A cooperative communication system using cross-layer coding method base on Hybrid-ARQ

MIMO system generally requires more than one antenna at the communication device. However, many wireless devices are limited by size, cost or hardware complexity to one antenna. To overcome such restrictions, we used a new technique, called cooperative communication. We propose a new cooperative transmission strategy system using cross-layer coding method base on H-ARQ for optimal communication. And we confirmed simulation result better performance than general one by one communication in using proposed cooperative communication system.
