基于盲源分离的云无线接入网接入策略
An Access Strategy for Cloud Radio Access Network with BlindSource Separation
摘要
Abstract
Due to the rapid growing popularity of mobile communication technology and abundance of Internet resources,it is quite easy for people to get more convenience and variety of information services.However,the increasing amount of data makes the existing wireless cellular communication system to support heavier burden on the business and provide a higher rate of communication.Therefore,how to improve efficiency of the cellular system is still an important issue.Cloud radio access network technology is a new efficient technology for centralized access network.Based on the cloud cellular,a new method of channel selection has been designed by using the blind source separation algorithm,to make the cellular system select the appropriate channel to improve the efficiency of cooperative communication.Against the poor performance of the system topology,the original access strategy has been improved so that the system has a best error rate performance.The simulation results show that the proposed access strategy has effectively reduced the bit error rate of the system and increasing efficiency of channel.关键词
