Abstract

A novel adaptive modem scheme is presented for transmissions over wideband mobile channels, which employs a radial basis function (RBF) based decision feedback equaliser, in order to mitigate the effects of the dispersive wideband channel. Turbo codes are invoked for improving the bit error rate (BER) and bits per symbol (BPS) performance of the scheme, which is shown to give a significant improvement in terms of mean BPS performance compared to that of the uncoded RBF equaliser assisted adaptive modem
