Abstract

Wireless technology is the most important technique for transferring informationsignals without using cable. Wireless is used for mobile telephones, wireless datacommunication such as Wi-Fi, cellular data service, mobile satellite communicationand wireless sensor networks. Other than these applications, wireless technologyis used for medical technologies and computer interface devices. In wireless datacommunication systems, high data rates and quality services are demanded moreday by day. For this reason, under the practicability constraint, new developments orcombination of old techniques must be studied. In this thesis work, adaptive modulationand coding is combined with cooperative communications. Adaptive modulationand coding is already used in many wireless data communication systems suchas EDGE, HSPA and Wi-Fi. Cooperative communication is shown that transmissionperformance can be enhanced.
