- 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

- 在3.49-3.51GHZ频段内的典型中国城市环境下，地面信号衰落仍服从经典的指数对数分布。在中度误差（σx =10.291）下，路损指数在3.1-3.7之间。半径2公里的小区内，RMS时延在3-4微秒之间；典型的办公室环境中，存在直达径时RMS时延小于0.1微秒。在城市环境中，多径现象很明显，主要由高层建筑物引起，并以簇的方式存在。在城市中低速移动条件下（接收机移动速度小于100 Km/h）某一强径的生存时间通常超过10分钟，但相对到达时间会发生滑动。单一小区内的传播环境具有一定相关性，如果存
