Description

一种DPD参数信息的性能评估方法、装置及系统
本申请要求于2022年04月01日提交国家知识产权局、申请号为202210348914.1、申请名称为“一种DPD参数信息的性能评估方法、装置及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信领域，尤其涉及一种数字预失真(digital predistortion，DPD)参数信息的性能评估方法、装置及系统。
背景技术
在无线通信场景中，网络设备在很多情况下需要作为发射端，向作为接收端的终端设备远距离传输信号。而功率放大器(power amplifier，PA)是发射端实现远距离传输信号的核心器件，它可以将发射端产生的低功率信号放大至可进行远距离传输的功率水平。但是，在进行功率放大时，PA会引入非线性失真，导致发送信号的性能指标发生恶化，而数字预失真DPD技术是提升PA输出信号线性度的有效手段，其基本原理是在功率放大前对信号进行数字预处理，提升PA输出信号线性度。
目前，发射端需要在发射端的数字通道处通过获取PA对应的DPD参数来调节PA输出的信号。发射端可以通过两种方式获取到包含DPD参数的DPD参数信息，一种方式是在发射机设计PA后反馈回路，并通过反馈信号获取DPD参数信息，另外一种方式是接收端设备获取DPD参数信息，并将其反馈至发射端。
但是，发射端获取的DPD参数信息对应的性能可能并不理想，例如在获取接收端反馈的DPD参数信息的方案中，由于接收端接收到的信号可能遭受信道非理想以及干扰噪声等恶化因素，导致出现接收端计算得到的DPD参数存在较大误差，即接收端反馈给发射端的DPD参数的性能较差的情况。而目前发射端无有效手段判断获取的DPD参数信息对应的性能，因此发射端根据获取的DPD参数信息调整发射配置时，可能出现发射端性能的提升有限，甚至可能出现恶化发送端性能的情况。

具体实施方式
为了便于理解本申请实施例的技术方案，首先给出本申请涉及的相关技术的简要介绍如下。
PA是无线传输发射机实现远距离信号传输的核心器件，它可以将发射端产生的低功率信号放大至可进行远距离传输的功率水平。但是，在进行功率放大时，PA会引入非线性失真，导致发送信号的性能指标发生恶化。例如，PA引入的非线性失真可导致发送信号的误差向量幅度(error vector magnitude，EVM)与邻道泄露比(adjacent channel leakage ratio，ACLR)的性能下降。DPD技术是提升PA输出信号线性度的有效手段，其基本原理是在功率放大前对信号进行数字预处理，提升PA输出信号线性度，减少PA引入的非线性失真，从而提高PA的效率或输出功率。理论上，DPD对应函数应为PA响应函数的反函数。为了便于理解，DPD技术的基本原理如图1所示，在PA前增加DPD模块，DPD模块可以对输入DPD模块的信号执行DPD(或者说进行DPD处理)来补偿PA的非线性特征，从而使PA输出的信号呈线性。
目前，发射端需要在发射数字通道处通过获取PA对应的DPD参数信息(或者说DPD系数信息)来执行DPD。其中，DPD参数信息可用来表征约定的模型(实现约定和/或协议约定和/或空口交互)的特征，发射端装置可以通过约定的模型以及DPD参数信息确定如何执行DPD。例如，协议规定采用多项式模型、记忆多项式或广义记忆多项式模型等多项式模型来执行DPD，则DPD参数信息可以是上述约定的多项式模型的系数。又例如，协议规定采用神经网络(neural network,NN)模型等深度学习(deep learning,DL)模型来执行DPD，则DPD参数信息可以是神经网络的深度，宽度，连接关系，以及权值等信息。
下面以约定的模型为记忆多项式模型为例，对DPD参数信息加以简要介绍。将输入DPD模块的信号记为s[n]，DPD模块输出的信号记为x[n]，假设配置在DPD模块中的用于执行DPD的约定模型为记忆多项式模型，则x[n]满足如下关系：
x[n]＝∑m∑kck,m|s[n-m]|ks[n-m]；                公式(1)
其中，ck,m表示对应该记忆多项式模型的参数信息，k为该记忆多项式模型的阶次数，m为该记忆多项式模型的记忆深度。k与m的取值范围可以由协议约定和/或空口配置。
以下介绍如何获取DPD参数信息。传统的方案中，发射端需要获取输入PA前的信号(简称为PA前信号)和PA输出的信号(简称为PA后信号)，并根据预设的算法，计算或估计出DPD参数信息。具体地，发射端可以直接在数字通道(数字模块)处获取PA前信号，而对于PA后信号，在一些场景下(例如低频场景)，发射端可以通过PA对应的反馈通道采集PA后信号。
