各项指标是否满足要求、射频拉远单元(RRU，Radio Remote Unit)中的各模块是否准备就绪、PA驻波等。第二步，功率定标装置进行定标初始化，具体来说，由于功率定标装置中各射频参数设置不确定，需要进行初始化操作，并产生定标的初始化信息，这里，在定标初始化的过程中，设置各网络制式下各载波的功率增益的初始值为0，以防止各载波在处理的过程中，PA在强行打开后出现大功率。
功率定标装置在进行定标初始化之后，得到定标的初始化信息，功率定标装置是根据定标的初始化信息来配置出各网络制式下各载波中，这里需要说明的是，功率定标装置可以根据定标的初始化信息配置出一种网络制式下的多载波，也可以根据定标的初始化信息配置出多个网络制式下的多载波。
图3为本发明实施例中功率定标方法的一种可选的流程框图；下面结合图2和图3来进行说明；
如图3所示，功率定标装置配置出N个载波，第一个载波用I(1)，Q(1)表示，第N个载波用I(N)，Q(N)来表示，功率定标装置并行传输上述N个载波，对上述N个载波进行数字下变频处理(DUC，Digital Down Converter)和混频合路处理，这里，功率定标装置可以针对每种网络制式下的载波进行混频合路处理得到每种网络制式下的合路信号，也可以将所有载波进行混频合路处理得到一个合路信号，这里，本发明实施例不做具体限定。
S102：对合路信号进行处理得到处理后的合路信号，对处理后的合路信号进行分载波，得到处理后的各载波；
仍然以图3为例，功率定标装置在得到合路信号之后，对合路信号依次进行数模转换(D/A)处理、PA处理和模数转换(A/D)处理，得到处理后的合路信号进行分载波。在图3中，第一个处理后的载波用I(1)'，Q(1)'表示，第N个处理后的载波用I(N)'，Q(N)'来表示。
这里，需要说明的是，本发明实施例中各载波的功率增益指的是，配置出的各载波经过混频合路处理得到处理后的合路信号的链路上的功率增 益，该链路也可以称之为发射链路。
S103：检测处理后的各载波的功率；
举例来说，图3中，功率定标装置在得到第一个处理后的载波至第N个处理后的载波之后，检测处理后的各载波的功率(相当于图3中为数字分载波功率检测)，并将检测到的各载波的功率上报给功率定标装置中的中央处理器(CPU，Central Processing Unit)后台。
S104：在处理后的各载波的功率未落入预设数值范围时，根据处理后的各载波的功率，调整各载波的功率增益，返回至检测处理后的各载波的功率的步骤，在处理后的各载波的功率落入预设数值范围时，各载波的功率定标结束。
其中，上述预设数值范围是功率定标装置根据定标的要求预先配置好的，只有当各载波的功率落入该预设数值范围时，说明发射链路上的发射功率达到了定标的要求，那么，各载波的定标结束，否则，需要重新返回至检测处理后的各载波的功率的步骤，再次根据处理后的各载波的功率来调整各载波的功率增益，直到处理后的各载波的功率落入预设数值范围，这样使得发射链路上的发射功率的发射功率达到了定标的要求，该方法可配性好，兼容性高，能够兼容各种网络制式下的多模或混模的功率定标需求，用户可以根据不同的应用场景根据定标需求进行灵活的配置。
为了更加达到功率定标的要求，需要调整各载波的功率增益，首先，功率定标装置对各载波的功率增益进行粗调，在一种可选的实施例中，在S104中根据处理后的各载波的功率，调整各载波的功率增益，可以包括：将处理后的每个载波的功率与每个载波的预设值之间的差值确定为每个载波的功率差值；根据每个载波的功率差值，确定对应的第一调整值，根据确定的第一调整值调整各载波的功率增益。
具体来说，在图3中，当功率定标装置中的CPU后台接收到上报的处理后的各载波的功率之后，首先，计算处理后的每个载波的功率与每个载波的预设值的差值，得到每个载波的功率差值，然后确定出每个载波的功率差值对应的第一差值，例如，在每个载波的功率差值均大于0.1mW时，确定的第一差值可以为0.1dB，然后将各载波的功率增益增大或者减小 0.1dB；然后再检测处理后的各载波的功率，根据检测到的各载波的功率来调整各载波的功率增益，这样，对各载波的功率增益进行粗调，直至经过调整后的各载波的功率增益满足预设条件。
