use an modified baseband delay demodulator
...
we are working at sampling rate, so we can use a faster approximation and avoid trigonometric functions altogether.
we still have to normalize the output though.

be more picky about sync pulse position
...
ignore early sync pulses 5 times, then reset.
should be more robust against spurious sync pulses caused by noise or crosstalk
