基于反向学习的PSO，在图像阈值分割中的应用(Reverse learning PSO-based application in image segmentation threshold)

说明：  全相位FFT算法是天津大学的王兆华和候正信教授提出的，具有初始相位不变和有效防止频谱泄露的特性，在他的相关书籍上做过严格的证明，并有相应的matlab程序。(All-phase FFT algorithm is proposed by Professor Wang Zhaohua and Professor Hou Zhengxin of Tianjin University. It has the characteristics of invariant initial phase and effective prevention of spectrum leakage. It has been strictly proved in his relevant books and has corresponding matlab program.)

This script shows the difference of using zero padding (GI) in the end of OFDM symbol and using cyclic prefix (CP).

The ALOHA protocol was one of the oldest random access protocols, invented by Norm Abramson in 1969. The first wireless network, implementing packet switching over radio, used the pure ALOHA variation, have initially established in Hawaii.
