Joint Transmitter-Receiver Design in TDD Multiuser MIMO Systems: An Egocentric/Altruistic Optimization Approach
This contribution considers joint transmitter-receiver design in general multiuser multiple-input multiple-output (MIMO) systems, where uplink and downlink use time-division duplex (TDD). We assume that there exist multiuser interference as well as other jamming signals in the system. The optimization strategy considered in this contribution represents one of the applications of the theory proposed in \cite{Lie-Liang-transmitter-receiver-VTC07-B}, where the transmitters and receivers are respectively optimized in order to achieve their altruistic (O)-optimum and egocentric (E)-optimum solutions. Furthermore, a novel criterion of minimum power distortionless response (MPDR) is proposed for transmitter preprocessing. Our design motivates simple mobile terminals (MTs) with low-complexity. Our study and performance results show that the MPDR-assisted transmitter preprocessing is capable of efficiently suppressing the multiuser interference. However, joint transmitter-receiver optimization is required, in order to suppress the extra jamming signals.

Abstract
This contribution considers joint transmitter-receiver design in general multiuser multiple-input multiple-output (MIMO) systems, where uplink and downlink use time-division duplex (TDD). We assume that there exist multiuser interference as well as other jamming signals in the system. The optimization strategy considered in this contribution represents one of the applications of the theory proposed in \cite{Lie-Liang-transmitter-receiver-VTC07-B}, where the transmitters and receivers are respectively optimized in order to achieve their altruistic (O)-optimum and egocentric (E)-optimum solutions. Furthermore, a novel criterion of minimum power distortionless response (MPDR) is proposed for transmitter preprocessing. Our design motivates simple mobile terminals (MTs) with low-complexity. Our study and performance results show that the MPDR-assisted transmitter preprocessing is capable of efficiently suppressing the multiuser interference. However, joint transmitter-receiver optimization is required, in order to suppress the extra jamming signals.
