以下结合一示例对链路预均衡补偿过程进行解释说明，但不用于限定本公开实施例的技术方案，本公开示例的技术方案如下：
如图3所示，本公开提供了一种超宽频AAU链路信号平坦度的预均衡补偿的方法，该方法包括以下步骤：
步骤S302，链路射频(例如，下行链路射频)和波控链路离线静态补偿计算(例如，生成补偿表)；
数据链路(如可以为下行数据链路)载波间的平坦度的差异主要是由于射频链路和波控链路在较宽的频谱范围内的射频器件特性带来的，因此通过预先使用矢量网络分析仪、扫描架探头(喇叭天线)采集波控链路器 件的平坦度特性参数(作用同第二不平坦度均衡系数)，使用信号源、频谱仪采集射频链路平坦度特性参数(作用同第一不平坦度均衡系数)，预先生成射频和波控链路离线补偿表，待AAU上建立小区之后，通过读取预先生成的离线补偿表，依据各个载波的实际的功率大小，以及运用平坦度补偿算法，可获取各个有效子载波的补偿系数。
在一示例性实施例中，波控链路平坦度特性参数的采集，可针对这段链路上主要器件，如赋形芯片，功分器进行采集。
离线补偿表，可采用普通文本文件，或者其他形式的存储格式存储于AAU非掉电丢失的存储器中。在一示例性实施例中，可采用普通文本方式存于AAU整机的Flash中。
特性参数采样步进，可根据实际器件的特性进行灵活选择。采样点之间频点区可以采用拟合算法进行拟合，以保证在全带宽中均有采样数据，在一示例性实施例中，频点特性拟合可采用线性拟合算法。
步骤S304，链路(例如，下行链路)不平坦度预均衡补偿系数及因子计算；
AAU整机在上电后，通过读取预存在FLASH中的射频链路和波控链路特性参数表文件，并进行解析，根据链路上分载波的频点和温度信息为索引，以有效子载波间隔步进大小按线性插值方法得到相应带宽射频和波控链路对应的有效子载波数的不平坦度均衡系数，采用dB直接相加的方式合并分载波射频链路和波控链路的频域不平坦度均衡系数，由此可以获得该链路上所有载波频段的不平坦度值，(由于腔体平坦度的采样点非连续，如果索引频点，落在两个采样点之间，则根据实际情况进行线性拟合)。
对于每个天线，根据获取的分载波不平坦度系数计算最后要补偿的合载波不平坦度系数，然后转线性值，取倒数，求预均衡系数的功率平均值，并做归一化得到预均衡补偿系数，为防止频域饱和，根据预均衡系数的最大值取对数得到预均衡补偿因子。其中，预均衡系数可以理解为一组值，该组值随着分载波带宽和分载波数量的变化而变化，如双载波400M带宽 可以包含6000多个值等，预均衡补偿因子可以为0、1、2等数值。以上仅为一种示例，在此不作任何限定。
步骤S306，预均衡补偿系数及因子数据传送和动态补偿；
根据计算获知的通道合载波预均衡补偿系数和因子，提取出各个分载波预期均衡补偿系数和补偿因子，通过XC接口/CPRI/eCPRI接口将其送至基带单元频域处理。每次AAU切换频点时均会做预均衡补偿，从而保证在整个带宽内信号的平坦度。
步骤S308，预调整信号平坦度基带侧补偿生效；
基带单元收到载波预期均衡补偿系数和补偿因子后，在频域按照载波预期均衡补偿系数和补偿因子在有效子载波内作频域相乘、K值缩放对载波平坦度进行调整，该方案平坦度均衡与校准补偿分离，无须复杂的均衡电路，容易实现，降低了系统的复杂度。
通过本实施例，取得了AAU链路预均衡精细化补偿进步，达到了改善链路信号的平坦度效果，节省了射频均衡器件，提高了系统的射频性能以及AAU的空口能力等。
需要说明的是，如图4所示，上述超宽频AAU链路信号平坦度的预均衡补偿的方法可应用于超宽频AAU链路信号平坦度的预均衡补偿的装置中，该装置包括：基带单元、数模转换器、数字上变频、功率放大器、射频本振、数字下变频，波控板(即图4中的天线板)、传输模块，其中，波控板包括功分器、赋形阵子和耦合阵子，波控板通过反馈链路与数字下变频和功率放大器连接。
以下结合另一示例对链路预均衡补偿过程进行解释说明，但不用于限定本公开实施例的技术方案，本公开示例的技术方案如下：
步骤1，链路射频和天线板离线静态补偿表生成；
对超宽频AAU射频链路在其所支持的全频段内，以20M步进，用信 号源+频谱仪对其平坦度特性进行实际扫描，形成射频链路全带宽扫描频点和其平坦度的映射关系表，作为射频链路的特性参数，以文本的形式写入射频板所在整机上FLSAH中。
如图4所示，AAU波控链路上不具备反馈通道，此段链路在较宽频谱范围内的射频器件特性也会带来载波间的平坦度差异，因此预先使用矢量网络分析仪+扫描架探头(喇叭天线)采集器件的平坦度特性参数，采集方法如图5所示，生成波控链路的特性参数，作为波控链路的特性参数，以文本的形式写入波控板所在整机上FLSAH中。
步骤2，链路不平坦度预均衡补偿系数及因子计算；
AAU整机在上电后，通过读取预存在FLASH中的射频链路和波控链路特性参数表文件，并进行解析，根据链路上载波的频点和温度信息为索引，以5G高频有效子载波间隔120K步进大小按线性插值方法得到相应带宽对应的有效子载波数(以单载波400M带宽为例，400M带宽对应3168个有效子载波)的不平坦度系数，采用dB直接相加的方式合并分载波射频链路和波控链路的频域不平坦度均衡系数，以此可以获得该链路上所有载波频段的不平坦度值。
对于每个天线，根据获取的分载波不平坦度系数计算最后要补偿的合载波不平坦度系数，然后转线性值，取倒数，求预均衡系数的功率平均值，并做归一化得到预均衡补偿系数，为防止频域饱和，根据预均衡系数的最大值取对数得到预均衡补偿因子。
步骤3，预均衡补偿系数及因子数据传送和动态补偿；
根据计算获知的通道合载波预均衡补偿系数和因子，提取出各个分载波预期均衡补偿系数和补偿因子，(如果是低载波，提取前3168个有效子载波预均衡补偿系数和因子；如果是高载波，提取后3168个有效子载波预均衡补偿系数和因子。)如果是基带业务上移场景通过XC接口将其传送至AAU基带单元的频域，如果是非基带业务上移场景通过CPRI/eCPRI接口将其传送至BBU基带单元频域。当AAU切换小区频点时均会做预均 衡补偿，从而保证在整个带宽内信号的平坦度。
步骤4，预调整信号平坦度基带侧补偿生效；
基带单元收到载波预期均衡补偿系数和补偿因子后，在频域按照载波预期均衡补偿系数和补偿因子在有效子载波内作频域相乘、K值缩放对载波平坦度进行调整。
综上，通过上述方案进行平坦度均衡与校准补偿分离，无须复杂的均衡电路，容易实现，降低了系统的复杂度。
