Abstract
The combined effect of postdetection diversity reception and concatenated channel coding on the BER floor of π/4-shift QDPSK due to multipath channel delay spread in Rayleigh fading environments is experimentally investigated. Two- branch postdetection MRC diversity and Reed-Solomon/ BCH concatenated coding are applied. Experimental results show that for a BER floor of 10−5 the tolerable RMS delay spread can be increased by ~70% over the uncoded, diversity reception case.
