Blind timing algorithm on multiple bases cooperation MIMO-OFDM system
Yong Xiong · Systems engineering and electronics · 2010
A blind timing synchronization method using the cyclostationary feature of received signals of multiple bases cooperation multiple input multiple output(MIMO) orthogonal frequency division multiplexing(OFDM) transmission systems is proposed.Owing to the shift of the received signal cyclic autocorrelation peak,the delay difference among antennas is derived.A detection method based on sliding-window is designed to get the timing delay of each antenna.The simulation results prove this method can sovle the problem of ditributed multiple antennas timing synchronization with acceptable complexity.