功率定标装置根据处理后的各载波的功率对各载波的功率增益进行粗调，为了提高功率定标的精度，需要对各载波的功率增益进行微调以提高功率定标的精度，在一种可选的实施例中，在S101之后，该方法还可以包括：检测合路信号的功率；
在S102中在对合路信号进行处理得到处理后的合路信号之后，在对处理后的合路信号进行分载波，得到处理后的各载波之前，该方法还包括：检测处理后的合路信号的功率；
在调整后的各载波的功率增益满足预设条件时，根据合路信号的功率和处理后的合路信号的功率，调整各载波的功率增益。
上述根据合路信号的功率和处理后的合路信号的功率，调整各载波的功率增益是在调整后的各载波的功率增益满足预设条件时，也就是说，微调是在粗调满足预设条件的基础上进行的，上述预设条件可以为一个粗调数值区间，只有当粗调后的每个载波的功率差值落入该粗调数值区间时，说明粗调满足预设条件，能够进行微调，进行一次微调之后，只有当检测到的合路信号的功率差值和处理后的合路信号的功率差值满足一定的微调数值区间，才结束微调。
在具体实施过程中，为了通过微调来进一步提高功率定标的精度，在一种可选的实施例中，根据合路信号的功率和处理后的合路信号的功率，调整各载波的功率增益，可以包括：将合路信号的功率与合路信号的预设值之间的差值确定为合路信号的功率差值；将处理后的合路信号的功率与处理后的合路信号的预设值之间的差值确定为处理后的合路信号的功率差值；根据合路信号的功率差值和处理后的合路信号的功率差值，确定对应的第二调整值，根据确定的第二调整值调整各载波的功率增益。
其中，上述第二调整值小于上述第一调整值。
同样，再以图2和图3为例进行说明，功率定标装置在定标初始化完成之后，对配置出的各载波进行混频合路得到合路信号，然后对合路信号 进行处理得到处理后的合路信号，再对处理后的合路信号进行分载波得到处理后的各载波，然后检测各载波的功率，计算每个载波的功率与每个载波的预设值的差值，当每个载波的功率差值均大于0.1mW时，将各载波的功率增益增大或者减小0.1dB，继续对各载波的功率增益进行粗调，直至检测到的每个载波的功率差值均小于或等于0.1mW，然后根据检测到的合路信号(相当于图3中的数字合路功率检测)和处理后的合路信号(相当于图3中的模拟合路功率检测)，对各载波的功率增益进行微调，如图2所示，计算合路信号与合路信号预设值的差值，且计算处理后的合路信号与处理后的合路信号预设值的差值，只有当合路信号的功率差值与处理后的合路信号的功率差值均大于0.01mW，将各载波的功率增益增大或者减小0.01dB，继续对各载波的功率增益进行微调，直至检测到的合路信号的功率差值和处理后的合路信号的功率差值均小于等于0.01mW，结束定标。
这里，采用了粗调和微调，通过粗调先对载波信号进行校正，然后通过微调对合路信号再进行细微的校正，因此对于功率定标的实际检测与调整，灵活性更高，精度也更高；采用了分载波(反馈载波接收信号的强度指示(RSSI，Received Signal Strength Indicator))-合波(反馈合波RSSI)与数字合波(发射信号的强度指示(TSSI，Transmitter Signal Strength Indicator))-模拟合波(反馈RSSI)2组检测调整，能够实现多种2组检测调整，通过2种调整校正的方法，实现了载波功率值与链路输出功率值都校准的目的。
在调整各载波的功率增益中分别进行粗调和微调，粗调中需要检测处理后的各载波的功率，微调中除了检测合路信号的功率，还需要检测处理后的合路信号的功率，那么，为了适时准确地触发检测出处理后的各载波的功率和处理后的合路信号的功率，需要确定出触发检测处理后的各载波的功率和处理后的合路信号的功率的同步信号，在一种可选的实施例中，在S103之后，该方法可以包括：根据功率定标的使能信号，对检测处理后的各载波的功率的检测信号进行同步处理，得到同步信号；根据同步信号，触发检测处理后的各载波的功率；根据同步信号，触发检测处理后的合路信号的功率。
为了得到准确的同步信号来触发检测处理后的各载波的功率和处理后的合路信号的功率，在一种可选的实施例中，根据功率定标的使能信号，对检测处理后的各载波的功率的检测信号进行同步处理，得到同步信号，可以包括：在功率定标的使能信号有效时，对检测处理后的各载波的功率的检测信号依次进行跨时钟域处理、分频处理和延时处理，得到同步信号。
