Abstract

Abstract:

The performance of amplify-forward (AF) and decode-forward (DF) is analyzed in the two basic single relaying modes for a single-relay system in the Rayleigh fading environment. This paper investigates the impact of the relay's position on the system capacity and probability of error for both AF and DF schemes. The position of the relay is crucial to the performance. The result shows that depending on transmission power, channel noise and path loss the best performance is achieved when the relay is at an equal distance from the sender and the destination in AF or the relay is closer to the source around in DF.

Key words: cooperative communication, relay networks, amplify-forward, decode-forward
