Performance of selection diversity systems in a Nakagami fading environment

Closed form results for the symbol error probabilities are derived for M-ary, L branch selection diversity system in a Nakagami fading environment using noncoherent frequency-shift keying modulation. The maximum SNR selection and the maximum output selection schemes are considered. The analysis is not limited to integer values of the Nakagami fading parameter m. Results for the Rayleigh fading channel are obtained and presented as special cases of those of the Nakagami fading model. The symbol error probability when the diversity branches undergo different fading statistics with unequal mean SNR are considered for the maximum SNR selection scheme. Outage probabilities are also calculated for the maximum SNR selection scheme.<<ETX>>
