%X In the paper, a novel overlapping multiplexing technology named OvHDM (Overlapped Hybrid Division Multiplexing) is proposed. In OvHDM, the overlapping multiplexing is developed in both time and frequency domain. The optimum detection, spectrum efficiency, detection complexity, performance and Peak-to-Average Power Ratio (PAPR) of OvHDM are studied in detail. The signal model of OvHDM is the convolutional constraint model between vectors. In order to implement optimum detection, a novel algorithm named MU-MLSD (Multi-User Maximum-Likelihood Sequence Detection) is proposed. The simulation results prove that the performance of OvHDM is better 4.5dB than that of 64QAM and better 1.5dB than that of OvTDM (Overlapped Time Division Multiplexing) when the spectrum efficiency is 6bit/s/Hz. Meanwhile, the PAPR of OvHDM is better 2dB than that of 128-subcarrier OFDM and better 2.6dB than that of 1024-subcarrier OFDM.
