Advanced and Easy Expression of Bit Error Rate Calculation for Multiple DF Relay using Rayleigh Fading Channel

Poonam Sonkar

Abstract: In recent times, cooperative communication has been considered as the most developing stage in wireless communication because of its enabling technology for efficient spectrum use and its low power consumption. In this paper, we derive a novel and simple expression of cooperative communication which can overcome the unwanted effects of wireless channel on the message received at the destination which is nearly the same as the theoretical value. In cooperative communication, the three nodes (source, relay, and destination) system, where information transfers between the source and the destination through the selected relay is available in node. The node which is selected should maximize cooperation benefits for the whole system. By applying the technique which is discussed in the paper, we can reduce the error or save the transmit power by which, in turn, we can improve the performance of the network. This paper focuses on the performance of BER using DF relay over the Rayleigh fading channel by using the number of signals received at destination with assistance from the MATLAB tool.
