预报误差法参数辨识-松弛的思想，有借鉴意义哦，考虑雨衰 阴影 和多径影响。- Prediction Error Method for Parameter Identification- the idea of relaxation, There are reference Oh, Consider shadow rain attenuation and multipath effect.

真的是一个好程序，多抽样率信号处理，部分实现了追踪测速迭代松弛算法。- Really is a good program, Multirate signal processing, Partially achieved tracking speed iterative relaxation algorithm.
