---------------------------------------------------------
I have a signal currupted by white additive Gausian noise.
y(t) = x(t) + n(t)  ; where n(t) is the additive Gaussian noise
and x(t) is the desired signal. x(t) is not a stochastic signal
but I know its characteristics like it is smooth everywhere
except at the edges. What is the best method to filter out the
noise from the observed signal y(t) to recover x(t)? I would
like to preserve the edges in the signal x(t) which are of utmost
importance to me. Any pointers to literature appreciated.
Thanks
