Description: Spectrum sensing is a key technology in Cognitive
Radio (CR). It provides the CR system with available vacant
channels list by sensing the spectrum environment over a wide
frequency band. However, local sensing by single node will be
compromised if the sensing node experiences shadowing or
fading effect. Cooperative spectrum sensing is derived to solve
this problem Platform: |

Description: 谱感知技术是认知无线电(CR)的关键技术,频谱检测的可靠度和精度决定了是否会影响主用户的正常通信及认知用户能否有效利用频谱.在频谱检测的众多方法中,能量检测法是一种常用的方法,但能量检测器的门限很容易受到噪声功率变化的影响,影响主用户的正常通信.笔者提出一种自适应背景噪声的门限设置方法,通过引入门限评价指数作为衡量频谱感知效率和频谱资源利用率的度量指标,使得认知用户在不同的应用环境中能自适应地设置频谱感知门限,达到更充分利用频谱资源和更有效传送信号的目的.仿真证明,该方法确定的门限能够随着噪声条件的改变而改变,显著提高了能量感知方案的性能.-Spectrum sensing technology is the key technology of the cognitive radio(CR),the reliability and accuracy of the spectrum detection decides whether it will affect the normal communication of the main users and the utilization of spectrum of the cognitive users.Among the many methods of spectrum detection,energy detection is a commonly used method.However,in practice,the uncertainty of noise interference makes the setting of the threshold difficult,causing an interruption of the communication of the main use Platform: |
