A General Joint Transceiver Design for Multiuser MIMO Channel Equalization

In this paper, joint transmitter receiver filter optimization for channel equalization is investigated for a multiuser multiple input multiple output frequency selective slowly varying channel. Minimum mean square error criterion is used in the equalization under a total transmit power constraint. Because of the simplicity of the optimization of multiple access channel, channel duality is used for the optimization problem and the solution is transformed to the broadcast, interference and MIMO frequency selective channels if required.
