Abstract

Abstract: The performance of the adaptive modulation system over Nakagami fading channelsis analyzed, which utilizing four modulation modes. The optimization criterion of the setting of the modulation switching levels is to maintain the target BER,which is desired by many data services. Under this condition, the performance analysis of the throughput and the transmission outage probability of the adaptivemodulation system are presented. We do so by adopting the numerical analysis methods. Finally, the simulation results show that the adaptive modulation systemcan theoretically achieve high throughput performance, and low transmission outage probability under certain conditions.

Key words: adaptive modulation, Nakagami fading, rate bit error
