In recent years, there have been many researches about cooperative communication. In this research, we will concentrate on transmission with multihop it is a part of cooperative communication. Multihop transmission is process transmitted from source to destination by one or more relay nodes. In order to evaluate the process of the impact of these factors on the transmission process, theories of noise distribution, fading, Outage probability are given for evaluation. The results of the simulation to assess the Outage probability indicate that the reuse of spatial frequency, the Outage probability decreases as SNR increases with the condition of limited noise. The Outage probability decreases with the space reuse factor Q (co-channel interference is higher when Q is small). At the same time, the BER ratio was also included for evaluation with the MRC method on the receiving side. The results show that the two relays model gives the best BER ratio.
