摘要：
A short-time Fourier Transformation (STFT) based 2D blind time and frequency synchronization scheme is proposed for MIMO and Multi-User OFDM systems. By analyzing the short-time 2-D time-frequency amplitude spectrum, intervals where no inter-symbol interference (ISI) exists are checked out for symbol synchronization, and samples during these intervals are used to carry out carrier frequency offset. Theoretical analysis and simulation results show that the proposed method is more robust and provides more accurate estimation of carrier frequency offset than traditional schemes.
