Análisis del rendimiento de los canales de la capa física PDSCH y PUSCH mediante el toolbox 5g de Matlab.

Abstract

Cellular networks continue to evolve over the years, features have been changing and data speed is increasingly prioritized. The need for applications with high data rates is solved with 5G. This degree work will focus on the study of the throughput of 5G uplink and downlink shared physical channels through simulations implemented with Matlab software. A brief introduction to 5G is given to understand the network's theoretical foundation, including network architecture, technologies related to data transmission, physical layer channels and signals, expected applications, and channel models. It also continues with the description of the code used in the simulations. The Matlab 5G Toolbox functions and objects used in the simulation scripts are described. With the results of the simulations, comparisons and analysis of the curves that are a function of rate (Mbps) vs dB are performed. The parameters that are varied in the simulations are the number of resource blocks, the subcarriers spacing, modulation schemes, and the number of antennas.
