Bit Error Probability of BPSK Modulation for AWGN Channel

susan编写的关于fdtd算法的书中的2D部分的程序(susan book written fdtd 2D program)

提取声音信号的MFCC特征参数，然后进行匹配，有训练语音，也有测试语音，测试信号既有训练过的，也有没训练过的，都可以识别(The MFCC feature parameters of sound signal are extracted and matched. There are both trained and tested voices. The tested signals can be recognized by both trained and untrained voices.)

matlab基本程序，动态系统仿真，单位跃阶相应特性(matlab basic procedures, dynamic system simulation, units of the corresponding characteristics of jump-order)

蓝牙信号仿真子系统，通过matlab模块中的simulink进行信号仿真(Bluetooth signal simulation, simulation matlab simulink module extraction parameters)

MUSIC算法，即多重信号分类法，经典的高分辨方位估计估计方法，好好学习一下(Multiple signal classification, which is the tipical DOA method with high resolution, should be well studied.)

针对案例数据，用matlab软件对数据进行极差法归一化处理；并使用主成分分析法分析选定成分的特征值贡献率，从而为进行下一步数据分析做一些准备。(According to the case data, the data is normalized by range method with MATLAB software, and the contribution rate of the selected components is analyzed by principal component analysis, so as to make some preparations for the next step of data analysis.)
