Abstract
This paper presents an integrated receiver to support multimode broadcasting standards such as DVB-T2, DVB-C2, and DVB-S2 in a single platform. The integrated receiver consists of a tuner block, a receiver engine, a frame processor, and an A/V decoder. The receiver engine includes a channel decoding engine and a demodulation engine to perform OFDM and APSK demodulations. The frame processor performs deinterleaving and BB frame decoding functions. The demodulator engine and the frame processor are implemented in two FPGA devices and DSP-based embedded software, respectively. To verify the functionality of the integrated receiver, it is tested in the laboratory. Commercial PC-based modulators are used to generate the DVB-T2, DVB-C2, and DVB-S2 modulated signals. The integrated receiver was tested under various operation modes as specified in the standards such as DVB-T2, DVB-C2, and DVB-S2 and showed successful operation in all the scenarios tested.
