摘要

本文研究了在不同衰落设置条件下，在超宽带和认知无线电组件(UWB-CR)中实现的多种频谱感知方案。在漏检曲线概率条件下，比较了不同检测器的传感性能。数值模拟结果表明，检测器的选择依赖于场景、检测器的要求和可获得的先验知识。仿真结果表明，利用周期平稳检测算法中的自相关特性，可以在选择频率通道时获得较好的检测性能。

Implementation of Spectrum Sensing Methods for UWB-Cognitive Radio System

In this paper, a number of spectrum sensing schemes implementation in ultra wideband and Cognitive radio component (UWB-CR) under different fading settings condition are studied. The sensing performance of different detectors is compared in conditions of probability of miss detection curves. Numerically simulation results are shown that the selection of detector rely on the scenario, the detector requirements and on the obtainable prior knowledge. Also simulation results can be shown that it is possible to achieve better detection performance in choosing frequency channel by exploiting the autocorrelation in cyclostationary detection algorithm.
