Spatial Multiplexing Architectures with Jointly Designed Rate-Tailoring and Ordered BLAST Decoding - Part I: Diversity-Multiplex
Abstract-- The V-BLAST (vertical Bell Labs layered Space-Time) architecture involves independent coding/decoding per antenna (layer) with equal rate and power per antenna and a fix...

On Finite-SNR Diversity-Multiplexing Tradeoff
— Diversity–multiplexing tradeoff (DMT) presents a compact framework to compare various MIMO systems and channels in terms of the two main advantages they provide (i.e. high da...

Signal space diversity for spatial multiplexing
— When channel state information is available at the transmitter, we can diagonalize a MIMO channel with SVD transceivers. However, outage of the weaker eigenchannels limits the ...

Two Models for Noisy Feedback in MIMO Channels
Two distinct models of feedback, suited for FDD (Frequency Division Duplex) and TDD (Frequency Division Duplex) systems respectively, have been widely studied in the literature. In...

Power-controlled feedback and training for two-way MIMO channels
Most communication systems use some form of feedback, often related to channel state information. The common models used in analyses either assume perfect channel state information...
