Abstract
In this thesis, we propose an integrated system architecture, which is based on the concept of OFDM, for DVB-T、DVB-H and ISDB-T systems. The baseband equivalent channel model includes effects of multipath fading channel, Doppler Effect, Carrier Frequency Offset, Sampling Clock Offset and Additive White Gaussian Noise. In the receiver part, because the receiver need to detect the correct system mode、FFT size and Guard-Interval Ratio length in the beginning, so we according to the different sampling rate between systems and delay correlation function to realize the mode detection, and combines algorithms of symbol timing detection, CFO and SCO estimation, compensation, and tracking, 2K-4K-8K FFT processor, phase modification and channel estimation and compensation. In hardware circuit design, this thesis uses output SNR instead of Bit Error Rate as the metric of optimum word length. Finally, we realize the hardware circuit simulation and implementation by Verilog HDL.
