— 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 ...
In xDSL systems, crosstalk can be separated into two categories, namely in-domain crosstalk and out-of-domain crosstalk. Indomain crosstalk is also refered to as self crosstalk. Ou...

Abstract— An optimization algorithm for finding user allocation, bit and power loading in the downlink of MIMO-OFDM systems is proposed. The algorithm represents a generalizatio...
An analytical framework for performance analysis and optimization of coded V-BLAST is developed. Average power and/or rate allocations to minimize the outage probability as well as...
