Distributed QAM-Based Space-Time Block Codes for Efficient Cooperative Multiple-Access Communication

Distributed space-time block coding schemes based on quadrature amplitude modulation (QAM) symbols are introduced that enable users in a wireless multiple-access relay channel to cooperate with each other in order to improve the reliability of their information in a fair, rate-efficient manner. The...