以下以图2所示的场景为示例，对获取DPD参数信息的过程进行介绍，如图2所示，在发射端具有多个数字通道，每个数字通道分别对应一个PA的场景中，每个PA可以具有独立的反馈通道。在数字通道处，模型提取(model extraction)模块可以获取输入数模转换器(digital-to-analog converter，DAC)前的PA前信号，以及从PA对应的独立反馈通道处获取PA后信号。model extraction模块可以根据获取的PA前信号以及PA后信号，以及预设的算法计算得到PA对应的DPD参数信息，再根据获取的DPD参数信息配置对应的DPD模块，以此类推，发射端可以通过每个DPD模块独立地实现对每个PA的DPD补偿。当然，对于发射端具有单个数字通道的场景，且单个数字通道对应一个PA的场景，该独立进行DPD补偿的方法同样适用。
但是，在高频场景中，发射端可能会采用一个数字通道对应多个PA的架构，例如混合波束成型(hybridbeamforming，HBF)架构或者模拟波束成型(analog beamforming，ABF)架构，如图3所示，为一种示例性的采用HBF架构的发射端的示意图。在这种一个数字通道对应多个PA的场景中，发射端分别获取每个PA对应的独立DPD参数信息的代价较大，且即使可以获取各个PA对应的独立DPD参数信息，因为DPD需要在数字通道处实现(例如图3中的中频模块)，一个数字通道上配置的一个DPD模块也无法实现分别补偿对应的多个PA。
因此，目前提出了一种基于接收端的DPD参数信息获取方案，该方案基于空口DPD(overthe air-DPD，OTA-DPD)技术，其基本原理为：发射端处一个数字通道对应的信号经过多个PA发射到接收端后，对于接收端而言，接收到的多个PA的合成信号可以等效为一个PA所输出的信号。换言之，对于接收端而言，接收到的多个PA的合成信号的非线性效应可以等效为单个PA输出信号的非线性效应。因此，接收端可以根据接收到的信号获取DPD参数信息。示例性地，如图4所示，接收端处的信号重建(signal reconstruction)模块可以恢复出发射端处DAC前的信号(PA前信号)，model extraction模块可以获取接收端接收到的信号(简称为接收信号)进行模数转换后的数字信号，以及从signal reconstruction模块获取到的PA前信号。因为多个PA所对应的接收信号可以等效为一个PA所对应的接收信号，所以model extraction模块可以根据获取的接收信号以及PA前信号，以及预设的算法确定出DPD参数信息，且确定的DPD参数信息可以用于补偿这多个PA的非线性效应，使得 接收信号的非线性得到纠正。根据上述结论，发射端可以在单个数字通道处，根据接收端反馈的DPD参数信息，对这单个数字通道对应的所有PA的非线性效应进行补偿，从而保证接收端接收的信号的质量。当然，这种方案不仅可以应用于一个数字通道对应多个PA的场景中，在一个数字通道对应一个PA的场景中，该方案同样适用。
但是，这种方案存在以下问题：由于接收端接收到的信号可能遭受信道非理想以及干扰噪声等因素的恶化，因此接收端根据接收到的信号确定的DPD参数信息可能存在可靠度不稳定的情况，换言之，可能出现接收端反馈给发射端的DPD参数的性能(或者说质量)较差的情况。例如，当接收端遭受到突发干扰后，其确定的DPD参数信息可能存在较大误差。而发射端无有效手段判断接收端反馈的DPD参数信息对应的性能，因此发射端根据接收端反馈的DPD参数调整发射配置(发射参数)时，可能出现发射端性能的提升有限，甚至可能出现恶化发送端性能的情况。基于此，本申请实施例提供一种DPD参数信息的性能评估方法，用于解决发射端无法判断获取的DPD参数的质量的问题。

下面将结合图1至图6，以图5a或图5b所示的发射端装置20与任一接收端装置30进行交互为例，对本申请实施例提供的DPD参数信息的性能评估方法进行展开说明，其中，为了展开说明时语义清楚，下文将该接收端装置30称为第一接收端装置。如图7所示，该DPD参数信息的性能评估方法包括S701-S702：
S701、发射端装置获取第一DPD参数信息。
S702、第一接收端装置向发射端装置发送性能指标信息。相对应的，发射端装置接收来自第一接收端装置的性能指标信息，性能指标信息用于表征第一性能指标，第一性能指标为根据第一DPD参数信息对第一信号执行DPD后得到的性能指标。
需要说明的是，本申请实施例并不限定S701和S702的时序顺序。S701可以在S702之前执行，或者，S701可以和S702在同一时间执行，或者，S701可以在S702之后执行，
图7所示的时序顺序仅为一种示例。
本申请实施例中，发射端装置具有一个或多个数字通道(或天线端口，下文中数字通道均可替换为天线端口或端口)，其中每个数字通道对应一个或多个PA，每个 PA对应一个或多个发射天线。其中，每个数字通道对应一个发送信号，发射端装置可以向第一接收端装置发送该发送信号。具体地，发射端装置处，发送信号在经过数字通道处的DAC前为数字信号，经过DAC后为模拟信号，并通过模拟通道输入对应的一个或多个PA进行功率放大，每个PA输出的放大信号由对应的一个或多个发射天线发射，第一接收端装置可以通过接收天线接收到发射天线发射的信号。可选的，基于发射端装置可能的结构，数字通道对应的发送信号在输入PA进行功率放大前，还可以进行移相等操作。
