SR-ARQ for MIMO OFDM Systems with Channel State Information Only at the Receiver
— In this paper, we compare two selective-repeat automatic-repeat-request (SR-ARQ) protocols for spatial multiplexing multiple-input multiple-output (MIMO) orthogonal frequency-d...

Optimum MIMO-OFDM Receivers with Imperfect Channel State Information
—Channel estimation inaccuracy is known to affect significantly the error performance of coded communication systems. This applies in particular to broadband MIMO channels, ofte...

Optimum and Suboptimum Receivers for Space-Time Coded Systems in Correlated Fading
Abstract — We consider a space-time coded system in a correlated Rayleigh flat fading environment. The channel state information (CSI) is obtained from the known pilot code matr...

Dirty-Paper Coding without Channel Information at the Transmitter and Imperfect Estimation at the Receiver
—In this paper, we examine the effects of imperfect channel estimation at the receiver and no channel knowledge at the transmitter on the capacity of the fading Costa’s channel...

Effects of Imperfect Channel State Information on Achievable Rates of Precoded Multi-User MIMO Broadcast Channels with Limited F
—We consider multi-user MIMO broadcast channels with limited feedback. A recently proposed linear precoding technique, regularized block diagonalization (RBD), is used to mitigat...
