Recently, the orthogonal code-based block transmission (OCBT) systems have been proposed to fulfill the explosive growth of traffic demands. The multi-carrier-based structure of OCBT, however, requires accurate synchronization to combat inter-symbol interference (ISI) and inter-carrier interference (ICI). Fortunately, the repetitive pattern contained in the OCBT symbol enables this synchronization without preambles. In this paper, we propose a novel time-frequency offset estimation method based on the repetition characteristic. Simulation results demonstrate that the proposed estimator provides acceptable root-mean-square error (RMSE) performance. Moreover, we verify that the OCBT systems with the proposed method achieve remarkable throughput enhancement compared with conventional OFDM systems.
