浅析感知无线电技术中的频谱感测技术

在无线电技术飞速发展的今天，通信技术以互联网为载体已促进了经济转型和快速增长。无线频谱传输的需求正在逐日的增加，因此，加大无线通信系统的研究力度是非常必要的。科学研究者想要对频谱资源进行有效规划以及利用，必须从提升核心技术的角度出发，建立并逐步发展综合通信系统的分布和共享频谱。也就是说，整个系统高效地实现频谱的最优分配是无线通信技术发展的不竭动力。因此，本文从认知无线电技术的定义入手，探讨了认知无线电技术中的频谱感知技术，有效利用频谱资源则可对未来无线电技术提供一定的有益参考。

A brief study of the spectrum sensing technology in radio communication

With the incredible boom, the radio communication nowadays has promoted the development and the transformation of economy taking internet as the carrier. However, since the need of wireless spectrum transmission increases drastically, strengthening the research of radio communication system is absolutely necessary. Therefore, scientists of this field must try to establish the share and distribution mechanism of spectrum from the perspective of improving the core technology if they want to project and utilize this limited resource in an effective way. Namely, the system itself is the fundamental impetus for the high efficiency of utilization and the optimization of spectrum. Thus, the study in this paper discusses in brief the spectrum sensing technology from the definition of radio communication, so as to provide certain reference for the development of radio communication, in the sense of effective utilization of spectrum resources.
