Improving orthogonal space-time block codes by utilizing quantized feedback information
George Jöngren, Mikael Skoglund · 2002
We propose a transmission scheme which utilizes vector quantized channel information obtained from a feedback link for improving a space-time code. The result is a transmission method which provides robustness to the non-perfect nature of the channel information while combining the benefits of conventional beamforming with those given by space-time coding.
