Diseño y simulación de la técnica OFDM para redes inalámbricas móviles sobre Simulink y tarjeta FPGA.

Abstract

This complex examination work consists of the design and simulation of the orthogonal frequency division multiplexing modulation (OFDM) technique for mobile wireless networks such as WiMAX. Chapter 1 briefly describes the introduction of WiMAX and its relationship to OFDM. The background of the research, the definition of the problem, the justification and the objectives of the degree project are also described. In Chapter 2, the theoretical foundations of the WiMAX communication system and the OFDM modulation technique are presented. Finally, in chapter 3, the design and simulation of the proposed work is presented. For the implementation it was necessary to use the software environment (simulation) and hardware (programmable gate matrix, FPGA). At the simulation level, two robust programming environments were used, such as MatLab / Simulink software and Xilinx ISIM software. MatLab / Simulink also uses FPGA libraries. Whereas in the ISIM software the transfer level register (RTL) programming is performed.
