Abstract
This paper describes the effect of postdetection selection combining diversity on voice signal transmission for wide-band PM and narrow-band PM in a Rayleigh fading environment. First, the baseband average SNR versus the average CNR for a twobranch selection diversity with the syllabic Compandor is derived in a closed form including the effect of the envelope Correlation coefficient. Then, the dual selection diversity receiver, which shares an envelope detector with two branches in time division, and its performance are described. Finally, laboratory tests using a Rayleigh fading simulator are carried out with the result that an effective diversity improvement is obtained for a cross correlation coefficient in the range from 0 to 0.5.
