Abstract

This paper deals with the presentation of a joint equalizer/channel decoder for the transmission of a digital modulation, with a convolutional encoder, on a dispersive channel with additive white Gaussian noise. This equalizer directly produces the detection of the emitted sequence of information bits rather than the ones after channel coding, as classically done, i.e., the novelty of this blind equalizer is to include the decoding step directly in the equalizer´s structure.
