Abstract :
The effect of the shaping filter excess bandwidth in the performance of symbol-sampled receivers over unknown continuous-time channels is investigated. 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-ray and 3-ray continuous-time channel models.
