Radial Basis Function Decision Feedback Equaliser Assisted Burst-by-Burst Adaptive Modulation
Radial Basis Function Decision Feedback Equaliser Assisted Burst-by-Burst Adaptive Modulation
The performance of radial basis function decision feedback equalised burst-by-burst adaptive modulation is presented for transmission over dispersive wideband mobile channels. Radial Basis Function (RBF) network based channel equalisers have a close relationship with Bayesian schemes. The RBF decision feedback equaliser (RBF DFE) is capable of estimating the 'short term bit error rate' of the received data burst and this estimate is used as the modem mode switching criterion in order to switch between different modulation schemes. This scheme is shown to give a significant improvement in terms of mean bit error rate (BER) and bits per symbol (BPS) performance compared to that of the individual fixed modulation schemes.

Abstract
The performance of radial basis function decision feedback equalised burst-by-burst adaptive modulation is presented for transmission over dispersive wideband mobile channels. Radial Basis Function (RBF) network based channel equalisers have a close relationship with Bayesian schemes. The RBF decision feedback equaliser (RBF DFE) is capable of estimating the 'short term bit error rate' of the received data burst and this estimate is used as the modem mode switching criterion in order to switch between different modulation schemes. This scheme is shown to give a significant improvement in terms of mean bit error rate (BER) and bits per symbol (BPS) performance compared to that of the individual fixed modulation schemes.