为了便于理解，以下以发射端装置处的某一数字通道称为第一数字通道，该第一数字通道对应的发送信号称为第一信号为例，对本申请实施例的技术方案进行介绍。示例性的，假设第一数字通道对应多个PA，若发射端装置未对第一信号执行DPD(也可以称为没有对第一信号进行DPD处理)，发射端装置发送第一信号的示意图可以如图8所示。第一信号输入对应的多个PA，PA对输入的第一信号进行功率放大，输出PA放大后的第一信号至对应的发射天线，从而使发射天线发送PA放大后的第一信号。其中，第一信号在输入PA在前，其也可以称为PA前信号，而PA放大后的第一信号则可以称为PA后信号，或者称为发射信号。
示例性的，假设第一数字通道对应多个PA，发射端装置采用DPD参数信息对第一信号执行DPD，并发送第一信号的示意图可以如图9所示。如图9所示，发射端装置根据DPD参数信息对第一信号执行DPD后，DPD补偿后的第一信号(也可以称为DPD处理后的第一信号)输入对应的多个PA，PA对输入的DPD补偿后的第一信号进行功率放大，输出PA放大后的第一信号至对应的发射天线，从而使发射天线发送PA放大后的第一信号。发射端装置根据DPD参数信息对第一信号执行DPD后，可以提升PA放大后的第一信号的线性度。其中，DPD补偿后的第一信号在输入PA前，其也可以称为PA前信号，而PA放大后的第一信号则可以称为PA后信号，或者称为发射信号。
对于S701，第一DPD参数信息包括第一DPP参数，可用于对第一信号进行DPD补偿，换言之，发射端装置可以根据第一DPD参数信息，采用其中的第一DPD参数对第一信号执行DPD，从而补偿第一数字通道对应的PA的非线性特征，提升PA输出的信号的线性度。
本申请实施例中，发射端装置可以通过多种方式获取第一DPD参数信息。以下为列举的示例性的四种方式。
方式一：发射端装置接收来自第一接收端装置的第一DPD参数信息。
方式一中，发射端装置将第一信号发送给第一接收端装置，第一接收端装置可以根据接收到的信号确定第一DPD参数信息。可选的，第一接收端装置根据接收到的信号确定第一DPD参数信息的具体实现可以参考上文对基于接收端的DPD参数信息获取方案的介绍，在此不再赘述。
方式二：发射端装置接收来自第二接收端装置的第一DPD参数信息。
方式二中，第二接收端装置是与第一接收端装置不同的另一接收端装置。发射端装置将第一信号发送给第二接收端装置，第二接收端装置可以根据接收到的信号确定第一DPD参数信息。可选的，第二接收端装置根据接收到的信号确定第一DPD参数 信息的具体实现可以参考上文对基于接收端的DPD参数信息获取方案的介绍，在此不再赘述。
方式三：发射端装置根据预设算法确定第一DPD参数信息。
方式三中，发射端装置自身可以获取第一信号以及第一信号经由PA放大后输出的信号，并根据预设的算法计算出第一DPD参数信息。可选的，发射端装置根据第一信号以及第一信号经由PA放大后输出的信号确定第一DPD参数信息的具体实现可以参考上文对发射端获取DPD参数信息的传统方案的介绍，在此不再赘述。
方式四：发射端装置综合通过多种方式获取到的DPD参数信息得到第一DPD参数信息。可选的，多种方式可以为上述方式一至方式三。
例如，发射端装置可以对第一接收端装置和第二接收端装置分别上报的DPD参数信息进行联合处理，例如进行平均、加权平均或系数拼接等操作，从而获取到第一DPD参数信息。
需要说明的是，上述四种方式中涉及的第一信号为没有根据第一DPD参数信息进行DPD处理的第一信号，也可以称为根据第一DPD参数信息执行DPD前的第一信号。本申请实施例中，可选的，没有根据第一DPD参数信息进行DPD处理的第一信号可以为没有经过DPD处理的第一信号，示例性的，该情况中，第一信号可参考上文对图8的说明。或者，没有根据第一DPD参数信息进行DPD处理的第一信号可以为根据第二DPD参数信息执行DPD后的第一信号，第二DPD参数信息为与第一DPD参数信息不同的参数信息。示例性的，参考图9，假设图9中的DPD模块根据第二DPD参数信息对第一信号执行DPD，若发射端装置采用上述方式三获取第一DPD参数信息，发射端装置可以获取DPD补偿后的第一信号和PA放大后的第一信号来计算第一DPD参数信息，第一DPD参数信息可以用于更新第二DPD参数信息，使DPD模块可以采用更新后的第一DPD参数信息对第一信号进行DPD处理。在此以第一信号为例，统一对没有根据第一DPD参数信息进行DPD处理(或者称为根据第一DPD参数信息执行DPD前)可能包括的情况进行说明，以下不再赘述。
可选的，若发射端装置需要从其他装置获取第一DPD参数信息，则发射端装置可以指示其他装置获取和/或发送第一DPD参数信息的配置。例如，若采用上述方式一获取第一DPD参数信息，在发射端装置接收来自第一接收端装置的第一DPD参数信息之前，发射端装置可以向第一接收端装置发送第三配置信息，第三配置信息用于指示第三时频资源和/或第四时频资源，第一接收端装置接收到第三配置信息后，可以确定第三时频资源并在第三时频资源上获取第一DPD参数信息，和/或确定第四时频资源并在第四时频资源上发送第一DPD参数信息。示例性的，第三时频资源可以为第一接收端装置接收信号的时频资源，第一接收端装置可以在第三时频资源上接收发射装置发射的信号，并根据接收到的信号计算或获取第一DPD参数信息。
