This is Narrow band demodulator IP, it performs
demodulation according to DVB-S, legacy DirectTV, DVB-S2 and DVB-S2X specifications.
The input signal from the tuner is A-to-D converted
on 10 bits. The DC offset, amplitude mismatch and
quadrature error are corrected and the AGC signal
level to the tuner is calculated. The carrier
frequency offset is corrected. Then the signal is sub
sampled and Nyquist root filtered. The signal
amplitude is controlled through the second stage
(AGC2) block. The pilots, when present, are used to
help phase lock to the symbol stream. The signal is
equalized, descrambled, and passed to the FEC.
An internal state machine controls the automatic
acquisition of a channel with various entry points,
including warm start (known symbol frequency,
small carrier offset), cold start (known symbol
frequency and large carrier frequency offset), and
blind search (all parameters unknown).
