The use of digital antenna arrays to increase the efficiency of a communication link is studied. Specifically, a Time Reference Multi-beamformer/conformer system, is proposed. The goal is the simultaneous demodulation of BPSK-users, regardless their co-channel nature (in frequency and time). For this purpose, the proposed system resorts to the statistical independence of the impinging user signals and to the spatial diversity introduced by the array. A robust High Order Statistics Combiner will be developed. Its potential stands out in the presented simulations, which illustrate the good performance of the designed multiuser system both in the acquisition and tracking.
