文化算法的MATLAB实现。实验结果表明该算法具有良好的性能。(MATLAB implementation of cultural algorithms. Experimental results show that the algorithm has good performance.)

this code shows the implementation of a transmission chain. First, the codage with Gray(MDA-4), then the over sampling, the filtrage before emission, the filtrage in reception with the same filter(in order to be adaptative). then the decision within the value of the final signal in the reception.

说明：  利用PTS技术降低峰均比，并作出与未使用降低PAPR技术的CCDF对比图形(Comparing with OFDM system without PAPR reduction techniques,figure the CCDF using PTS technique.)

包含多个完整的ofdm相关仿真程序，满足需要(Ofdm multiple complete the relevant simulation program, to meet the needs)

峰值滤波用于数据特征处理，可提高算法运算速度和鲁棒性(Peak filter characteristics for data processing, the operation speed can be increased and the robustness of the algorithm)
