A Review on Digital Modulation in 4G LTE/4G LTE Advanced

EasyChair Preprint 7612

Abstract

Since the last century, mobile telephony has taken an important role in telecommunications, increasing the volume of data traffic supported by its network over the years. From 2.5G telephony experienced the use of data to be used on the internet and in the following generations passing through 3G, 4G and 5G the speed rate has increased. In this sense, this paper presents the evolution of mobile phone technologies, specifically the fourth generation (4G), also called LTE (Long Term Evolution). It also explains the relevance of using digital modulations that work in conjunction with OFDM in 4G to achieve high data rates combined with MIMO systems for this purpose.

Keyphrases: 4G networks, OFDMA, QAM, QPSK, Telecommunications.
