Abstract

On the uplink of an SDMA mobile radio system K>1 users are transmitting in the same frequency band and time slot. These signals are received at the base station with an array of M⩾K antennas. A complete base station receiver structure to jointly detect the bits transmitted by the K users is presented. To guarantee a good receiver performance a DOA-sensitive channel allocation scheme is described. The feasibility of the concept is proved by extensive simulations in realistically modelled 3D mobile radio channels
