Space-time (ST) coding has emerged as an effective strategy to enhance performance of wireless communications in fading environments. Many different ST coding schemes have been proposed to achieve reliable communications in independent fading channels. However, a design of robust ST codes for correlated fading channels has not been addressed. In this paper, we propose a simple robust ST coding ...

Multiple-input multiple-output (MIMO) wireless communication systems have been studied a lot in the last ten years. They have many promising features like array gain, diversity gain, spatial multiplexing gain, interference reduction, and improved capacity as compared to a single-input single-output (SISO) systems. However, the increasing demand of high data-rate in current wireless communicatio...

Space-time codes have been designed over the last decade to enhance the reliability of open-loop fading wireless systems. However, recent technological advances have enabled the possibility of low-rate feedback from the receiver to the transmitter. The focus of this work is on the implications of this feedback in a point-to-point MIMO system with a coherent receiver and a general model for spat...
