this source code is useful to do cdma simulation in awgn channel..

混沌序列中的自相关检验混沌序列中的自相关检验混沌序列中的自相关检验(chaos logsitic themself)

说明：  对一个简单地系统，设计pid控制器使其控制它的稳定(For a simple system, a PID controller is designed to control its stability.)

mfile for matlab program

bpsk 调制解调　该仿真程序是BPSK在AWGN信道下的调制解调性能验证实例(bpsk modulation and demodulation of the simulation program is BPSK AWGN channel in the modulation and demodulation performance verification Examples)

Simpson integration method(3/8)

(3,1,3)SOFT_HARD CODEING

matlab图像水印嵌入处理，运用DCT算法进行嵌入和提取。(Matlab watermark embedding process, using DCT algorithm to embed and extract. )

说明：  此程序为DS-CDMA链路中加入基于子空间的PAST多用户检测方法。系统中采用m序列阔频，可以通过高斯信道或瑞利信道。可以直接运行得到不同信噪比下的误码率曲线。(This procedure for the DS-CDMA link by adding the PAST subspace-based multi-user detection methods. System m sequence used in wide-band, you can channel through the Gaussian or Rayleigh channel. Can be directly run different SNR BER curves.)
