TC-19-03 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering in Telecommunications Thesis (M. Eng.) - Asian Institute of Technology, 2019 Since the High-Speed Train (HST) communications are suffering from the huge Doppler shift, an efficient coding scheme method is proposed in this thesis. The proposed method mainly concerns about the mitigation of Doppler shift in Orthogonal Frequency Division Multiplexing (OFDM) based systems, especially for the case of employing mmWave with very high mobility. The proposed method can be used for both downlink and uplink of the system and it is quite robust to the time-varying mobility. Simulation results show that by using the proposed method, it gives better performance with varying velocity and modulation techniques according to 5G requirements. 5G mobile communication systems Coding theory Orthogonal frequency division multiplexing Attaphongse Taparugssanagorn, Chairperson Poompat Saengudomlert, Examination Committee Teerapat Sanguankotchakorn, Examination Committee AIT Fellowship, Scholarship Donor Asian Institute of Technology.
