has a nice overview of the
problem and solutions.
That article is on HD Radio (IBOC, iBiquity, dismal radio, etc) and
not about conventional FM stereo. While the mechanism for generating
the noise that you don't want to hear is similar, the technology,
solutions, and sources of noise are quite different. For example,
there's no mixing required for the excessive occupied bandwidth of
IBOC to ruin your day.
Incidentally, Brian Beezley has written several other articles on HD
Radio and tuners:

See "HD Radio" section at lower right and various equipment reviews at
