Abstract :
Quadrature amplitude modulation (QAM) is a bandwidth-efficient transmission technique. The exact average bit error ratio (BER) of the maximum-minimum-distance rectangular QAM (R-QAM) constellation is studied in the context of asynchronous cochannel interference (CCI) and Nakagami-m fading. A new formula is derived for the characteristic function (CF) of the CCI, which requires no knowledge of the CCI distribution. The numerical results obtained from our exact BER expression are verified by our simulation results and are also compared to those of the Gaussian approximation (GA).
