- 基于信道的历史信息来预测不同信道的未来可用时间可以帮助CR选择一个最佳信道进行信息传递。不同的预测准则应用到周期或是随机的开关模式中。一个CR可以学习以往不同信道的模式。我们提出一个简单的分类和学习方法去检测模式的类型和收集需要的信息用于智能信道的选择。MATLAB仿真结果显示提出的方案在随机信道的随机和周期模式中都有优越的表现。随着时间的变化，新到的切换次数减少到55 ，并且延迟时间也相应减少，而吞吐量却在提高。-Prediction of future availability times

- 噪声功率比(NPR)这个概念自频分多路复用(FDM)电话系统诞生之初即已出现。简单而 言，NPR用于衡量多通道系统中当其他通道上存在随机活动时，某个闲置通道的“安静”程 度。噪声和交调失真产物进入该闲置通道，从而降低性能。该概念最初用来检查FDM链 路中的4 kHz宽语音通道，如今，在确定多通道宽带通信系统的特性时也是有用的——但在 现代测量技术方面，存在一些重要的区别。-The concept of the noise power ratio (NPR) from the fr
