In this study, we study compressive channel estimation for Orthogonal Frequency Division
Multiplexing (OFDM) modulated Amplify-and-Forward (AF) relay networks. Based upon the mathematical
channel model of P2P and sparseness measure function, by using Monte-Carlo runs, we show that the OFDM
cooperation convoluted channels also exhibit sparsity. In this study, we propose two compressive channel
estimation methods to exploit the inherent sparse structure in multipath fading channels of OFDM cooperation
networks with Amplify-and-Forward (AF) relays, Simulation results demonstrate that the proposed compressive
channel estimation methods provide significant improvement in mean square error (MSE) performance
compared with the conventional channel estimation methods.
Key words: Amplify-and-Forward (AF), cooperation networks, Compressive Sensing (CS), multipath fading channel, Orthogonal Frequency Division Multiplexing (OFDM), ,
