Abstract
It is known that, when using a multi-tone FSK scheme in a wideband fading channel to achieve the wideband capacity limit, the codeword probability of error decays very slowly with bandwidth. In this paper, we consider a modified multi-tone FSK scheme which employs a feedback link. We show that, a small amount of feedback improves the error performance significantly
