The bit error rate (BER) and the average throughput for adaptive quadrature amplitude modulation (AQAM) with constant transmit power over frequency selective Rayleigh fading channels was derived. The effect of multipath diversity on BPS and BER was investigated using I-BER and A-BER constraints. It was found that the effect of multipath diversity can be positive or negative for discrete rate AQAM (D-AQAM), while always positive for continuous rate AQAM (C-AQAM).
