Performance analysis of MIMO JT schemes based on energy effciency

For the downlink of multi-user MIMO joint transmission (JT) schemes is proposed, which can be classified as receiver (Rx) oriented. Firstly, we introduce a generic multi-user MIMO JT downlink transmission model. Up to now most research work focuses on linear signal processing algorithms, such as TXZF, TXMF and TXMMSE. In what follows we do compare the above three algorithms based on energy efficient and BER criterion. Simulation results prove the feasibility of linear TXZF algorithm in multi-user MIMO JT downlink.
