阵列信号处理 各种经典算法 MUSIC ESPRIT等 值得珍藏(Array signal processing algorithms blessed with a variety of classic)

录制自己的一段语音，时间控制在15秒到30秒左右；利用wavread函数对自己的语音进行采样，记住采样频率。 （1）画出原始语音信号的时域波形，而后以1秒为间隔，求出每秒数据的功率谱。 （2）根据语音信号特点，分别设计FIR及IIR滤波器，分别画出滤波器幅频和相频特性曲线。用设计的滤波器对信号滤波，画出滤波后时域波形。用sound函数回放语音信号。 （3）求出特征频段语音信号随时间变化的曲线（每间隔0.05秒求一次功率谱）。 (Record your own voice for some time (15 seconds to 30 seconds) use wavread function of the voice samples, remember the sampling frequency. (1) Draw the original speech signal in time domain waveform, and then to 1 second intervals, the data obtained power spectrum per second. (2) According to the voice signal characteristics, FIR and IIR filters were designed, namely to draw the amplitude and phase frequency characteristic curve. With the design of the filters on the signal filtering, to draw the filtered time-domain waveform. Playback with sound function of the speech signal. (3) Find the characteristic band speech signal curve over time (0.05 seconds intervals seeking a power spectrum.))

可对OFDM信道进行预测，对初学者会有帮助~(OFDM Channel estimators.It will be helpful1)

Code of Fuzzy Logic Method

说明：  OFDM系统中基于LS 和 MMSE 的信道估计(OFDM Systems Based on LS and MMSE channel estimation)

LDA学习用到的算法，不是自己写，别人的，拿来学习用(LDA learning algorithm is used, not her own writing, others, used to learn)

This program is to find the local peaks in the signal.
