Joint Dirty Paper Coding and Linear Receiver Design for Multiuser MIMO Broadcast Channels

【摘要】 <正>A multiuser multiple input multiple output (MIMO) broadcast scheme was proposed through applying dirty paper coding (DPC) at the transmitter and linear equalization at the receiver. Assuming single data stream communication for each user, joint transmitter and linear receiver design were done to enhance the system performance. Furthermore, a multiuser scheduling algorithm was presented to exploit multiuser diversity when the number of the users is larger than that of transmit antennas. The proposed system achieves the sum rate close to the Sato bound and is superior to some of the existing schemes.更多还原
