The Impact of CSI and Power Allocation on Relay Channel Capacity and Cooperation Strategies
Capacity gain from transmitter and receiver cooperation are compared in a relay network where the cooperating nodes are close together. Under quasi-static channels, when all nodes...

Quasi-Optimal Channel Assignment for Real-Time Video in OFDM Wireless Systems
In this paper, real-time video transmission with quality of service (QoS) assurance over orthogonal frequency division multiplexing (OFDM) wireless systems is studied. Three quasi-...

Codeword-Independent Performance of Nonbinary Linear Codes Under Linear-Programming and Sum-Product Decoding
A coded modulation system is considered in which nonbinary coded symbols are mapped directly to nonbinary modulation signals. It is proved that if the modulator-channel combination...
