I'm wonderning if I could get
some reference material or email on the SNR loss
with respect to Doppler losses and, if possible
its effect w/r to modulation schemes. Mostly interested
in X-to-V band with M-ary FSK, but PSK schemes,
QPSK, CDMA would also be of interest.
would like to know timing delays for typical doppler
compensation rate loops (ie how fast can ompensation
loops track back to the reference signal? How many
cycles are necessary to determine proper compensation?
Is there an upper slew rate that is normally set
for max doppler compensation in terms like (delta
F/F) ? etc.)
