description: The object of research of the graduate qualification work is OFDM signals in systems with intensity modulation and direct detection. The purpose of the work is to investigate algorithms for generating OFDM signals for an IMDD system and analyzing their noise immunity under various modeling parameters. In the course of the work a simulation model of information transmission in an optical channel was developed using DCO-OFDM, ACO-OFDM, ADO-OFDM signals in systems with IMDD.Â  An estimate of the optimal offset for DCO-OFDM was made which minimizes the probability of bit error. The influence of the power distribution of the ADO-OFDM signal over its components on the noise immunity was analyzed. The influence of phenomena inherent in fiber-optic communication such as RIN and chromatic dispersion on noise immunity was studied. Based on the analysis, the effectiveness of the investigated methods of generating OFDM signals for systems with intensity modulation and direct detection was evaluated. Open educational resources and information search and analysis programs were used. The Matlab software was applied.
