Quantization error and distribution.

采样定理的验证，即采样信号的频率大于等于原信号频率的两倍时才能准确的恢复原信号(Verification sampling theorem, the sampling frequency of the signal frequency is greater than or equal to twice the original signal in order to accurately restore the original signal)

matlab的小波分解，重构，去噪以及能量分析(matlab wavelet decomposition and reconstruction, noise reduction and energy analysis)

语音信号的基音检测与估计对信号的估计具有重要作用。用不同方法进行基音检测(Pitch detection signal and the estimated speech signal estimate plays an important role. Pitch detection using different methods)

说明：  对MIMO-OFDM系统通过不同的算法进行仿真得到结果图(Simulation results of mimo-ofdm system are obtained through different algorithms)

在matlab平台下的viterbi编码译码的程序。secrettext.txt是需要传输的文件，encodetext.txt是编码后的文件，decodetext.txt是译码后的文件。(In the matlab platform of the viterbi decoding encoding process. secrettext.txt need to transfer files, encodetext.txt is encoded file, decodetext.txt is after decoding files.)

说明：  语音识别特征提取程序，对语音分析很有帮助(Speech recognition feature extraction procedures, helpful speech analysis)

levy法编制辨识程序，基本精确辨识了系统各个参数，因为误差准则的原因，系数略有差别。(Levy method prepare identification procedure, basic accurate identification of each parameter of the system, because the cause of the error criterion, a slightly different coefficient.)
