Cooperative diversity is widely used in wireless communication. Because of its own unique advantages, we try to combine Cooperative diversity with OFDM. Key technologies of OFDM, three methods of channel estimation, two types of cooperation, and two combining methods in OFDM system are presented in this paper. Simulations of OFDM cooperative diversity system with two combining methods are performed. The performances of OFDM cooperative diversity system under three methods of channel estimation are simulated and analyzed respectively.
