Integrated data and energy transfer (IDET) enables the electromagnetic waves to transmit wireless energy at the same time of data delivery for low-power devices. In this paper, an energy harvesting modulation (EHM) assisted multi-user IDET system is studied, where all the received signals at the users are exploited for energy harvesting without the degradation of wireless data transfer (WDT) performance. The joint IDET performance is then analysed theoretically by conceiving a practical time-dependent wireless channel. With the aid of the AO based algorithm, the average effective data rate among users are maximized by ensuring the BER and the wireless energy transfer (WET) performance. Simulation results validate and evaluate the IDET performance of the EHM assisted system, which also demonstrates that the optimal number of user clusters and IDET time slots should be allocated, in order to improve the WET and WDT performance.
