Research of Cooperative Diversity Applied in OFDM System

摘要：

In recent years cooperative diversity has been widely used in wireless network, and Orthogonal frequency division multiplexing (OFDM) is a key technique of multicarrier transmission to meet high data rate requirement of wireless communication. The aim of this project is to combine the technology of OFDM with cooperative diversity techniques, in this project, we have done simulation in matlab and compare the performances of the system while the cooperation node employs AF cooperative scheme contrast with DF cooperative scheme. The simulation results show that the OFDM system with Cooperative Diversity has a better performance when the cooperation node employs DF cooperative scheme.
