DMT achieving Distributed Space Time Codes for the Multiple Access Channel

The multiple access channel without channel side information at the transmitters is considered here. We propose a family of short distributed structured space-time codes able to achieve the Diversity-Multiplexing gain tradeoff of such a channel.
