BER Analysis and Evaluated for Different Channel Models in Wireless Cooperation Networks Based OFDM System

The Cooperative wireless network is a mean to improve the ideas of using the broadcast nature of channel wireless to make the nodes communicate and help one another. In this paper the analysis of BER of wireless cooperation networks have been used different types of fading channels to estimate the error rate performance for wireless transmission and it is suited to network with OFDM system. So we will compare three models Rayleigh, Rician and Nakagamim fading channels then we will study the effect of each of them in terms of efficiency link Fading channels Environments. BPSK has been employed as the modulation technique and AWGN has been used as the channel no noise. The SNR was used to estimate the channel performance, then we discuss it with different three channels (Rayleigh, Rician and Nakagami) and we compared and simulated their BERs accordingly. Our Mat lab Simulation Results showed were compared three channels by their BER, namely, Rayleigh, Rician and Nakagamim. Through the results and found that the value of BER in Nakagami-Cm Best case.
