Cognitive-Radio
说明： 利用通信系统中调制信号的循环平稳特性,对频谱空洞进行检测,提升频谱感知技术在低信噪比下的性能。实验结果表明:与传统能量检测方法相比,采用循环特征检测方法改善了认知无线电中频谱空洞的检测能力。(Based on the cyclostationarity of modulation signals, spectrum hole is detected, aiming at the improve- ment of the performance of spectrum sensing in low SNR situation. The results show that comparing with the tra- ditional energy detection technique, cyclostationarity-based spectrum sensing technique has greatly improved the detective ability in cognitive radio.)
