实施例3
本实施例是根据本发明的可选实施例，用于结合具体场景对本申请进行详细说明：
本实施例为NB_IOT制式下3.75k子载波自动化无线指标测试方法。该方法利用灌入信号源NB-IOT制式的上行信号，由基站进行接收来完成无线指标测试。由于一般信号源只能支持和网络侧10ms时钟对齐，无法直接进行NB_IOT制式下上行NB-PUSCH信道的3.75k子载波单个RU为32ms周期信号的指标测试，同样的也无法直接对NB-PRACH信号，单次重复为5.6ms周期信号的指标测试。本发明提出了一种方法可以完成NB_IOT制式下上行NB-PUSCH信道和NB-PRACH信道的自动化无线指标测试。
本实施例包括：
第一步，需要通过复制信号源的方法产生10ms周期整数倍的信号，对于3.75k的NB-PUSCH信道，每个RU为32ms的信号，则需要产生(RU*重复次数*5*32)ms信号，例如：对于1个RU 1次重复的32ms信号，需要通过复制5次产生160ms的信号，对于10个RU，128次重复的40960ms信号，需要通过复制5次产生204800ms的信号。对于RRACH信道，根据重复次数构造完成数据源后，通过后面补0的方法补齐到10ms的整数倍，如表1所示：
表1
Figure PCTCN2017103505-appb-000001
第二步，将第一步产生的源信号前面加入10ms的检测头，这10ms的检测头含有特殊扰码的ZC序列信号，网络侧通过不断检测10ms内是否含有特殊扰码的ZC序列信号来找到信号源发送数据的起始位置，进而和信号源发送的起始位置对齐。
第三步，基站侧找到信号源发送的起始位置之后，就可以根据源数据的发送周期和重复次数做正常的信道处理，完成无线指标测试。
整个无线指标测试过程不需要人工参与，生成的信号源保证10ms长度整数倍并加上10ms的头，网络侧利用搜头算法自动完成与信号源发送起始位置的对齐。
本实施例的方法可以利用信号源进行NB_IOT制式下的无线指标测试，并且整个无线指标测试过程不需要人工参与，网络侧自动搜索和信号源发送信号对齐。
本实施例的重点在于：对于NB-PUSCH信道通过复制信号源的方法产生10ms周期整数倍的信号，对于3.75k的每个RU为32ms的信号，产生RU*5*32ms信号，例如：对于1个RU 1次重复的32ms信号，复制5次产生160ms的数据源信号，对于10个RU，128次重复的40960ms信号，复制5次产生204800ms的数据源信号。
对于NB-PRACH信道，根据重复次数构造完成数据源后，通过后面补0的方法补齐到10ms的整数倍。
将数据源信号前面加入10ms的检测头，这10ms的检测头含有特殊扰码的ZC序列信号。
网络侧不断检测10ms内是否含有特殊扰码的ZC序列信号来找到信号源发送数据的起始位置，进而和信号源发送的起始位置对齐。
本实施例还包括两个具体实例：
实例1
数据源信号可以是NB-PUSCH和NB-PRACH信号。这里以NB-PUSCH的3.75k子载波信号为例。NB-PUSCH的3.75k子载波，单RU，单次重复的无线指标自动化测试方法。
数据源产生：
第一步，生成10ms的检测头信号，其中按照NB_IOT协议生成标准的5.6ms的NB-PRACH信号放在最前面，这5.6ms的NB-PRACH信号同步码字索引值固定设置为1，接下来的4.4ms数据位填0；
第二步，产生待测的数据源信号。NB-PUSCH的3.75k子载波的单个RU，单次重复的周期是32ms，需要将这32ms数据重复5次，凑成160ms。
第三步，将10ms的检测头信号放在前面，后面接着160ms的数据源信号，这样源数据就是170ms的数据，图6是本发明实施例NB_IOT制式上行NB-PUSCH信道单RU单次重复下用于自动化无线指标测试数据源的格式图，数据长度的公式是170ms，见附图6所示。将这170ms的数据放到SMU200A信号源里面，利用SMU200A(信号发射器)信号源周期性发送。
自动检测10ms头：
图7是本发明实施例在NB_IOT制式下对上行NB-PUSCH信号进行的自动搜索10ms检测头和自动化无线指标测试的流程图，见附图7所示，首先，基站侧打开自动检测开关进入自动检测流程，在10ms的起始位置进行NB-PRACH信号的检测，检测的算法与NB_IOT制式下的NB-PRACH的检测算法相同，包括码字生成，固定1/2子载波频偏补偿，时域相关和检测判决几个步骤，当检测到固定码字为1的NB-PRACH信号之后，清除自动检测标志并输出检测到的无线帧号SFN，基站侧进入无线指标测试状态；如果没有检测到固定码字为1的NB-PRACH信号，则对下一个10ms数据进行检测。
无线指标测试：
基站进入无线指标测试状态后，根据NB-PUSCH源数据的RU个数和重复次数来制作上行NB-PUSCH的调度起始位置和周期，起始位置帧号是SFN+1，周期是170ms。
实例2
NB-PRACH的无线指标测试方法。下面举例数据源是NB-PRACH，短循环前缀(Cyclic Prefix，简称为CP)，2次重复的无线指标自动化测试方法。
数据源产生：
第一步，生成10ms的检测头信号，其中按照NB_IOT协议生成标准的5.6ms的NB-PRACH信号放在最前面，这5.6ms的NB-PRACH信号同步码字索引值固定设置为1，接下来的4.4ms数据位填0；
第二步，产生待测的数据源信号，由于检测头的NB-PRACH信号的同步码字索引值是1，那么待测的NB-PRACH的同步码字索引值需要配置成非1。NB-PRACH的数据源短CP，2次重复的周期是11.2ms，需要将这11.2ms数据后面填充8.8ms的0，凑成20ms。
第三步，将10ms的检测头信号放在前面，后面接着20ms的数据源信号，这样源数据就是30ms的数据，图8是本发明实施例NB_IOT制式上行NB-PRACH信道2次重复下用于自动化无线指标测试数据源的格式图，数据长度的公式是30ms，见附图8所示。将这30ms的数据放到SMU200A信号源里面，利用SMU200A信号源周期性发送。
自动检测10ms头：
图9是本发明实施例在NB_IOT制式下对上行NB-PRACH信号进行的自动搜索10ms检测头和自动化无线指标测试的流程图，见附图9所示，首先，基站侧打开自动检测开关进入自动检测流程，在10ms的起始位置进行NB-PRACH信号的检测，检测的算法与NB_IOT制式下的NB-PRACH的检测算法相同，包括码字生成，固定1/2子载波频偏补偿，时域相关和检测判决几个步骤，当检测到固定码字为1的NB-PRACH信号之后，清除自动检测标志并输出检测到的无线帧号系统帧号(System Frame Number，简称为SFN)，基站侧进入无线指标测试状态；如果没有检测到固定码字为1的NB-PRACH信号，则对下一个10ms数据进行检测。
无线指标测试：
基站进入无线指标测试状态后，根据NB-PRACH源数据的重复次数来制作NB-PRACH的调度起始位置和周期，起始位置帧号是SFN+1，周期是30ms。
