Abstract :
This paper proposes an improved synchronization and channel estimation solution for multi-input multi-output orthogonal frequency division multiplex (MIMO-OFDM) system. We present a novel preamble design, on this basis, the performance of synchronization and channel estimation can be improved in an iterative way. Simulation results demonstrate that the proposed algorithm have a satisfactory performance even at low SNR in rich multipath, fast moving environment.
