I applied this and this is useful in condition when you do not want to
process noise, because it is being multiplied by zero when there is no
signal. But I want that CMA taps remain unchanged when there is no
signal
or just noise. In the above scenario CMA taps change due to presence of
noise, because it tries to equalize noise as well. Thanks for your
comment.

If you can tolerate the stream stopping, use Power Squelch. Otherwise,
time to dive in and follow Tom’s advice from May - disable the CMA taps
update loop when there’s no signal. This whole idea assumes you have a
mostly quiet channel, stationary tx/rx, etc. Interested to hear what you
come up with.
