Abstract

Synchronization is important in order to correctly recover information for multi-antenna Orthogonal Frequency Division Multiplexing (OFDM) system. In this paper a novel transmitting diversity scheme named as Maximal Channel Power (MaxCP) is proposed. Specifically the channel state information (CSI) is feedback to transmitter firstly and then only one of transmit antennas with the highest channel power is selected. Thus synchronization sequence is only transmitted at the selected antenna. By simulation, it is found that the proposed MaxCP scheme has the better performance than conventional Maximal Ratio Combining (MRC) scheme, in both timing and frequency synchronization for OFDM systems.
