Dynamic Spectrum Access in Multi-Hop Wireless Broadband Networks

点击翻译按钮获取中文摘要

Recent studies have shown that significant portions of the licensed spectra are idle most of the time. Cognitive radio is a technology allowing unlicensed devices to use parts of the licensed spectrum not occupied by the licensed devices. In this program we will design communication networks capable of sensing the radio environment and selecting suitable spectral bands for transmission. This program will expand the knowledge of cognitive networks theory by creating new dynamic spectrum access and interference cancellation techniques. The proposed research is significant for improving the radio spectrum usage in Australia and it will have an excellent commercial potential.
