无线通信考试 介绍 该项目的目的是使用Simulink和Matlab评估和校正QPSK调制中的IQ失衡。 振幅和相位不平衡都会发生,如下图所示。 用于查看已保存信号的Simulink模型来自的示例如下图所示。 这些文件以前保存为801帧,包含12500个样本。 编码 Simulink模型允许查看不平衡的已保存信号 signal_1:不平衡信号 signal_2:功率高于signal_1的不平衡信号 signal_IQ10:传输中不平衡度为10%的信号 signal_IQ20:传输中有20%不平衡的信号 signal_IQ30:传输中有30%不平衡的信号。 函数从信号中删除前零 函数将IQ不平衡应用于信号 函数根据信号估计不平衡 函数校正信号的不平衡 功能使用comm.IQImbalanceCompensator的信号估计的幅度和相位失衡 有关更多信息,请在Matlab中输入: hel