对于S702，第一接收端装置可以确定性能指标信息，然后将性能指标信息发送给发送端装置。其中，性能指标信息用于表征第一性能指标，第一性能指标为根据第一DPD参数信息执行DPD后得到的性能指标。因此，发送端装置可以根据接收的性能指标信息，获知若根据第一DPD参数信息执行DPD可以得到的性能指标，从而可以准确判断获取的第一DPD参数的性能信息或者说质量信息，实现准确配置与第一DPD 参数适配的发射参数，达成更大的发射功率或更好的信号发送质量。
以下对S702进行具体的解释说明。
首先，对性能指标信息进行展开介绍。S702中，性能指标信息是第一接收端装置确定的用于表征第一性能指标的信息。可选的，本申请实施例中，第一性能指标可以为发射端装置根据第一DPD参数信息执行DPD后，第一接收端装置得到的性能指标，或者，第一性能指标可以为第一接收端装置根据第一DPD参数信息执行DPD后得到的性能指标。
进一步地，第一性能指标可以为发射端装置根据第一DPD参数信息对第一信号执行DPD后，DPD补偿后的第一信号经由对应的一个或多个PA放大后，第一接收端装置得到的性能指标。示例性的，参考图9，假设图9中的DPD模块根据第一DPD参数信息对第一信号执行DPD，第一性能指标可以为第一接收端装置确定的PA放大后的第一信号的性能指标。
或者，第一性能指标可以为第一接收端装置根据第一DPD参数信息对接收信号执行DPD后，DPD补偿后的接收信号的性能指标。其中，接收信号与第一接收端装置发送的PA放大后的第一信号对应。需要说明的是，该情况中，第一接收端装置发送的PA放大后的第一信号没有根据第一DPD参数信息进行DPD处理。
本申请实施例中，上述第一性能指标的多种定义，将在下文结合确定性能指标信息的具体实现方式进行展开介绍，在此不再展开说明。
可选的，第一性能指标可以是特定信号(上文介绍的用于确定第一性能指标的PA放大后的第一信号或者DPD补偿后的接收信号)在特定波束方向、角度或区域的性能指标。
本申请实施例中，可以得到的性能指标(第一性能指标)可以包括以下信息中的至少一项：
误差向量幅度(error vector magnitude，EVM)、信号干扰噪声比(信干噪比)(signal to interference plus noise ratio，SINR)、信噪比(signal to noise ratio，SNR)、可支持的调制编码方式(modulation and coding scheme，MCS)、信道质量指示(channel quality indicator，CQI)、可支持的最高调制阶数、均方误差(mean squared error，MSE)、归一化均方误差(the normalized mean squared error，NMSE)、邻道泄露比(adjacent channel leakage ratio，ACLR)和零子载波功率。
可以看出，第一性能指标包括的信息可以表征用于表征信号或者信道质量。当然，本申请实施例并不限定第一性能指标仅能为上述信息，应理解，根据需求或者场景的不同，第一性能指标还可以包括其他信息。另外，若出现新定义的可用于表征信号或信道质量的信息，第一性能指标还可以包括这些新定义的信息，本申请实施例的技术方案依然可以应用。
本申请实施例中，性能指标信息可以包括以下至少一项：
第一性能指标信息和第二性能指标信息。
其中，第一性能指标信息用于表征第一性能指标的数值，换言之，第一性能指标信息用于表征根据第一DPD参数信息执行DPD后得到的性能指标的数值。基于本方案，若性能指标信息包括第一性能指标信息，发射端装置可以根据第一性能指标信息， 直接确定若根据第一DPD参数信息进行DPD补偿所能达到的性能指标的数值，从而判断第一DPD参数信息的质量。
示例性的，参考图9，假设图9中的DPD模块根据第一DPD参数信息对第一信号执行DPD，第一性能指标的数值可以为PA放大后的第一信号的性能指标的数值，例如第一性能指标信息可以包括PA放大后的第一信号的EVM、SNR、CQI和MSE的数值信息。
进一步地，为了使发射端装置可以更准确地确定根据第一DPD参数信息执行DPD所能得到的性能增益，本申请实施例还定义了第二性能指标信息，第二性能指标信息用于表征第一性能指标的增益。若性能指标信息包括第二性能指标信息，发射端装置可以根据第二性能指标信息，确定若根据第一DPD参数信息进行DPD补偿所能带来的性能指标的提升，从而判断第一DPD参数信息的质量。
一种可能的实现方式中，第二性能指标信息包括第一性能指标的数值信息和第二性能指标的数值信息，第二性能指标为根据第一DPD参数信息执行DPD前(或者说，没有根据第一DPD参数进行DPD处理)的性能指标。
进一步地，第二性能指标可以为发射端装置没有根据第一DPD参数信息进行DPD处理的第一信号(也可以称为根据第一DPD参数执行DPD前的第一信号)经由对应的一个或多个PA放大后的性能指标。示例性的，参考图8，第一性能指标可以为PA放大后的第一信号的性能指标。
