Abstract:By exploiting spatial characteristics of MIMO wireless channel, the time synchronization algorithm based on single symbol for MIMO-OFDM systems is presented. This algorithm is able to overcome the deep fading of received signal due to multipath in wireless environments. The mathematical expression of error probability of timing synchronization is derived. The simulation results are given in wireless multipath channel and verify the performance improvement.
Keywords:MIMO-OFDM
