This design is a DVB-T2 OFDM demodulator, supplied as portable and synthesizable Verilog-2001 IP. The system was designed to be used in conjunction with a standard RF tuner. QAM signal constellations are supported, including QAM16, QAM64 and QAM256 . QPSK, and BPSK also supported. The operation of the demodulator is automated by a master finite state machine.
