Abstract :
In this paper, a joint frame detection and timing estimation scheme for burst Orthogonal Frequency Division Multiplexing (OFDM) systems is proposed in double selective channels. The proposed scheme based on the training sequence is not sensitive to carrier frequency offset (CFO) and the given threshold for frame detection is robust to different signal-to-noise ratio (SNR). Simulation results demonstrate that the scheme can work well even if SNR is low.
