本实施例中的全局参数包括采集卡参数和频谱参数，采集卡参数包括增益、采样点数和采集卡带宽，频谱参数包括频谱中心频率、跨度、时隙和时延。
确定频谱参数，例如：频谱中心频率设置为2524.85MHz；跨度设置为1000e6Hz；时隙，0-279，如CSI-RS:12；时延，单位为秒，如0.003秒。具体地，本实施例中的频谱参数是无线信号频谱通用参数。

其中，ceil()表示向上取整函数，span表示跨度，bw表示采集卡带宽。
S103、初始化采集卡的已采集次数。

上述采集卡采集为一次采集。
本实施例中的目标基站指定采样点数的IQ数据集即目标基站数据。
S108、根据目标基站数据，得到中间数组，并对采集卡的已采集次数加一。
