Simulación en MATLAB de los detectores ZF, MMSE e ID para un sistema SEFDM utilizando un canal con desvanecimiento.

Abstract

This degree project presents the simulation of ZF (Zero Forcing), MMSE (Minimun Mean Square Error) and ID (Iterative Detector) detection techniques for the SEFDM (Spectrally Efficient Frequency Division Multiplexing) multicarrier transmission system over a Rayleigh frequency selective fading channel and AWGN (Additive White Gaussian Noise) channel with different transmission parameters which is carried out in MATLAB software in order to determine the performance of the detection algorithms in terms of error rate and simulation times. The simulation results are presented through plots of BER (Bit Error Rate) vs Eb/No (Energy Per-Bit to Noise Power Spectral Density Ratio) and simulation time. The project is divided into four chapters. Chapter 1 presents the theoretical concepts of the project related to a SEFDM system, propagation channel and detection mechanisms, using block diagrams. As well as the parameters used to determine the performance of the procedure. Chapter 2 describes the process necessary to implement the simulation in MATLAB of a SEFDM transmitter and receiver, propagation channel with Rayleigh and AWGN fading, as well as the ZF, MMSE and ID detection mechanisms by means of functions and scripts. Chapter 3 presents and analyzes the results of the simulations for the different configurations and modulations, through BER vs Eb/No plots, as well as bar charts of detection times. Finally, chapter 4 exhibits the conclusions and recommendations of technical project.
