摘要:
本文在分析判决反馈RBF网络信道均衡器(DFIBFNE)的结构特点基础上,定义一个布尔向量L作为网络的结构参数,与原来DFRBFNE的隐节点参数集一起构成了新的DFRBFNE隐节点参数集{c,d,L},并给出了一个新的DFRBFNE网络输入输出关系表达式;采用一种混合协同微粒群算法同时对DFRBFNE网络拓扑结构和隐层节点参数进行优化设计,并将 输出线性参数集分离后采用最小二乘法进行优化设计,简化了优化空间,加速了算法的收敛速度。
关键词: 信道均衡器 RBF网络结构 微粒群算法 混合协同
Abstract:
According to the characteristics of the RBFN equalizers with decision feedback, a boolean variable L is defined as the network structural parameter an d is combined with the original reasoning parameter set to form a new parameter set {c, a, L}, and a new expression related input and output of ANFIS isobtained. Then a hybrid cooperative particle swarm optimization algorithm is proposed to optimize the parameter set {c, a, L}, and the output linear pa rameter set {w} is separated to optimize using LMS. In the proposed method, the dimension of the operating space is reduced and the algorithm convergenc e speed is increased by the hybrid PSO.
