This paper presents a single chip implementation of a space-time algorithm for co-channel interference (CCI) and intersymbol interference (ISI) reduction in GSM/DCS systems. The temporal channel for the Viterbi receiver and the beamformer weights for the CCI rejection are estimated jointly by optimizing a suitable cost function for separable space-time channels. By taking into account nowadays integration capabilities provided by FPGA (Field Programmable Gate Array), it is demonstrated the feasibility of a single chip JSTE solution based on three processor architecture for carrier beamforming, equalization and demodulation.
