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.

最近的研究表明，大多数情况下，大部分许可光谱都是闲置的。认知无线电是一项允许未经许可的设备使用许可设备未占用的许可光谱的一部分。在此程序中，我们将设计能够感知无线电环境并选择合适的光谱带进行传输的通信网络。该程序将通过创建新的动态频谱访问和干扰取消技术来扩展认知网络理论的知识。拟议的研究对于改善澳大利亚的无线电频谱使用量很重要，它将具有极好的商业潜力。
