| 摘 要： | 为了充分利用"0","1"码元经过冲击滤波器后的波形差异和有效改善基本支持向量机经典训练方法容易陷入局部最优的缺陷,设计了混合蛙跳算法优化的支持向量机EBPSK检测器.首先,从经过冲击滤波器的"0","1"码元原始数据中提取训练集和测试集,并进行归一化处理;然后,利用混合蛙跳算法的全局寻优能力在训练集空间搜索支持向量机...

| Abstract: | To take full advantage of the waveform difference of 0 and 1 symbols when passing the impacting filter and improve the defect of easily falling into local optimum when using basic support vector machine(SVM),the SVM detector based on the shuffled frog leaping algorithm(SFLA) is designed in the extended binary phase shift keying(EBPSK) communication system.First,the training set and the testing set are extracted from the original 0,1symbols which pass the impacting filter,and are normalized.Then,the SFLA is ... |
