Abstract :
In this contribution the performance of adaptive modulation-applied in conjunction with a decision feedback equalizer (DFE)-is characterized in a co-channel interference impaired environment over a slowly varying wideband multi-path Rayleigh fading channel. Specifically, joint detection (JD) techniques in conjunction with convolutional coding are invoked, in order to mitigate the effects of co-channel interference in a time division multiple access (TDMA) environment. Finally, the throughput of the adaptive system is compared to that of a range of fixed modulation systems in an interference-limited environment
