Timing synchronisation method for MIMO-OFDM system using orthogonal preamble

Abstract

The benefits of OFDM (Orthogonal Frequency Division Multiplexing) include resistance against RF interference, high spectral efficiency and lower multipath distortion, while MIMO (Multi-Input Multi-Output) system increases the bandwidth due to the propagation of signals using multiple transmit antennas. The timing synchronization in MIMO-OFDM system, is the main challenge in order to detect the header of each received frame. In this paper, a new timing synchronization method based on orthogonal codes is proposed. Simulation results, for the proposed method, show a good performance for timing synchronisation for MIMO-OFDM system by using some LTE parameters.
