I ABSTRACT STUDY OF OFDM PERFORMANCE OVER AWGN CHANNELS by Ender Bolat 999293 Electrical and Electronic Engineering Department Eastern Mediterranean University Supervisor: Asst. Prof. Dr. Erhan A. Ince Keywords : wireless communications, terrestrial digital video broadcasting, OFDM, AWGN, SNR, symbol error rate The next generation wireless communications systems need to be of a higher standard in order to provide the customers with the multitude of high quality services they demand. In recent years, Orthogonal Frequency Division Multiplexing (OFDM) has been successfully used in terrestrial digital video broadcasting and showed it is a strong candidate for the modulation technique of future wireless systems. This project is concerned with how well OFDM performs when transmitted over an Additive White Gaussian Noise (AWGN) channel only. In order to investigate this, a simulation model was created and implemented using MATLAB. The OFDM signal was transmitted over the AWGN channel for various signal-to-noise ratio (SNR) values. To evaluate the performance, for each SNR level, the received signal was demodulated and the received data was compared to the original information. The result of the simulation is shown in a plot of the symbol error rate versus SNR, which provides information about the system’s performance. The plot shows that OFDM performance is good over this type of channel.

II ACKNOWLEDGEMENTS First of all I’m grateful to Allah for giving me strength and wisdom throughout all my life and especially to finish this project. I thank my family for their love, their moral and financial support they had given me. This helped me a lot. I thank my project supervisor Assist. Prof. Dr. Erhan A. Ince for the help he has given me in completing this project. I hope we will see each other again and maybe work together in the future. Last, but not least, I thank all my friends, both here and back home, who have been there for me when I needed them. They are NOT ordered according to their importance to me; it’s just the order they came to my mind; so here are some of them: Umut Beyazitli, Ilyas Haciomeroglu , Imran Javaid, Abdallah. S. Abdallah, Abdisalam Houssein, Issa Housein Djama, Chingiz Abdurrahmanov, Tarlan Bilalov, the romanian group in Cyprus ( Osman Suliman, Behruz Saganai, Deniz Serif, Olgun Memedula, Leila Septar, Enise Sali), my
