This procedure is based on the use of denoising techniques, as opposed to the conventional front-ends which use linear time-invariant filters. An analytical performance evaluation of this procedure in AWGN channels is addressed here. In addition, a new performance comparison with conventional techniques for frequency selective channels is also presented, which is based on computer simulations.</span> ER -
