Suppression of interference for DVB-T2 signals

This research project focuses on interferences encountered by Digital Video Broadcasting – Second Generation Terrestrial (DVB-T2) during broadcast transmission. The structure of DVB-T2 signal is learnt through the review of DVB-T2 transmitter model. Several types of interferences, including AWGN, channel fading, co-channel interference and jamming effect are incorporated into the system. Simulation is done on Common Simulation Platform (MATLAB model) developed by the DVB Consortium. Bit-error-rate (BER) graphs are generated to evaluate the overall performance of the system under different levels of signal-to-interference ratio (SIR) and signal-to-noise ratio (SNR). Combinations of multiple interferences onto the system are also implemented. Modifications to the DVB-T2 system (mainly on receiver) such as filtering, are then applied to investigate the feasibility to suppress the effect of interference for improvement in the BER.Bachelor of Engineering (Electrical and Electronic Engineering
