Abstract :
The performance of selection diversity reception in a correlated Rayleigh fading environment is studied. A simple probability density function (PDF) is derived for the output signal-to-noise ratio of a selection diversity receiver. Using the PDF, the bit error rates for DPSK and NCFSK are calculated to show the effect of correlation (or distance) between the diversity antennas. The numerical results show that the distance between diversity antennas can be as small as 0.3 λ
