In the last decades, 未经许可的频段已经变得拥挤不堪, 由于无线通信和网络创新的激增. 相比之下，许可频谱的利用率却相当低. 这两个观察结果促使业界和频谱管理机构推动动态频谱接入，使未授权用户可以动态检测和访问空闲的授权频段, 大幅提高频谱利用率，鼓励无线通信创新.
However, 现有的动态频谱访问范式在主用户和辅助用户(辅助用户)之间强加了一种“敌人”关系。, 当频谱只被主用户或从用户使用时. In particular, 当主用户停止使用该频谱时，从用户才可以接入该频谱, 主用户流量的复苏扰乱了次用户流量. 这种模式没有为主要用户提供足够的激励来接受动态频谱接入. Furthermore, 遵守严格的动态频谱接入策略, 次要用户需要保守地感知和访问频谱, 导致实际频谱利用率明显低于可行的频谱利用率. In this project, 我们提出了新的动态频谱接入架构，为主要用户提供激励, 使主用用户和从用用户都能从动态频谱接入中获益. 我们进一步设计算法和协议，以提高认知无线电网络中动态频谱接入的性能.
