Abstract

In this paper, a virtual full-duplex system is designed by combining rapid on-off division duplex (RODD) and time-frequency hopping (TFH) system. In order to solve the inconsistency of communication quality caused by fixed time-frequency hopping parameters in this model in different network environments, an adaptive time-frequency resource management algorithm is proposed. In the algorithm, the RODD codebook is generated based on optimized logistic map, the duty cycle and collision ratio are calculated by using the channel detection algorithm optimized based on double-threshold and forward consecutive mean excision (FCME) algorithm, and the duty cycles suitable for the current environment are selected by combining packet error ratio, node throughput and network topology as parameters input. The simulation results show that the adaptive time-frequency resource management algorithm proposed in this paper can keep the collision ratio at a low level all the time, and can effectively avoid packet loss and packet error caused by excessive collision ratio.
