The terrestrial digital video broadcasting (DVB-T) of European Standard has adopted the orthogonal frequency division multiplexing (OFDM) modulation technique, that offers a high-rate, high bandwidth-efficient digital transmission and multimedia services over frequency-selective fading channels. However, OFDM is very sensitive to synchronization errors, and the synchronization of OFDM includes symbol timing, carrier frequency offset (CFO) and sampling frequency offset (SFO). The synchronization scheme is mainly based on the correlation of cyclic prefix and the pilot signals.
This thesis has studied the effect of synchronization errors on the system, proposed schemes for each synchronization, and presented a synchronization system for DVB-T receiver. To implement the synchronization system on FPGA hardware, this thesis includes coding the presented synchronization system with Verilog language and verifying the function of modules with ModelSim software and FPGA hardware platform. |
