A Novel Timing and Frequency Synchronization Scheme for MIMO OFDM System

摘要：

This paper proposes a fast and reliable technique for timing and frequency synchronization of multiple-input multipleoutput (MIMO) orthogonal frequency division multiplexing (OFDM) systems. The synchronization is achieved using one chu sequence-based preamble which is simultaneously transmitted from all transmit antennas in the same OFDM time instant. From analysis, the chu sequence-based preamble gives better detection properties in terms of higher right timing detection probability and accurate fractional frequency synchronization even at a low SNR and in a frequency selective channel. Furthermore, application of the proposed algorithm can obtain the integral frequency offset in time domain.
