Comunicación Basada en Radio Cognitiva sobre Radio Definido por Software

Abstract

In this era of wireless technology, the scarcity of radio spectrum poses a serious dilemma for service providers and telecom operators. Cognitive Radio (CR) technology provides an innovative solution to significantly improve spectrum utilization. This document develops and provides the necessary information to implement a communication link based on Cognitive Radio. Tools such as GNU Radio software were used to carry out this task with the implementation of the communication system that contained the selected spectrum detector. It also revealed the main characteristic of the RC technology, which is, to be aware of the radio electric environment, to optimize it and, based on it, make transmission decisions that do not interrupt the communication of the link at any time or hinder or harm the communication of a primary or licensed User. Likewise, Software Defined Radio (SDR) tools were used. They perform radio communication tasks such as baseband processing and the different necessary settings for radio communication in the Ultra High Frequency (UHF) band, thus establishing a link of communication based on Cognitive Radio.
