In this paper, we consider the joint design of the transceivers for amultiple access Multiple Input and Multiple Output (MIMO) system havingInter-Symbol Interference (ISI) channels. The system we consider is equippedwith the Minimum Mean Square Error (MMSE) Decision-Feedback (DF) detector.Traditionally, transmitter designs for this system have been based onconstraints of either the transmission power or thesignal-to-interference-and-noise ratio (SINR) for each user. Here, we explore anovel perspective and examine a transceiver design which is based on a fixedsum mutual information constraint and minimizes the arithmetic average of meansquare error of MMSE-decision feedback detection. For this optimizationproblem, a closed-form solution is obtained and is achieved if and only if theaveraged sum mutual information is uniformly distributed over each activesubchannel. Meanwhile, the mutual information of the currently detected user isuniformly distributed over each individual symbol within the block signal ofthe user, assuming all the previous user signals have been perfectly detected.
