    Abstract
  • To achieve virtual full-duplex (VFD) communication using half-duplex radios, the rapid on-off-division (RODD) technique has been proposed in recent years. The time-hopping (TH) sequence is critical to controlling self-interference introduced in the paradigm. By constructing the collision model with a symbol level time scale, the periodic collision correlation function properties are introduced as the performance metric for the TH sequence in the RODD system. To achieve the best VFD performance, an optimization-based method for TH sequence design is proposed. In addition, the conventional TH frame structure design for RODD system is improved. Numerical simulations are presented to demonstrate that the proposed approach can significantly increase system performance. Results indicate that the TH sequence design is very effective for the RODD system.
