【Abstract】 A scheme of joint transmission(JT) based on multi-user MIMO-OFDM is proposed in this paper.The system model is given,and the algorithms for the data transmission and detection are derived.The receiver’s calculation cost for multi-user MIMO-OFDM downlink is reduced significantly with this scheme.The results of simulation and analysis in the TDSCDMA system are presented,which indicate the BER of the JT technique based on multi-user MIMO-OFDM is lower than that of JT technique based on multi-user MIMO.更多还原
