摘要:
We first investigate the effect of the timing offset on the frequency offset estimation in orthogonal frequency division multiplexing (OFDM) systems. Then, we propose an efficient frequency offset estimation scheme using the coherence phase bandwidth (CPB) and a threshold in the presence of the timing offset. The numerical results demonstrate that the proposed scheme has lower computational complexity compared with the conventional schemes and performs robust operation in the presence of the timing offset. http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=1625512
