In this paper it is proposed a space-time algorithm for co-channel interference (CCI) and intersymbol interference (ISI) reduction for GSM/DCS systems. The temporal channel for the Viterbi receiver and the beam-former weights for CCI rejection are estimated jointly by optimizing a suitable cost function for low-rank space-time channels. Compared to the solutions proposed in the literature, the advantages are: i) the reduction of the CCIs still using, for the equalization, a scalar Viterbi receiver and ii) the convergence of the estimates within few symbols of the training sequence. Performances are evaluated by simulations.

Abstract
In this paper it is proposed a space-time algorithm for co-channel interference (CCI) and intersymbol interference (ISI) reduction for GSM/DCS systems. The temporal channel for the Viterbi receiver and the beam-former weights for CCI rejection are estimated jointly by optimizing a suitable cost function for low-rank space-time channels. Compared to the solutions proposed in the literature, the advantages are: i) the reduction of the CCIs still using, for the equalization, a scalar Viterbi receiver and ii) the convergence of the estimates within few symbols of the training sequence. Performances are evaluated by simulations.File in questo prodotto:
