Optimal Power Allocation for Linear Dispersion Codes Over Correlated MIMO Channels with Channel State Feedback
— The design of spatio-temporal power allocation schemes is considered for space-time coding over spatially correlated multiple-input multiple-output (MIMO) channels. The focus i...

Diversity-Multiplexing Tradeoff in Selective-Fading MIMO Channels
— We establish the optimal diversity-multiplexing (DM) tradeoff of coherent time, frequency and time-frequency selective-fading MIMO channels and provide a code design criterion ...
