二维空间谱的频谱感知技术研究

Spectrum detection technology of two-dimension space spectrum

认知无线电的提出,能够有效地解决目前频谱资源匮乏的问题,频谱感知是认知无线电中必不可少的关键技术之一。着重对低功率复杂无线场景的频谱感知技术进行研究,在待测区域布置大量传感器或阵列天线,对授权用户的信息进行估计,得出区域性的干扰温度估计。

The cognitive radio can efficiently solve the problem of insufficient spectrum resource, and the spectrum detection is one of the key techniques in the cognitive radio. This paper mainly discusses the spectrum detection technique in the lowpower, complex, wireless scene, lay amount of sensor nodes or array antennas in the specified district, estimates the information of the primary user, and gets the regional estimate of interference temperature.
