Optimal Diversity Multiplexing Tradeoff Region in Asymmetric Multiple Access Channels

— We consider a multiple access channel (MAC) with multiple antennas, where each user has different diversity and multiplexing gain requirement. For this configuration, we characterize the fundamental tradeoff region for each user. Specifically, we compute the maximum achievable diversity gain for a user in a MAC, given an achievable point in the multiplexing gain region.
