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。In order to improve the channel balance of packet switching network and quality of communication,and reducethe bit error rate of network transmission,a packet switching network transmission channel classification selection algorithmbased 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 timedomain filter method isused to carry out interference suppression in channel,and then the decision feedback adaptive filtering method is combined torealize the network transmission channel classification selection and balance processing.The experimental analysis results showwhen 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.
