一些常用的通信系统仿真，16qam、64qam误码分析，turbo。(Some commonly used communication system simulation, 16qam, 64qam error analysis, turbo.)

说明：  KPCA的提出者亲自写的程序。是一份很值得收藏的经典代码。(KPCA the author himself procedures. It is a very worthwhile collection of classic code.)

该例程内容丰富，包括从基本的bpsk,qpsk,qam到实际的ofdm系统，cdma链路，mac层仿真分析，对OFDM信道建模，包括普通IDFT算法和IFFT快速算法，基于OFDM体制的调制和解调程序，降低OFDM系统PAPR的pts算法的仿真程序，完整的OFDM链路程序并作了较为具体的解析(The routines cover a wide range from basic bpsk, qpsk, qam to the actual ofdm systems, cdma link, mac layer simulation, the OFDM channel modeling, including ordinary IDFT algorithm and IFFT fast algorithm, based on OFDM modulation system and demodulation process, reduce the PAPR of OFDM system pts algorithm simulation program, a complete OFDM link process and made more specific analysis)

以往的测时间延迟的方法时利用信号相关性来求的，利用MUSIC算求两信号的时间延迟具有很高的精度。(Measurement of time delay before the method used to seek correlation signal, the use of MUSIC operators seek time delays of two signals with high precision.)

用matlab实现支持向量机功能，可以进行四种核函数的选择，简单实用(support vector machine)

说明：  快速傅里叶变换，可对相关数据进行频域分析(fast fourier transfer)