或者，第二性能指标可以为第一接收端装置接收到的信号的性能指标。其中，第一接收端装置接收到的信号与发射端装置发送的PA放大后的第一信号对应。需要说明的是，该情况中，发射端装置发送的PA放大后的第一信号没有根据第一DPD参数信息进行DPD处理。
本申请实施例中，上述第二性能指标的多种定义，将在下文结合确定性能指标信息的具体实现方式进行展开介绍，在此不再展开说明。
可选的，第二性能指标可以是特定信号(上文介绍的用于确定第二性能指标的PA放大后的第一信号或者接收到的信号)在特定波束方向、角度或区域的性能指标。
本申请实施例中，第二性能指标包括的信息与第一性能指标包括的信息呈一一对应关系。该实现方式中，发射端装置可以比较第一性能指标的数值信息和第二性能指标的数值信息，从而得到根据第一DPD参数信息进行DPD补偿的前后性能指标的变量信息(包括增加量或者降低量)，进而得到根据第一DPD参数信息进行DPD补偿所能带来的性能指标增益。
示例性的，该实现方式中，若第一性能指标为根据第一DPD参数信息对第一信号执行DPD后得到的性能指标，第二性能指标为根据第一DPD参数信息对第一信号执行DPD前的性能指标，第二性能指标信息可以包括以下信息：根据第一DPD参数信息进行DPD补偿前后，PA放大后的第一信号的EVM的数值信息、根据第一DPD参数信息进行DPD补偿前后，PA放大后的第一信号的SNR的数值信息、根据第一DPD参数信息进行DPD补偿前后，PA放大后的第一信号的CQI的数值信息、根据第一DPD参数信息进行DPD补偿前后，PA放大后的第一信号的MSE的数值信息。
需要说明的是，本申请实施例中，DPD补偿前或者DPD补偿后中的“前”或者“后”， 指时序上的前或者后，并不是指发射端装置的电路结构中信号所处的具体位置。例如DPD补偿前信号指未采用DPD参数信息进行DPD处理的信号，DPD补偿后信号指已采用DPD参数信息进行DPD处理的信号。
另一种可能的实现方式中，第二性能指标信息为第一性能指标的数值信息相比于第二性能指标的数值信息的变量信息(包括增加量或者降低量)。该实现方式中，发射端装置可以根据第一性能指标的数值信息相比于第二性能指标的数值信息的变量信息，直观确定出根据第一DPD参数信息进行DPD补偿所能带来的性能指标增益。
需要说明的是，根据性能指标的不同，有些第一性能指标的数值信息相比于第二性能指标的数值信息的增加量可以用于表征性能指标的增益，有些第一性能指标的数值信息相比于第二性能指标的数值信息的降低量可以用于表征性能指标的增益。示例性的，若第一性能指标为EVM,EVM的数值的降低量(线性比值或dB值)为性能指标的增益。若第一性能指标为SINR或SNR，SINR或SNR的增加量(线性比值或dB值)为性能指标的增益。若第一性能指标为CQI，CQI的增加量(阶数增量)为性能指标的增益。若第一性能指标为MSE或者NMSE，MSE或NMSE的降低量(线性比值或dB值)为性能指标的增益。
示例性的，性能指标信息包括第一性能指标信息和第二性能指标信息时，若第二性能指标信息为第一性能指标的数值信息相比于第二性能指标的数值信息的变量信息，第一性能指标为根据第一DPD参数信息对第一信号执行DPD后得到的性能指标，第二性能指标为根据第一DPD参数信息对第一信号执行DPD前的性能指标，性能指标信息可以包括以下信息：根据第一DPD参数信息进行DPD补偿后，PA放大后的第一信号的EVM的数值信息和(相比于根据第一DPD参数信息进行DPD补偿前，PA放大后的第一信号的)EVM的降低量、根据第一DPD参数信息进行DPD补偿后，第一信号的SNR的数值信息和SNR的增加量、根据第一DPD参数信息进行DPD补偿后，PA放大后的第一信号的CQI的数值信息和CQI的增加量、根据第一DPD参数信息进行DPD补偿后，PA放大后的第一信号的MSE的数值信息和MSE的降低量、根据第一DPD参数信息进行DPD补偿后，PA放大后的第一DPD补偿后信号的NMSE的数值信息和NMSE的降低量。
可选的，性能指标信息包括第二性能指标信息，且第二性能指标信息为第一性能指标的数值信息相比于第二性能指标的数值信息的变量信息时，性能指标信息还可以包括第二性能指标的数值信息。发射端装置可以根据第二性能指标信息和第二性能指标的数值信息，确定根据第一DPD参数进行DPD补偿前性能指标的数值和若根据第一DPD参数信息进行DPD补偿所能带来的性能指标的提升，从而判断第一DPD参数信息的质量。
