摘要: 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 studied in context asynchronous cochannel interference (CCI) and Nakagami-m fading. A new formula derived for characteristic function (CF) CCI, which requires no knowledge CCI distribution. numerical results obtained from our BER expression are verified by simulation also compared to those Gaussian approximation (GA).
