This paper extends the complexity analysis [1]-[3] for MIMO point-to-point systems, to the case of the multiple access channel (MAC). Specifically we derive upper bounds on
the complexity exponent required to achieve the optimal diversity multiplexing-gain tradeoff (DMT) performance dmac(r) of the symmetric MAC with K single antenna transmitters and a receiver having nr antennas. Finally we show how utilizing a
few bits of feedback to allow for user selection, can in fact result in substantial complexity reductions, while at the same time improving the DMT performance.
