We consider the backward heat equation uxx(x, t) = ut(x, t), ―∞ < x < ∞, 0 ≤ t < T. The solution u(x, t) on the final value t = T is an known function gT(x). This is a typical ill-posed problem, since the solution - if it exists - does not depend continuously on the final data. In this paper, we shall give a Shannon wavelet regularization method and obtain some quite sharp error estimates between the exact solution and the approximate solution defined in the scaling space Vj.
