Abstract

This paper introduces multihop relay system where the benefits of spatial diversity are achieved from the concurrent reception of signals that have been transmitted by multiple terminals. Amplify and forward cooperative relays will be used in this system. It will be obvious that multihop system can effectively mitigate the performance deterioration caused by fading, without imposing delay or bandwidth expansion. The channel models are compared through the simulations to prove that multihop system is better than single hop system where it gives low symbol error rate and therefore the performance will be improved. Maximum Ratio Combining will be used. Analysis of different hops system will be made. Different modulations will be applied. From simulation results it will be obvious that symbol error rate will be reduced when using multihop than single hop.
