使用多路径信道进行数据的传输仿真（架设在已知信道中传输）(Data transmission using the multi-path channel simulation (mounted on a known channel transmission))

说明：  小波分析的matlab程序，用于聚类分析，是一种不错的算法(The matlab program of wavelet analysis, used for clustering analysis, is a good algorithm)

《gps基本原理及其matlab仿真》(西安电子科技大学)里面的程序源代码，都是自己亲自敲上的。对入门很有用的。这是获取C/A码信息的。(The basic principle of GPS and the matlab simulation (xi an university of electronic science and technology) in the program source code, is knock on yourself. The introduction is very useful. This is the C/A code information. )

tvfemd可进行序列分解，比emd分解效果可能要好一点。(he sifting process is completed using a time varying filter technique.The local cut-off frequency is adaptively designed by fully facilitating the instantaneous amplitude and frequency information. Then nonuniform B-spline approximation is adopted as a time varying filter. In order to solve the intermittence problem, a cut-off frequency realignment algorithm is also introduced. Aimed at improving the performance under low sampling rates, a bandwidth criterion for intrinsic mode function (IMF) is proposed. TVF-EMD is fully adaptive and suitable for the analysis of linear and non-stationary signals. Compared with EMD, the proposed method is able to improve the frequency separation performance, as well as the stability under low sampling rates. Besides, the proposed method is robust against noise interference.)
