and narrowband (20 ms) IQ-vector powers during 1 s intervals. Both values are em-
pirically related by the expression
C/N
0
[db-Hz] = 41.5 + 1.1·(SNR [db] – 13.0)
which is also used to compute C/N
0
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.
