通信系统中的OQPSK，并且与QPSK相比较。matlab实现(Communication Systems OQPSK, and compared with QPSK. matlab achieve)

pso算法的代码，是一种基于叠代的优化工具。系统初始化为一组随机解，通过叠代搜寻最优值，(PSO algorithm code is based on an iterative optimization tools. Initialize the system for a group of random solutions, through iterative search for the optimal values,)

Fuzzy c-means (FCM) with spatial constraints has been considered as an effective algorithm for image segmentation. Student’s t-distribution has come to be regarded as an alternative to Gaussian distribution, as it is heavily tailed and more robust for outliers. In this letter,
