Power-spectrum-estimation

本代码是王岩数理统计与MATLAB工程数据分析一书的所有源代码。特点着重基础、强化应用、便自学，是工程数据分析一本很好的书，代码说明也较为详细，本人极力推荐！(This code is WangYan mathematical statistics and data analysis of the MATLAB project book all the source code. Based on characteristics, strengthening the application, and self-study, engineering data analysis is a very good book, code and a more detailed instructions, I highly recommend!)

OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀（CP）可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是，过长CP会使得数据传输效率降低。可以采用最小均方误差（MMSE）信道缩短均衡技术来压缩信道冲击响应长度。(OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than the channel impulse response length before the time-domain symbol. However, long CP will reduce the efficiency of data transmission. A minimum mean square error (MMSE) channel shortening equalization technique may be employed to compress the channel impulse response length.)
