OFDM信道的参数估计模拟。QDPSK调制，采用训练信号。(OFDM channel estimation simulation.)

说明：  实现LDPC信道码的仿真，已在大型软件开发项目中实用(LDPC code and decode matlab)

一个CMA算法程序，可以对CMA算法进行一些仿真研究(A CMA algorithm procedures, CMA algorithm can carry out some simulation studies)

说明：  TDMA的opnet仿真模型，比较简单，适合初学者(TDMA the OPNET simulation model is relatively simple, suitable for beginners)

通过伪随机序列进行频率调制，并对相位连续性进行优化。调制信号的自相关函数可以通过谱修正进行旁瓣抑制(Frequency modulation is performed by pseudo-random sequence and phase continuity is optimized. The autocorrelation function of modulation signals can be sidelobe suppressed by spectral correction)

matlab中使用FFT算法求两个信号的时频二维（互模糊）函数，可以实现信号的时延、多普勒频移联合估计（需要根据实际场景适当修改参数）(oint estimation matlab frequency two-dimensional FFT algorithm seeking the two signals (cross ambiguity) function, signal delay, Doppler shift)

实现局域网内的通讯。类似于QQ聊天室可以群聊(Communication within a LAN.)

这是在uwb系统中,用TOA定位法的整个系统的仿真程序(This is the uwb system, using TOA positioning of the whole system simulation program)

lms基础算法，已经经过测试，可以通过。(LMS basic algorithm has been tested and passed.)

说明：  不同信噪比下，能量检测虚警概率与检测成功率的关系(The relationship between energy detection false alarm probability and detection success rate under different SNR. .)
