Abstract

The downlink minimum bit error rate (MBER) transmit beamforming is directly derived based on the uplink MBER receive beamforming for time division duplex (TDD) space-division multiple-access (SDMA) multiple-input multiple-output systems, where the base station (BS) is equipped with multiple antennas to support multiple single-antenna mobile terminals (MTs). It is shown that the relationship between multiuser detection and multiuser transmission can still be applied for the rank-deficient system where the number of users supported is more than the number of transmit antennas available at the BS, if the MBER design is adopted. The proposed MBER transmit beamforming scheme is capable of achieving good performance for rank-deficient TDD-SDMA systems with the support of low-complexity and high power-efficient MTs, and its robustness to the downlink and uplink noise or channel mismatch is verified using simulation.
