摘 要: 为了提高分组交换网络的信道均衡性,改善通信质量,降低网络传输的误码率,提出一种基于判决反馈自适应筛选的分组交换网络传输信道分类选择算法。采用自适应加权控制对分组交换网络的信道相位信息进行星座图划分,采用横向时域滤波器方法进行信道中的干扰抑制,然后结合判决反馈自适应筛选方法实现网络传输信道的分类选择及均衡处理。最后进行实验分析,结果表明采用该算法进行分组交换网络传输信道分类选择时,信道的自适应均衡性能较好,网络数据传输的误码率较低。

Abstract: In order to improve the channel balance of packet switching network and quality of communication, and reduce the bit error rate of network transmission, a packet switching network transmission channel classification selection algorithm based on decision feedback adaptive screen is proposed in this paper. The adaptive weighted control is adopted to perform constellation graph partition for channel phase information of packet switching network. The transverse time?domain filter method is used to carry out interference suppression in channel, and then the decision feedback adaptive filtering method is combined to realize the network transmission channel classification selection and balance processing. The experimental analysis results show when the algorithm is used for transmission channel choice of the packet switching network, the adaptive equalization performance of channel is good and the error rate of network data transmission is low.
Keywords: packet switched network; transmission channel; classification selection; adaptive equalization
隨着网络信息技术的发展,采用网络通信进行数据传输成为人们进行数据传输和信息交流的必备手段,构建分组交换网络,实现低频、中频、高频、甚高频和特高频信号与信息的交互,并通过信道均衡和调制解调,以提高数据传输的质量[1]。在分组交换网络中,由于分组交换网络信道的多普勒效应会产生强烈的干扰和数据传输信道的失衡,导致分组交换网络数据传输质量降低,才需要进行卫星传输信道的分类优化选择[2],提高网络通信的质量。本文提出一种基于判决反馈自适应筛选的分组交换网络传输信道分类选择算法,通过信道均衡优化设计,使用信道分类选择优化,改善分组交换网络的组网和通信传输性能。……
