An Improved Method of Wireless Multihop Communication System
Ye Wei · Communications technology · 2010
This paper discusses bi-directional transport stream for improving the spectrum efficiency in the wireless multi-hop relaying system,and this relay technology is just the so-called Bi-directional Amplify Throughput-relaying(BAT-relaying).In BAT-relaying,the predecessors have proposed two ways: decode and forward BAT-relaying(DF BAT-relaying) and amplify and forward BAT-relaying(AF BAT-relaying).In this paper,an improved method based on AF BAT-relaying is proposed,which removes noise and then launches information before forwarding.And simulation analysis that indicates this method could fairly improve the spectrum efficiency.
