الملخص EN

In many applications, observed signals are contaminated by both random noise and blur.

This paper proposes a blind deconvolution procedure for estimating a regression function with possible jumps preserved, by removing both noise and blur when recovering the signals.

Our procedure is based on three local linear kernel estimates of the regression function, constructed from observations in a left-side, a right-side, and a two-side neighborhood of a given point, respectively.

The estimated function at the given point is then defined by one of the three estimates with the smallest weighted residual sum of squares.

To better remove the noise and blur, this estimate can also be updated iteratively.

Performance of this procedure is investigated by both simulation and real data examples, from which it can be seen that our procedure performs well in various cases.
