一个波束形成的例子，比较了在瑞利信道中使用波束成形和不使用波束成形的误码率。(An example of beamforming is made to compare beamforming and without beamforming bit error rate in Rayleigh channel.)

MATLAB MIMO-OFDM信道估计仿真.m文件。基于梳状导频环境。(MATLAB MIMO-OFDM channel estimation simulation. M file. Comb based pilot environment.)

NLMS for channel equalization

说明：  FBMC框架的搭建，和OQAM+PPN多项滤波器，大概框架都有(The construction of fbmc framework and OQAM + PPN multiple filters, probably all of them have)

ti的微型逆变器技术方案，很好的参考，帮助学习。(The Micro-inverter Technology Program Of TI)

最近看到的一些关于盲源分离的算法，这是基于最大熵原则的盲源分离算法(Recently seen a number of blind source separation algorithm, which is based on the principle of maximum entropy algorithm for blind source separation)

其中包含了OFDM系统的简单仿真，有SLM算法输入输出的比较，PAPR明显降低(Which contains a simple simulation of the OFDM system, the comparison of the input and output of SLM algorithm, PAPR is significantly reduced)
