TLDR
The optimal tradeoff between diversity gain and multiplexing gain for multiple-input multiple-output (MIMO) channels has been studied recently under the independently identically distributed Rayleigh fading assumption and the results are extended and derived.Abstract:
The optimal tradeoff between diversity gain and multiplexing gain for multiple-inputmultiple-output (MIMO) channels has been studied recently under the independent and identically distributed (i.i.d.) Rayleigh-fading assumption. In this correspondence, this result is extended and the optimal tradeoff performance is derived for generalized fading channel conditions, including different fading types, nonidentical fading distributions, spatial correlation, and nonzero channel means. Our results include many known models as special cases and shed light on the effects of different channel parameters on the optimal tradeoff performanceread more

Diversity–Multiplexing Tradeoff and Outage Performance for Rician MIMO Channels
TL;DR: The DMT characteristics of Rayleigh and Rician channels are shown to be identical and the maximum diversity gain can be achieved at some finite SNR-the maximum gain tends to increase linearly with the Rician factor.

Sphere Decoding Complexity Exponent for Decoding Full-Rate Codes Over the Quasi-Static MIMO Channel
Joakim Jalden,Petros Elia +1 more
TL;DR: The recently introduced threaded cyclic-division-algebra-based codes are shown to take a particularly concise form as a non-monotonic function of the multiplexing gain, which describes the minimum known complexity of any decoder that can provably achieve a gap to maximum likelihood performance that vanishes in the high SNR limit.