图4为本发明实施例中同步信号的一种可选的流程框图，如图4所示，功率定标装置接收功率定标的使能信号，其中，该使能信号用于功率定标装置在接收到的该使能信号之后，在使能信号有效时定标启动，功率定标装置进行定标检测、定标初始化等等，检测合路信号的功率的检测信号用Fr表示，功率定标装置对检测信号Fr先进行跨时钟处理，以统一发射链路上的时钟域与反馈链路上的时钟域，避免功率定标装置中的硬件电路产生异常，为了保证兼容性，其中，反馈链路指的是发射链路的数据经过PA，再经过反馈A/D转换后的通道数据处理链路，经过链路的各级处理，可以完成反馈链路的合路以及分载波的功率检测；
分频处理主要是针对各种网络制式的分频处理，保证送入下一级做功率检测的同步信号能适应不同制式的处理，分频处理完成后延时处理，延时处理需要根据不同网络制式和混模条件做不同的延时调整，该调整值来自于下行数据到反馈的延时，由于在检测合路信号的功率之后，对合路信号进行D/A处理、PA处理、A/D处理以及分载波处理，所以，此时需要进行延时处理以检测到准确的处理后的各载波的功率和处理后的合路信号的功率；这样，便得到了同步信号Fr'来触发检测处理后的各载波的功率和处理后的合路信号的功率。
图5为本发明实施例中同步信号的一种可选的时序图，如图5所示，CPU后台配置出功率定标的使能信号，当该使能信号为高电平时，且在检测信号Fr的随路同步帧头处触发检测合路信号的功率得到合路信号的功率用TSSI表示，如图5中的TSSI计算，更新上报TSSI至寄存器，然后对检测信号Fr进行跨时钟处理、分频处理和延时处理得到同步信号Fr'。
这里需要说明的是，在图2中，检测信号不仅用于生成同步信号Fr'，还用于触发对各载波进行混频合路处理得到合路信号，使得功率定标装置 可以不断的检测与调整各载波的功率增益。
另外为了保证在连续的多次功率检测时，下行和反馈的功率检测在同一帧内，在图5中，功率定标装置根据功率定标的使能信号和检测信号Fr不仅生成了同步信号Fr'，同时还生成了前向传给反馈的启动信号，在该前向传给反馈的启动信号为高电平时，经过延时处理t之后检测处理后的各载波的功率和处理后的合路信号的功率，将检测得到的处理后的各载波的功率和处理后的合路信号的功率用RSSI表示，图5中用反馈RSSI表示，在得到RSSI之后，触发前向更新上报TSSI完成标志至寄存器；约几个周期(cycle)之后更新上报RSSI完成标志至寄存器，在检测信号Fr的下一个随路同步帧头处计算反馈RSSI的完成标志上报给CPU，CPU检测到该标志后读取TSSI和RSSI，并在延时处理t之后清除寄存器中的TSSI和RSSI。
经过上述粗调和微调，可以提高功率定标的标精度，并且在产生同步信号中，一般的方案中没有考虑链路和***延时等信息，因此在不做同步处理的时候，数字分载波功率检测，数字合路功率检测以及模拟合路功率检测3个单元的检测值存在较大偏差，上报后台后，软件经过定标计算后配置的新的校准参数与实际链路需要的调整值之间偏差大；而该方案中通过加入同步信号，使得这3个检测值之间误差很小，特别是在数字与模拟合波功率检测单元中，加入握手机制，使得两者的检测误差更小，对整个定标精度有关键意义。
本发明实施例所提供的功率定标方法，该方法适用于至少一种网络制式，功率定标装置配置各网络制式下各载波，并对各载波进行混频合路处理得到合路信号，然后对合路信号进行处理得到处理后的合路信号，对处理后的合路信号进行分载波得到处理后的各载波，再对处理后的各载波进行检测得到处理后的各载波的功率，在处理后的各载波的功率未落入预设数值范围时，根据处理后的各载波的功率，调整各载波的功率增益，返回至检测处理后的各载波，得到处理后的各载波的功率的步骤，在处理后的各载波的功率落入预设数值范围，则各载波的功率定标结束，这样，通过处理后的各载波的功率来调整各载波的功率增益，通过调整功率增益来调整功率，形成了一种闭环反馈的功率调整路径，从而提高了单模及多模系 统中功率定标的定标效率和精度。
