摘要:Smart or adaptive antennas promise to provide significant increases in system capacity and performance in wireless communication systems. Multiuser detectors have the capacity of eliminating MAI, the near- far problem and providing a significant capacity increase. In order to gain from the enhancements of both: multiuser detection and adaptive antenna. We propose in this paper to combine both schemes for an asynchronous systems.Our analysis is based on modeling the angular gain of the spatial filter (array beam pattern) by a piece-line function that approximates the passband (or in-beam) and the stopband (or out-beam) with an equivalent attenuation. The proposed model conforms the benefits of adaptive antennas in reducing the overall interference level (intercell/intracell) and to find an accurate approximation of the error probability.
