说明：  ANN-BP分类器设计，用其中一半的数据采用ANN-BP算法设计分类器，另一半数据用于测试分类器性能。(ANN-BP classifier design, with half of the data using ANN-BP algorithm design classifier, the other half of the data used to test the classifier performance.)

Carrier frequency offset estimation

To find and estimate of the best solution and parameter in our problem we can use the evolutionary programming. PSO (particle swarm optimization) is an applicable method to catch this target. In these files I show the Simple PSO that it can be base of solve complicated problem, the code could run by MATLAB.
