Cooperative Transmission Through Incremental Redundancy

Rapid development of wireless networks leads to unceasing appearance of new techniques and methods. Recently cooperative relaying emerged as viable and tempting option for future wireless networks. Cooperative transmission attempts to provide spatial diversity for hardware devices that have only one antenna through the joint use of antennas that belong to several nodes. An overview of approaches in this area is presented. For proposed coded cooperative strategy, regions for which cooperation results in a gain in Frame Error Rate (FER) are analyzed.