示例性的，性能指标信息包括第一性能指标的数值信息相比于第二性能指标的数值信息的变量信息，以及第二性能指标的数值信息时，若第一性能指标为根据第一DPD参数信息对第一信号执行DPD后得到的性能指标，第二性能指标为根据第一DPD参数信息对第一信号执行DPD前的性能指标，性能指标信息可以包括以下信息：根据第一DPD参数信息进行DPD补偿前，PA放大后的第一信号的EVM的数值信息和根据第一DPD参数信息进行DPD补偿后，PA放大后的第一信号(相比于根据第一DPD 参数信息进行DPD补偿前，PA放大后的第一信号)的EVM的降低量、根据第一DPD参数信息进行DPD补偿前，PA放大后的第一信号的SNR的数值信息和根据第一DPD参数信息进行DPD补偿后，PA放大后的第一信号的SNR的增加量、根据第一DPD参数信息进行DPD补偿前，PA放大后的第一信号的CQI的数值信息和根据第一DPD参数信息进行DPD补偿后，PA放大后的第一信号的CQI的增加量、根据第一DPD参数信息进行DPD补偿前，PA放大后的第一信号的MSE/NMSE的数值信息和根据第一DPD参数信息进行DPD补偿后，PA放大后的第一信号的MSE/NMSE的降低量。
上文介绍了性能指标信息，以下介绍本申请实施例中，第一接收端装置如何确定性能指标信息。
实现方式一：第一接收端装置可以根据第一DPD参数信息和预设算法计算得到第一性能指标中至少一项对应的性能指标信息。
该实现方式中，第一性能指标可以理解为第一接收端装置推测的发射端装置若根据第一DPD参数信息执行DPD后可以得到的性能指标。具体地，第一接收端装置可以根据第一DPD参数信息和预设算法，计算出若根据第一DPD参数信息对接收信号执行DPD可以得到的信号，并将计算出的信号推测为发射端装置根据第一DPD参数信息对第一信号进行DPD补偿后，PA放大后的第一信号，即发射天线上的发射信号，从而将该计算出的信号的性能指标的数值信息确定为对应的第一性能指标的数值信息。其中，接收信号与发射端装置发送的PA放大后的第一信号对应，需要说明的是，该情况中，发射端装置发送的PA放大后的第一信号没有根据第一DPD参数信息进行DPD处理。
该实现方式中，第一接收端装置根据第一DPD参数信息，计算出若对接收信号执行DPD处理可以得到的信号，也可以理解为第一接收端装置根据第一DPD参数信息对接收信号执行数学意义上的DPD处理，所以该实现方式中，第一性能指标也可以理解为第一接收端装置根据第一DPD参数信息执行DPD处理后得到的性能指标。
示例性的，假设第一DPD参数信息对应的，用于执行DPD的DPD等效函数为g(·),发射端装置处多功放对应的等效函数为f(·),发射端装置处的第一信号为x(t),第一接收端装置接收到PA放大后的第一信号f(x(t)),则第一接收端装置可以根据DPD等效函数g(·)推测出，发射端装置对第一信号执行DPD后的得到的DPD补偿后的第一信号为z(t)＝g(x(t)),DPD补偿后的第一信号经过多PA后的叠加信号为y(t)＝f(z(t))＝f(g(x(t)))。其中，y(t)的性能指标即为推测的发射端装置根据第一DPD参数信息执行DPD后可达到的性能指标。例如，第一性能指标包括EVM时，第一接收端装置可以将y(t)的EVM确定为第一性能指标的数值信息。
上文介绍的第一性能指标可能包括的多项信息中，EVM,ACLR以及可支持的最高调制阶数可适用于该实现方式。
实现方式二：第一接收端装置可以根据第一DPD参数信息和第一时频资源进行测量，得到第一性能指标中至少一项对应的性能指标信息。
该实现方式中，第一接收端装置可以根据第一DPD参数信息，在某一时频资源上对接收到的信号执行DPD处理得到特定信号，并测量该特定信号确定第一性能指标中至少一项对应的性能指标信息。该实现方式中，第一性能指标可以理解为第一接收端 装置根据第一DPD参数执行DPD后得到的性能指标。其中，用于获取性能指标信息的接收信号对应的时频资源可以称为第一时频资源。
具体地，发射端装置可以向第一接收端装置发送第一信号，而第一接收端装置接收到与第一信号对应的第四信号后，可以根据第一DPD参数信息对接收到的第四信号进行处理，得到第三信号，然后获取第三信号对应的性能指标，并将获取得到的性能指标确定为对应的第一性能指标的数值信息。其中，发射端装置发送的第一信号是PA放大后的第一信号，且该情况中，发射端装置发送的PA放大后的第一信号没有根据第一DPD参数信息进行DPD处理。
可选的，在某些场景中，第一接收端装置可以将该实现方式中得到的特定信号等效为发射端装置根据第一DPD参数信息对第一信号执行DPD后得到的发射信号。因此，在某些场景中，第一接收端装置测量该特定信号得到的性能指标可以用于表征(或者隐式表征)发射端装置根据第一DPD参数信息对第一信号执行DPD后，PA放大后的第一信号的性能指标，即第一性能指标。
示例性地，假设第一DPD参数信息对应的，用于执行DPD的DPD等效函数为g(·)，发射端装置向接收端装置发送第一信号后，第一接收端装置接收到的信号为r(t),第一接收端装置根据DPD等效函数g(·)，对r(t)进行处理得到信号u(t)＝g(r(t))。第一接收端装置可获取u(t)对应的性能指标来确定对应的性能指标信息，例如第一性能指标包括MSE、EVM、SNR时，第一接收端装置可以将测量u(t)得到的MSE、EVM、SNR确定为第一性能指标的数值信息。在上述示例将接收信号以及对应的处理后信号记为模拟形式，即r(t)和u(t)。应理解，第一接收端装置也可以在数字域处理上述信号，则接收信号以及对应的处理后信号可记为r(n)和u(n)，其中u(n)＝g(r(n))。
