Performance Upper Bound of Adaptive QAM in Slow Rayleigh-Fading Environments
The performance of adaptive modulation schemes that employ either no transmission, BPSK, QPSK, 16 Square QAM and 64 Square QAM is characterised for transmissions over Rayleigh channels. The optimum value for the switching levels between the Axed modulation schemes is found. This is achieved by ,optimising the BER and throughput for wireless computer data and speech systems. Using the optimised switching thresholds, the system performance is also evaluated over Rician channels.

Abstract

The performance of adaptive modulation schemes that employ either no transmission, BPSK, QPSK, 16 Square QAM and 64 Square QAM is characterised for transmissions over Rayleigh channels. The optimum value for the switching levels between the Axed modulation schemes is found. This is achieved by ,optimising the BER and throughput for wireless computer data and speech systems. Using the optimised switching thresholds, the system performance is also evaluated over Rician channels.
