The OCDM system model
 Sekanina, Tomáš ; Miloš, Jiří (referee) ; Maršálek, Roman (advisor)
Master thesis The OCDM System Model is focused on problematics of multi carrier modulation techniques and in detail analyses the OCDM system. The first part of the work contains theoretical and mathematical description of digital communication system in general. The next part focuses on OCDM system and Fresnel transform, whose discrete form is kernel of the system. Digital model of the OCDM system is realized in programming language MATLAB. In the digital model is performed simulation of information from transmitter to receiver in AWGN and fading channel. The results are evaluated from the viewpoint of the system resilience against errors and achievable system throughput. The end of the master thesis is dedicated to mutual compatibility and comparison between OCDM and OFDM system.

The OCDM System Model
 Sekanina, Tomáš
This paper focuses on the multi-carrier modulation technique called Orthogonal Chirp DivisionMultiplex (OCDM). The first part of the paper contains theoretical and mathematical descriptionof the OCDM system in general. Then digital model of the OCDM modulator and demodulatoris realized in programming language MATLAB. Realization of the model represents two possiblemathematical implementations of the Fresnel transform, whose discrete form is kernel of the system.In the digital model is performed simulation of information from transmitter to receiver in AWGNchannel. Results are evaluated from the viewpoint of the system resilience against errors.
