Simulace modulace a demodulace digitálních signálů pomocí programu GNU Octave

Abstract

Bachelor's thesis deals with simulation of modulation and demodulation of digital signal with use of GNU Octave software. Concretely it's about digital modulation for ASK, FKS, PSK and QAM. Included in theoretical exposition is explanation of modulation and demodulation processes, main terms and dispensation of basic signals and modulations. Basic properties, process of installation, needed configuration, advantages and disadvantages of program GNU Octave are mentioned. Realization of simulation itself is made of program code and graphic output. Functionality of used commands and personal algorithms is explained. Processing of noise like AWGN is within the simulation. Closer explanation of drawing functions is part of making a tutorials for school lessons, where the automatization of simulation is done. Overall program code is placed on the DVD for free spreading and use on the GNU Octave software.