上文介绍的第一性能指标可能包括的多项信息(EVM、SINR、SNR、MCS、CQI、可支持的最高调制阶数、MSE、NMSE、ACLR和零子载波功率)均可适用于该实现方式。
本申请实施例中，上文介绍的实现方式一和实现方式二可以用于确定第一性能指标的数值信息，而第一接收端装置在确定性能指标信息时，若需要确定第二性能指标的数值信息，例如性能指标信息包括用于表征第一性能指标的增益的第二性能指标信息，第一接收端装置需要确定第一性能指标的数值信息和第二性能指标的数值信息，第一接收端装置确定第二性能指标的数值信息的实现方式也可以参考上述实现方式一和实现方式二。
在实现方式一中，第一接收端装置可以根据接收信号获取第二性能指标的数值信息。例如，在实现方式一的示例的场景中，第一接收端装置可以将第一信号x(t)经过多PA后的叠加信号f(x(t))的性能指标的数值信息确定为第二性能指标的数值信息。
在实现方式二中，第一接收端装置可以根据接收信号(第四信号)，获取第二性能指标的数值信息。例如，在实现方式二的示例场景中，第一接收端装置可以测量接收到的信号r(t)或者r(n)的性能指标，并将获取到的性能指标的数值确定为第二性能指标的数值信息。可选的，在某些场景中，第一接收端装置可以将第四信号等效为发射端装置根据第一DPD参数信息执行DPD前，PA放大后的第一信号，因此，在某些场景中，第一接收端装置测量第四信号得到的性能指标可以用于表征(或者隐式表征)发射端装置 根据第一DPD参数信息执行DPD前，PA放大后的第一信号的性能指标。
可选的，本申请实施例中，第一接收端装置可以在同一时频资源上获取第一性能指标的数值信息和第二性能指标的数值信息。该方案中第一接收端装置采用相同的资源获取DPD补偿前后性能指标的数值信息，可以排除信道衰落和干扰等外部因素的影响，保证得到的第一性能指标的增益信息可以准确体现根据第一DPD参数信息进行DPD补偿所能带来的增益。或者，第一接收端装置可以在不同的时频资源上分别获取第一性能指标的数值信息和第二性能指标的数值信息。该方案中第一接收端装置采用不同的资源获取DPD补偿前后性能指标的数值信息，可以降低第一接收端装置的处理复杂度。
另外，从上文的介绍可知，若采用上述两种实现方式：实现方式一和实现方式二，第一接收端装置均需要先获取第一DPD参数信息来确定性能指标信息。以下介绍第一接收端装置如何获取第一DPD参数信息：
可选的，第一接收端装置可以根据预设的算法，自身确定第一DPD参数信息，具体可以参考上文对发射端装置获取第一DPD参数信息的方式一的介绍。
或者，第一接收端装置可以接收来自发射端装置的第一DPD参数信息。其中，发射端装置发送的第一DPD参数信息可以是发射端装置自身确定的，也可以是发射端装置从其余装置(例如第二接收端装置)处获取的，具体可以参考上文对发射端装置获取第一DPD参数信息的方式二、方式三或方式四的介绍。
上文介绍的实现方式一和实现方式二中，第一性能指标为第一接收端装置根据第一DPD参数执行DPD后得到的性能指标。此外，本申请实施例还提供一种第一接收端装置无需获取第一DPD参数信息，也可以确定性能指标信息的方案，即下文介绍的实现方式三：
该实现方式中，发射端装置可以将第二信号发送给第一接收端装置，第一接收端装置接收第二信号，将第二信号的性能指标确定为第一性能指标，测量第二信号，从而确定第一性能指标中至少一项对应的性能指标信息。其中，第二信号为发射端装置根据第一DPD参数信息对第一信号执行DPD后，DPD补偿后的第一信号经由对应的PA放大后得到的信号。示例性的，参考图9，假设DPD模块根据第一DPD参数信息对第一信号进行DPD处理，发射端装置发送的第二信号可以为PA放大后的第一信号。该实现方式中，第一接收端装置根据接收的第二信号确定第一性能指标，而第二信号是发射端装置根据第一DPD参数信息对第一信号执行DPD后得到的，因此第一性能指标可以理解为发射端装置根据第一DPD参数信息执行DPD后，第一接收端装置得到的性能指标。
具体地，第一接收端装置在接收到第二信号后，可以在某一时频资源上测量第二信号，并根据测量得到的性能指标的数值确定为第一性能指标的数值，从而确定第一性能指标信息。
或者，该实现方式中，发射端装置可以将第一信号和第二信号发送给第一接收端装置，第一接收端装置接收第一信号和第二信号，将第一信号的性能指标作为第二性能指标，将第二信号的性能指标作为第一性能指标，测量第一信号和第二信号，从而确定第一性能指标中至少一项对应的性能指标信息。其中，发射端装置发送的第一信 号是采用第一DPD参数进行DPD补偿前，PA放大后的第一信号。示例性的，参考图8，发射端装置发送的第一信号可以为PA放大后的第一信号。
具体地，第一接收端装置接收到第一信号和第二信号后，分别在不同的时频资源上测量第一信号和第二信号，并将测量第一信号得到的性能指标的数值确定为第二性能指标的数值，将测量第二信号得到的性能指标的数值确定为第一性能指标的数值，从而可以根据第一性能指标的数值和第一性能指标的数值确定第二性能指标信息。
