A low complexity symbol timing estimator for MIMO systems using two samples per symbol

A new algorithm for data-aided symbol timing estimation in multiple antenna systems is proposed. By utilizing the information about the transmitted pulse, the proposed method achieves better performance and lower computational complexity than the recently proposed discrete Fourier transform (DFT) based interpolation method. Further, the method needs only two samples per symbol which is half of the oversampling factor required by the DFT based interpolation method.
