用于信号特征提取、信号消噪，利用贝叶斯原理估计混合logit模型的参数，LDPC码的完整的编译码，研究生时的现代信号处理的作业，本程序的性能已经达到较高水平，主同步信号PSS在时域上的相关仿真，数学方法是部分子空间法。- For feature extraction, signal de-noising, Bayesian parameter estimation principle mixed logit model, Complete codec LDPC code, Modern signal processing jobs when the graduate, The performance of the program has reached a high level, PSS primary synchronization signal in the time domain simulation related, Mathematics is part of the subspace.
