Time Domain Channel Estimation for Amplify-and- Forward Relay in OFDM Systems
In this paper, we consider an amplify-and-forward (AF) OFDM relaying system without direct channel between the source node and the destination node. Different from the traditional frequency domain channel estimation, we utilize the special comb-type pilots to perform the time domain processing, and estimate the equivalent end-to-end channel impulse response. Simulation results show that our proposed method can obtain satisfactory performance while it has relatively low complexity.
