Upper-Bound Performance of a Wideband Burst-by-Burst Adaptive Modem
Upper-Bound Performance of a Wideband Burst-by-Burst Adaptive Modem
In this contribution, adaptive modulation is applied in conjunction with a Decision Feedback Equalizer (DFE) in order to mitigate the effects of the slowly varying wideband multi-path Rayleigh fading channel. The upper-bound mean BER and Bits Per Symbol (BPS) performance of this scheme is determined by utilizing the pseudo-SNR at the output of the DFE, in order to switch the modulation schemes on a burst-by-burst basis. The performances of each individual modulation schemes and their amalgamated adaptive scheme were compared in terms of information throughput for a low- and a high- BER arrangement. The results indicate both SNR gains of approximately 1 - 3dB and 7 - 9dB, for the high- and low- BER arrangement, respectively using the proposed burst-by-burst adaptive wideband scheme in a noise limited environment.

Abstract
In this contribution, adaptive modulation is applied in conjunction with a Decision Feedback Equalizer (DFE) in order to mitigate the effects of the slowly varying wideband multi-path Rayleigh fading channel. The upper-bound mean BER and Bits Per Symbol (BPS) performance of this scheme is determined by utilizing the pseudo-SNR at the output of the DFE, in order to switch the modulation schemes on a burst-by-burst basis. The performances of each individual modulation schemes and their amalgamated adaptive scheme were compared in terms of information throughput for a low- and a high- BER arrangement. The results indicate both SNR gains of approximately 1 - 3dB and 7 - 9dB, for the high- and low- BER arrangement, respectively using the proposed burst-by-burst adaptive wideband scheme in a noise limited environment.
