Underwater acoustic communication. A subcarrier is one
telecommunication signal carrier that is carried on top of
another carrier so that effectively two signals are carried at
the same time. Subcarriers can be used for an entirely dif-
ferent purpose than main carriers. For example, data sub-
carriers are used for data transmissions; pilot subcarriers
are used for channel estimation and synchronization; and,
null subcarriers are used for direct current and guard
banks transmitting no signal. In the IEEE Journal of
Oceanic Engineering (April, 2013), researchers studied
the characteristics of subcarriers for underwater acoustic
communications. Based on an experiment conducted off
the coast of Martha's Vineyard (MA), they estimated that
25% of subcarriers are pilot subcarriers, 10% are null sub-
carriers, and 65% are data subcarriers. Consider a sample
of 50 subcarriers transmitted for underwater acoustic com-
munications.
a. How many of the 50 subcarriers do you expect to be
pilot subcarriers? Null subcarriers? Data subcarriers?
b. How likely is it to observe 10 pilot subcarriers, 10 null
subcarriers, and 30 data subcarriers?
c. If you observe more than 25 pilot subcarriers, what
would you conclude? Explain.
