xwch_test.m是主测试文件;biaoji.mat存放滤波器系数;xiangweicha.m用FFT计算相位差。
仿真框架为:
1.标记信号和双音信号续接作为发送信号;
2.对双音中一个频率分量的相位做偏移,再经过一个低通滤波器(引入线性相位,模拟收发不能同步测量现象)后,作为收到的信号;
3.用一个检测信号对收发信号进行相关运算;
4.画出收发信号以及相关处理后的信号。找出相关信号的那个尖点,从而推算出收发双音信号0相位点;
5. 输入0相位点位置,计算相对相位差。(xwch_test.m is the main test file biaoji.mat store filter coefficients xiangweicha.m calculated using FFT phase difference. Simulation framework: 1. Mark signals and then as a two-tone signal continued to send signals 2. On a two-tone frequency components of the phase shift to do, and then through a low pass filter (the introduction of linear phase, simulation can not simultaneously send and receive measuring the phenomenon), the as received signal 3. using a detection signal of the transceiver signal correlation operation 4. draw send and receive signals and related processed signal. Correlated signal of the cusp, which calculate the two-tone signal transceiver 0 phase point 5. Enter 0 phase point position, calculate the relative phase difference.)
