In the frequency domain shift the template and multiply it by itself
as well as by the noisy signal then multiply these two products
together.

This will result in even more attenuation of any high frequency noise.

The convolution of a convolution may also be deconvolved once or, to
recover the original signal, twice. A lot of folding & splicing may
be necessary.
