Diseño de un algoritmo para el análisis y monitoreo de parámetros de señales LTE 4G utilizando la plataforma de radio definido por software (USRP).

Abstract

The present research is focused on the design of an algorithm for monitoring signals 4G LTE, which is a technology in our country, which currently only has the public company CNT EP and in the coming months private companies OTECEL CONECEL and can reach transfer speeds greater than 100 Mbps data whenever there is a good signal condition, a bandwidth of 1.4 MHz to 20 MHz and a modulation scheme QPSK and QAM. The main components of the device which has transmitting and receiving RF programmable and development (SDR) NI USRP called 2920 work allowing frequencies 1.7 GHz to 2.1GHz using LTE 4G cellular technology, and the algorithm is designed with LabVIEW software from National Instrument owner that has all the necessary tools and virtual tools, whose sole task, measuring parameters LTE radio spectrum signals and signal transmission. This system is mainly used as a tool of analysis, and provide students with career telecommunications a new element of learning.
