Description: 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 of different
channels based on history information helps a cognitive radio
(CR) to select the best channels for control and data
transmission. Different prediction rules apply to periodic and
stochastic ON-OFF patterns. A CR can learn the patterns in
different channels over time. We propose a simple classification
and learning method to detect the pattern type and to gather the
needed information for intelligent channel selection. Matlab
simulations show that the proposed method outperforms
opportunistic random channel selection both with stochastic and
periodic channel patterns. The amount of channel switches
needed over time reduces up to 55 , which reduces also the
delay and increases the throughput. Platform: |

Description: This folder Contains one file file of code of cognitive femtocell, second computing distance and third also computing path loss.
We consider smart “cognitive” femtocells, that can
decode the base station control channel and make decision on
their transmission opportunities based on the scheduling and
resource allocation of the overlaying macrocell. The operation
of such femtocells is somehow reminiscent of “Type II” relays,
as specified in the IEEE 802.16j standard. Under certain system
assumptions, we consider the tradeoff region of the macrocell
versus aggregate femtocell throughput Platform: |

Description: This paper illustrates the results of the throughput of Secondary User (SU) in cognitive radios under
cooperative scenario with the use of evolutionary algorithms in the presence of additive white Gaussian (AWGN)
noise. In this work, the performance of half-voting and OR fusion rule is studied in terms of Pd Vs Pf curves. OR fusion
rule is found to be most suitable in cooperative scenario. Platform: |

Description: Cognitive radio (CR) is of special significance to improve spectrum utilization, and spectrum allocation is one of the key technologies in the realization of cognitive radio. The spectrum allocation problem considered in this paper aims to maximize the throughput of the second users (SUs) within the transmit power limit of SUs and the PU interference constraint.
