Análisis, simulación e implementación con carácter didáctico del método de detección y corrección de errores convolucional y su decodificación usando el algoritmo de Viterbi

Abstract

In this document, an approach to the convolutional coding technique is made. It is explained in such a way so it can be easily understood. The bases of its decoding are also showed, so it can be later compared with the Viterbi algorithm, which is thoughtfully explained. A MATLAB function is also developed for both coder and decoder using the Viterbi algorithm. The details of the source code are shown together with the theoretical foundations. The most relevant aspects of the convolutional code are included and behavior analysis are made on basis of the simulation results, which allows comparing such data against theoretical concepts. The implementation on FPGA is also made, so it becomes evident the differences between a coder/decoder system created by using a microprocessor against another one created with a dedicated hardware. All of the sub-systems that were developed for both the coder and the decoder are also explained, including those whose function is purely supportive, such as those of the serial communication system. Finally, the conclusions and recommendations of the project are presented.