基于同一发明构思，本发明实施例还提供一种功率定标装置，图6为本发明实施例中功率定标装置的结构示意图，如图6所示，该装置适用于至少一种网络制式，该装置包括：合路模块61、处理模块62、第一检测模块63和第一调整模块64；
其中，合路模块61，配置为配置各网络制式下各载波，对各载波进行混频合路得到合路信号；处理模块62，配置为对合路信号进行处理得到处理后的合路信号，对处理后的合路信号进行分载波，得到处理后的各载波；第一检测模块63，配置为检测处理后的各载波的功率；第一调整模块64，配置为在处理后的各载波的功率未落入预设数值范围时，根据处理后的各载波的功率，调整各载波的功率增益，并触发所述第一检测模块63检测处理后的各载波的功率，在处理后的各载波的功率落入预设数值范围时，各载波的功率定标结束。
为了更加达到定标的要求，需要调整各载波的功率增益，首先，功率定标装置对各载波的功率增益进行粗调，在一种可选的实施例中，上述第一调整模块64具体配置为将处理后的每个载波的功率与每个载波的预设值之间的差值确定为每个载波的功率差值；根据每个载波的功率差值，确定对应的第一调整值，根据确定的第一调整值调整各载波的功率增益。
功率定标装置根据处理后的各载波的功率对各载波的功率增益进行粗调，为了得到提高功率定标的精度，需要对各载波的功率增益进行微调以提高功率定标的精度，在一种可选的实施例中，上述装置还包括：第二检测模块，配置为在配置各网络制式下各载波，对各载波进行混频合路得到合路信号之后，检测合路信号的功率；第三检测模块，配置为在对合路信号进行处理得到处理后的合路信号之后，在对处理后的合路信号进行分载波，得到处理后的各载波之前，检测处理后的合路信号的功率；第二调整模块，配置为在调整后的各载波的功率增益满足预设条件时，根据合路信号的功率和处理后的合路信号的功率，调整各载波的功率增益。
在具体实施过程中，为了通过微调来进一步提高功率定标的精度，在一种可选的实施例中，上述第二调整模块具体配置为将合路信号的功率与 合路信号的预设值之间的差值确定为合路信号的功率差值；将处理后的合路信号的功率与处理后的合路信号的预设值之间的差值确定为处理后的合路信号的功率差值；根据合路信号的功率差值和处理后的合路信号的功率差值，确定对应的第二调整值，根据确定的第二调整值再次调整各载波的功率增益。
在调整各载波的功率增益中分别进行粗调和微调，粗调中需要检测处理后的各载波的功率，微调中除了检测合路信号的功率，还需要检测处理后的合路信号的功率，那么，为了适时准确地触发检测出处理后的各载波的功率和处理后的合路信号的功率，需要确定出触发检测处理后的各载波的功率和处理后的合路信号的功率的同步信号，在一种可选的实施例中，上述装置还包括：同步模块，配置为在检测处理后的各载波的功率之后，根据功率定标的使能信号，对检测处理后的各载波的功率的检测信号进行同步处理，得到同步信号；触发模块，配置为根据同步信号，触发检测处理后的各载波的功率；根据同步信号，触发检测处理后的合路信号的功率。
为了得到准确的同步信号来触发检测处理后的各载波的功率和处理后的合路信号的功率，在一种可选的实施例中，上述同步模块具体配置为在功率定标的使能信号有效时，对检测处理后的各载波的功率的检测信号依次进行跨时钟域处理、分频处理和延时处理，得到同步信号。
在实际应用中，合路模块61、处理模块62、第一检测模块63、第一调整模块64、第二检测模块、第三检测模块、第二调整模块、同步模块和触发模块均可由位于装置的CPU、微处理器(MPU，Microprocessor Unit)、专用集成电路(ASIC，Application Specific Integrated Circuit)或现场可编程门阵列(FPGA，Field-Programmable Gate Array)等实现。

其中，所述处理器配置为运行所述计算机程序时，执行本发明实施例方法的步骤。

配置各网络制式下各载波，对各载波进行混频合路得到合路信号；对合路信号进行处理得到处理后的合路信号，对处理后的合路信号进行分载波，得到处理后的各载波；检测处理后的各载波的功率；在处理后的各载波的功率未落入预设数值范围时，根据处理后的各载波的功率，调整各载波的功率增益，返回至检测处理后的各载波的功率的步骤，在处理后的各载波的功率落入预设数值范围时，各载波的功率定标结束。
