this folder contains matlab codes for minimize sphere with pso algorithm.

Block-interleaver/deinterleaver according to the IEEE 802.11-2007 Defined by two step-permutation : The first permutation ensures that adjacent coded bits are mapped onto nonadjacent sub-carriers. The second ensures that adjacent coded bits are mapped alternately onto less and more significant bits of the constellation and, thereby, long runs of low reliability (LSB) bits are avoided. Tested and works well

小波变换程序,主要是提升小波的变换。包含两个程序，一个是子程序。(wavelet transform)

瑞利信道的仿真程序，很经典！！建议查看(Rayleigh channel simulation program, classic! ! Recommendations View! !)

说明：  ofdm 仿真程序，对大家的毕业设计会有帮助的。

Speeding Up Optimization Problems with Parallel Computing - Webinar - 10 August 2010

bat algorithm for optimization

卷积码的仿真，其误码率实验值与理论值比较，调用函数，可以方便在以后的算法应用。(Simulation of a convolutional code, bit error rate value is compared with the theoretical value experiment, the calling function, the algorithm can be easily applied in the future.)

matlab 学习技巧，现在把我用的，也就是对我帮助很大的留个文件传上去，希望对大家有用，第三程序设计(matlab learning skills, and now I use, which is a great help to me to leave a document passed up, we want to be useful, the third program design)

该程序实现心电信号的去噪，同时对原信号与去噪后的信号进行对比(De-noising of ECG signal)
