Implementación del sistema WCDMA utilizando esquemas de modulación digital en redes inalámbricas móviles.

Abstract

This document presents the implementation of the WCDMA system using digital modulation schemes in mobile wireless networks. Chapter 2 introduces the generations of mobile wireless communications and radio access techniques such as WCDMA mobile technology. This system works in 3rd generation (3G) mobile wireless communications and that even in the country addresses high-level demands and challenges, helping to provide efficient and promising services that meet requirements such as data, video and multimedia traffic very fast as well as voice signals. In chapter 3 the performance of the WCDMA system is presented and it is evaluated using the MatLab simulation platform, where the theoretical BER was compared for the QPSK and 16-QAM modulation schemes where tables and curves of the bit error rate were obtained. versus signal-to-noise ratio.
