Upper-Bound Performance of a Wide-Band Adaptive Modem

Upper-Bound Performance of a Wide-Band Adaptive Modem
Upper-Bound Performance of a Wide-Band Adaptive Modem
Adaptive modulation is applied in conjunction with a decision-feedback equalizer (DFE) in order to mitigate the effects of the slowly varying wide-band multipath Rayleigh fading channel in a noise-limited environment. An upper-bound mean bit-error rate and bits per symbol performance is introduced for this scheme by utilizing the pseudo signal-to-noise ratio at the output of the DFE in order to switch the modulation schemes on a burst-by-burst basis. Index Terms—AQAM, QAM, quadrature amplitude modulation, wide-band adaptive modulation.

Abstract

Adaptive modulation is applied in conjunction with a decision-feedback equalizer (DFE) in order to mitigate the effects of the slowly varying wide-band multipath Rayleigh fading channel in a noise-limited environment. An upper-bound mean bit-error rate and bits per symbol performance is introduced for this scheme by utilizing the pseudo signal-to-noise ratio at the output of the DFE in order to switch the modulation schemes on a burst-by-burst basis. Index Terms—AQAM, QAM, quadrature amplitude modulation, wide-band adaptive modulation.
