Performance Analysis and Comparison of AF and DF Relaying Systems in Rayleigh Fading Channel considering Poisson Interference Field: Performance Comparison of AF and DF Relays in Rayleigh Fading under Poisson Interference Field

摘要

During this paper, analyzed the performance of transmission systems that comprises amplify-and-forward (AF) and decode-and-forward (DF) relays over a Rayleigh attenuation surroundings within the presence of a Poisson field of interferers. The interference model considers the impact of abstraction distribution of co-channel interferers within the neighborhood of the relays and therefore the destination node. Considering the end-to-end signal-to-interference quantitative relation, the outage probability of system springs. the precise average bit error rate (BER) of binary modulations and therefore the average data rate area unit evaluated numerically. Finally, straight line expressions for the system outage probability and therefore the end-to-end BER area unit derived which offer some inferences concerning the factors moving the performance of the thought-about system. The novel expressions may be wont to show the impact of interference model parameters like the transmit power, path loss exponent, and abstraction density of interferers on the performance of multi-hop wireless systems. Simulation results area unit more provided to demonstrate the accuracy of the analytical expressions.
