4.4.2.26.1 Noise Generator
The Noise Generator, shown in Figure 133, optionally sums AWGN (Additive White Gaussian Noise) with the
received signal to achieve the desired E
b
/N
0
. Since the bit error rate of an ideally modulated signal at any given
E
b
/N
0
is known and should be readily reproducible, the Noise Generator may be used to verify transmitter or
receiver RF integrity. Two parameters are available: Test Noise and Noise Level.
