Capacity Analysis of Adaptive Cooperative Communication Systems Using Selection Combining
Guangqiu Li · Journal of Hangzhou Dianzi University · 2010
This paper derived exact closed-form expressions for the average channel capacity of a decode-and-forward(DF) cooperative communication system using selection combining(SC) on Rayleigh fading channels under three adaptive transmission policies: variable rate and variable power(VRVP),variable rate with constant power(VR),and truncated channel inversion with fixed rate(TIFR).Numerical and simulation results show that the average channel capacity of adaptive cooperative communication system can be improved with the increase of the number of receive antenna of the relay,and the destination.
