- Abstract
Abstract  The effect of the shaping filter excess bandwidth in the performance of symbol-sampled receivers over unknown continuous-time channels is investigated. The shaping filter overall response is divided between the transmit and receive filters. The performance loss is determined in terms of information rate, and relative to the case of perfectly synchronized matched filtering, where the continuous-time channel has to be known a priori. Numerical results are presented for the case of a raised cosine shaping filter and 2- and 3-rays continuous-time channel models. We show that the losses increase with the increase of the excess bandwidth, reaching a maximum at 100% excess bandwidth, and a minimum at no excess bandwidth.
