In this paper, we investigate the channel estimation and time synchronization problem based on the zero correlation\nzone (ZCZ) sequence set for single carrier multiple-input multiple-output frequency domain equalization (SC-MIMOFDE).\nA factorized construction of ZCZ sequence set considering the properties of both ZCZ and nonzero correlation\nzone (NCZ) is proposed with efficient generator and correlator, which can be in favor of timing synchronization and\nchannel estimation both in performance and computation complexity. Using the ZCZ sequence set, a new algorithm\ncalled twice section-maximum algorithm is put forward to eliminate energy interference among channels from\ndifferent transmitting antennas to the same receiving antenna. The performance achieved by the developed\nalgorithm which performs joint timing synchronization and channel estimation with lower computational cost is\nbetter than that of the conventional method.
