Dear all,
although I agree that in the SPECIAL case when the CORDIC
frequency is set to 0 it is meaningful to assume a known
phase (set to 0 at power up or otherwise set externally to 0),
I think it is a bad engineering practice to design receivers that assume
a known phase (ie, a coherent operation) when the CORDIC frequency is
NON-ZERO. I wonder if you share this reservation with me.

Even if you set the frequency to 0, there is a "random" initial phase
that is unknown, and thus you cannot separate the two channels.
The initial phase is always 0 at power up. If you never set the
frequency to something other than 0, it will always stay that way. Its
a simple change to make the phase go back to zero. Patches welcome...
