LFM信号及回波的生成，时域及频谱分析，模糊度函数分析，时频分析，匹配滤波器能量检测、循环相关检测、及fmusic参数估计(LFM signal and the echo generation, time domain and spectral analysis, ambiguity function analysis, time-frequency analysis, the matched filter energy detection, loop correlation detection, parameter estimation and fmusic)

基于OFDM的多准则下认知无线电资源分配问题的研究,认知无线电资源分配(Cognitive radio resource allocation problem of OFDM multi-criteria research, cognitive radio resource allocation)

zore-forcing SIC simulation

详细介绍了ldpc编码以及如何在matlab的simulink 上实现(ldpc matlab simulink)

说明：  载波同步仿真，使用的是反馈补偿法，接收信号经补偿矩阵，误差提取，环路滤波，相位累加器后反馈回补偿矩阵，稳定后估计相位趋近相位差，存在相位模糊情况。(the simulation of the carrier synchronization)
