周期信号频谱分析，数字滤波器设计，语音信号的处理-Spectral analysis of periodic signals, the digital filter design, and the processing of the speech signal

频谱分析中的倒频谱分析,在各类故障诊断非常有效，本例子是专门针对声音文档，也可用于其他信号-Spectral analysis, cepstral analysis, is very effective in the diagnosis of various types of failures, the present example is dedicated for audio documents, can also be used for other signals

本文在介绍MIMO无线通信系统模型的基础上，通过对比分析几种常用空时编码方法，选定空时分组码对信号进行编码并建立瑞利衰落信道模型，通过对两发一收及两发两收系统的仿真，研究接收天线数对系统接收信号可靠性的影响。之后进一步扩展到不同发射矩阵条件下研究多发一收系统的频谱利用率及误符号率，分析不同天线数目，不同发射矩阵条件下空时正交分组码检测算法的性能。-This paper introduced the MIMO wireless communication system model, through
