Abstract

An analytic study applying an M-ary PSK adaptive modulation scheme in a Rayleigh-lognormal fading channel is proposed. The closed-form expressions of the average BER and the average data throughput (BPS) of the proposed adaptive modulation system with constant transmitted power over the fading channel are presented. The effect of shadowing on BER and throughput in the adaptive modulation system is also investigated. The results show analytical expressions for the average BER and data throughput derived for transmission over a Rayleigh-lognormal fading channel. Our analyzed results show good agreement with Monte Carlo simulation ones. The proposed method is useful in enhancing the data throughput of a communication system, such as a third generation wireless communication system, where a huge amount of bandwidth is needed for high-speed multimedia services.
