and narrowband (20 ms) IQ-vector powers during 1 s intervals. Both values are em-
pirically related by the expression

C/N

[db-Hz] = 41.5 + 1.1· (SNR [db] – 13.0)

which is also used to compute C/N

values prior to frame lock. SNR values obtained

with representative antenna systems range from a minimum of 5 dB to a maximum of
20 dB. This corresponds to C/N

0

values between 33 dB-Hz and 49 dB-Hz, respec-

tively.
