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...

SVD-Aided, Iteratively Detected Spatial Division Multiplexing Using Long-Range Channel Prediction
In this contribution iteratively detected spatial division multiplexing is investigated under the constraint of a fixed data throughput. Existing bit loading and transmit power a...

Multi-Carrier Transmission with Limited Feedback: Power Loading over Sub-Channel Groups
— Feedback of channel state information (CSI) enables a multi-carrier transmitter to optimize the power allocation across sub-channels. We consider a single user feedback scheme ...
