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，许可频谱的很大一部分在大部分时间是空闲的。认知无线电是一种允许未授权设备使用未被授权设备占用的部分授权频谱的技术。在这个项目中，我们将设计能够感知无线电环境并选择合适的频谱进行传输的通信网络。该计划将通过创建新的动态频谱接入和干扰消除技术来扩展认知网络理论的知识。该研究对提高澳大利亚的无线电频谱利用率具有重要意义，具有很好的商业潜力。
