摘要

本文重点研究了认知无线电(CR)网络中专用感知接收机(DSR)的总感知时间。为了最大限度地减少总感知时间，即接收机感知频谱所花费的时间，对基本的认知无线电接收机结构进行了潜在的修改。认知无线电是一种新型的通信网络，它可以在未被许可用户使用的情况下使未许可用户利用许可频谱。为了减少DSR的感知时间，我们在认知无线电中增加了用于DSR的天线数量。对于各种潜在的应用，所使用的频率范围在很大程度上增加了。

Improvement in Total Sensing Time of the Receiver in the Cognitive Radio

This paper is emphasized on the total sensing time of the dedicated sensing receiver (DSR) of the cognitive radio (CR) network. To minimize the total sensing tine that is the time taken by the receiver to sense the spectrum, a potential modification has been made in the basic cognitive radio receiver architecture. The cognitive radio is a novel communication network, which is useful in utilizing the licensed spectrum by the unlicensed users when it is not being used by the licensed users. In order to reduce the sensing time of DSR, we have increased the number of antennas being used for DSR in the cognitive radio. The range of frequencies being utilized is increased to a large extent for various potential applications.