上文介绍的第一性能指标可能包括的多项信息(EVM、SINR、SNR、MCS、CQI、可支持的最高调制阶数、MSE、NMSE、ACLR和零子载波功率)均可适用于该实现方式。
可选的，上文介绍的第一接收端装置确定性能指标信息的三种实现方式可以相互结合应用，也可以仅应用一种实现方式。例如，第一性能指标包括EVM,ACLR、MSE、SNR时，第一接收端装置可以通过实现方式一获取EVM,ACLR对应的性能指标信息，并通过实现方式二获取MSE、SNR对应的性能指标信息。或者，第一接收端装置也可以通过实现方式三获取EVM,ACLR、MSE、SNR对应的性能指标信息。

在发射端装置接收来自第一接收端装置的性能指标信息之前，发射端装置向第一接收端装置发送第一配置信息，第一配置信息用于指示第一时频资源，第一时频资源用于第一接收端装置获取性能指标信息。该方案中，发射端装置可以指示用于第一接收端装置获取性能指标信息的时频资源，例如上文介绍的实现方式二中，用于第一接收端装置进行测量得到性能指标信息的第一时频资源。

可选的，第二配置信息可以包括第二时频资源信息，第二时频资源为第一接收端装置发送性能指标信息所需的时频资源。第一接收端装置可以根据第二配置信息，确定在第二时频资源上发送性能指标信息。
可选的，第二配置信息可以包括第一指示信息，第一指示信息用于指示第一接收端装置所需发送的第一性能指标。例如，第一指示信息可以指示第一接收端装置需要发送的第一性能指标包括EVM、SNR、CQI，第一接收端装置可以根据第一指示信息，从获取性能指标信息中，选择EVM、SNR、CQI对应的性能指标信息发送给发射端装置。
需要说明的是，本申请实施例中，若均由第一接收端装置获取第一DPD参数信息以及性能指标信息，用于第一接收端装置获取第一DPD参数信息的资源和用于第一接收端装置获取性能指标信息的资源，可以为不同的资源，也可以为相同的资源。用于第一接收端装置发送性能指标信息的资源和用于第一接收端装置发送性能指标信息的资源，可以为不同的资源，也可以为相同的资源。
示例性的，如图10所示，假设均由第一接收端装置获取第一DPD参数信息以及性能指标信息，将用于第一接收端装置获取性能指标信息的时频资源称为第一时频资源，将用于第一接收端装置发送性能指标信息的时频资源称为第二时频资源，将用于第一接收端装置获取第一DPD参数信息的时频资源称为第三时频资源，将用于第一接收端装置发送第一DPD参数信息的时频资源称为第四时频资源。如情况一所示，第一时频资源和第三时频资源可以为同一时频资源，第二时频资源和第四时频资源可以为同一时频资源。如情况二所示，第一时频资源和第三时频资源可以为不同的时频资源，第二时频资源和第四时频资源可以为同一时频资源。如情况三所示，第一时频资源和第三时频资源可以为相同的时频资源，第二时频资源和第四时频资源可以为不同的时频资源。如情况四所示，第一时频资源、第二时频资源、第三时频资源和第四时频资源可以分别为不同的时频资源。
可选的，本申请实施例中，第一接收端装置在向发射端装置发送性能指标信息时，可以将性能指标信息与以下至少一项信息关联发送给发射端装置：用于第一接收端装置获取性能指标信息的时频资源的信息，可以称为第一时频资源信息，和第一DPD参数信息。其中，性能指标信息关联于第一DPD参数信息可以表示该上报的性能指标信息是采用了该第一DPD参数信息后达到或者能期望达到的性能指标。性能指标信息关联于第一时频资源信息可以表示该上报的性能指标信息是在该第一时频资源上测量或获取到的。
可选的，在S702之后，本申请实施例提供的DPD参数信息的性能评估方法还可以包括S703：发射端装置根据性能指标信息，确定发射端装置的发射参数。

可选的，发射端装置根据性能指标信息确定发射端装置的发射参数可以包括：
发射端装置根据性能指标信息，确定发射端装置是否采用第一DPD参数信息。例如，如果性能指标信息不满足预设条件，则发射端装置不根据第一DPD参数信息执行DPD，如果性能指标信息满足预设条件，则发射端装置根据第一DPD参数信息执行DPD。其中，预设条件可以根据需求配置。基于本方案，发射端装置可以根据性能指标信息确定发射端装置是否应该根据第一DPD参数信息来执行DPD，可以在第一DPD参数信息质量不佳时不根据第一DPD参数信息执行DPD，避免出现因为第一DPD参数信息质量差而导致的性能提升小甚至恶化的情况。
可选的，在由多个第一接收端装置分别获取并发送性能指标信息，发射端装置接收到多个性能指标信息的情况下，发射端装置根据性能指标信息确定发射端装置的发射参数包括：
发射端装置根据多个性能指标信息，从多个性能指标信息分别对应的多个第一DPD参数信息中，选择目标DPD参数。具体地，发射端装置可以比较接收到的多个性能指标信息分别表征的第一性能指标，在多个性能指标信息分别对应的多个第一DPD参数信息中，选择一个第一DPD参数信息作为目标DPD参数信息，并根据目标DPD参数信息执行DPD。例如，发射端装置可以根据多个第一DPD参数信息分别对应的第一性能指标，选择质量或者说性能最好的第一DPD参数信息作为目标DPD参数信息。从而使发射端装置根据目标DPD参数信息执行DPD后，可以获取到最高的性能提升。
