Timing and Multi-path Delay Estimation for Distributed MIMO-OFDM Systems
This paper proposes a timing synchronization algorithm based on Constant Amplitude Zero Auto Correlation (CAZAC) sequences for the distributed the multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. This algorithm designs a new training sequence,and then it is transmited by orthogonal function method in the time domain. And it can not only accurately detect the time offsets,but also accurately estimate the multi-path delays of each transmission antennas. Simulation results indicate that this timing synchronization algorithm can accurately estimate the time offsets and the multi-path delays of each transmission antennas in Rayleigh and AWGN channel It. has a satisfactory performance of the timing estimation in single-path at a low signal-to-noise ratios (SNR).And when the SSR is above 8 DB.the capture probability of multi-path is more than 80％.
