Abstract
A novel algorithm for joint blind CFO and STO estimation based on cyclostationarity of received signal is proposed in a 2×22×2 distributed MIMO-OFDM system. The cyclic correlation of received signal in different nonzero cyclic frequencies is exploited for solution of all STOs, and ESPRIT is used for the estimation of all CFOs between every pair of receive and transmit antennas. Theory analysis shows that the blind algorithm adapts to the synchronization under any distributed stationary noise. Simulation results verify that the performance of the proposed algorithm can keep stableness at low SNR.
