Opportunistic channel access scheme for cognitive radio system based on residual white space distribution
We propose an opportunistic channel access scheme for cognitive radio-enabled secondary networks. In our work, we model the channel occupancy due to Primary User (PU) activity as a...

Self-optimizing routing in MANETs with multi-class flows
In this paper we show how game theory and Gibbs sampling techniques can be used to design a self-optimizing algorithm for minimizing end-to-end delays for all flows in a multi-clas...

Euclidean distance decomposition to generate new 16-QAM and 64-QAM space-time trellis codes
In this paper, the generation of 16-QAM and 64-QAM space-time trellis codes (STTCs) for several transmit antennas is considered. The main problem with an exhaustive search is the i...
