emergency solution: AM

tomorrow it looks like the best thing to start with is gain control,
to find an optimal feedback coefficient for the PLL. once this works i
can try to find a bitrate that works with the phase error still
happening. then i could hand it over and try to fix the
sync/transition error.

normalization:
  * agc (division + filtering)
  * arctangent

previous conclusion about cordic artangent was that it's hard to do
without a barrel shifter.. i can probably unroll most of this by using
the multiplier and double buffering.

good thing is that this can be used for AM also, without the need for
quadratics.

EDIT:
actually, is should really just do AM by measuring the power. the
previous error (large carrier mismatch) is solved.
