Performance evaluation of time-hopping sequence for rapid on-off-division duplex

This paper introduces a time-hopping (TH) system for rapid on-off-division duplex (RODD), with this method, virtual full-duplex communication at the frame transmission level can be realized. However because of the randomness of the transmission timing, the slots may have a collision with a high probability. So it's very important to establish a model to calculate the collision ratio, and analyze the performance of the time-hopping patterns by calculating its Hamming correlation function. This paper presents an RODD prototype and designs a collision model for time-hopping transmission. The simulation results indicate that a proper designed time-hopping pattern can reduce the packet error rate (PER) of RODD system.
