Assume that a picture is multiplied by the noise sin(Ax+By). how can I clear the noise using deconvolution?

The easiest thing to to not use convolution and just divide by the known pattern. Any reason why you're not doing that?
Otherwise you can find the low frequency spikes in the Fourier domain and erase them. See attached demos.

The question in the homework asks us to use deconvolution.
