| Abstract: | Multiple-Input Multiple-Output(MIMO)is a new technique for wireless communication.Now the research on HF communication systems using MIMO technique to improve the data rate and reliability has been developed.This paper investigates the frequency synchronization for MIMO OFDM HF wireless communication systems,and proposes a frequency synchronization acquisition method by training symbols which are orthogonal in frequency domain in case that multiple frequency offsets exist between the pairs of transmit and receive antennas. |
