On the estimation capacity of equal gain diversity scheme under multi-path fading channel

Abstract

This paper investigates analytically-derived close-form expressions for capacity per unit bandwidth in Rayleigh fading channels with equal gain combination (EGC) diversity. We consider power and rate adaptation with constant transmit power, channel inversion bit rate, and truncated channel inversion adaptation policies. To evaluate the performance of the system, we simulate under ideal communication conditions, the different diversity schemes and compare their performance. We discover after extensive simulation that the truncated channel inversion policy outperforms other adaptation policies, while the constant power policy provides the lowest capacity, compared to other policies. © 2013 Springer Science+Business Media.
