Application of SDMA in GSM

  • Considering the special characters of GSM (Globle System for Mobile) and the method presented by other researchers which uses antenna arrays to eliminate the cochannel interferences in wireless communication, a SDMA (Space Division Multiple Access) architecture used in GSM was put forward. Adaptive array and soft beamforming were used in this method to realize SDMA in TDMA (Time Division Multiple Access) system and no estimation of DOA (Direction of Arrival) or spatial signature was required in advance. This method can produce orthogonal beams in relative mild situation, therefore the same channel can be used by different users simultaneously. The applicability of this method was verified through simulation.
