Abstract :
The performance of selection diversity over independent but not necessarily identically distributed Nakagami fading channels is studied. An exact closed-form expression for the probability density function of the selected channel signal-to-noise ratio is derived. Exact closed-form expressions for the corresponding cumulative distribution function, moment generating function and moments are also obtained. The results are used to obtain outage probabilities and achievable bit rates for an adaptive modulation and coding scheme with multicode transmission as employed in systems similar to the high speed downlink packet access channel or the 3GPP cellular standard
