Link-optimal space-time processing with multiple transmit and receive antennas

摘要: Previous information theory results have demonstrated the enormous capacity potential of wireless communication systems with multiple transmit and receive antennas. To exploit this potential, a number space-time architectures been proposed which parallel data streams, simultaneously on same frequency, in multiple-input multiple-output fashion. With sufficient multipath propagation, these different streams can be separated at receiver. Mostly, schemes studied only presence spatially white noise. We present an architecture that is optimal, sense maximum link spectral efficiency, colored interference. evaluate new compare it, under various propagation conditions, to other adaptive-antenna techniques equal
