Abstract
A new method of spline wavelet self-convolution (SWSC), which is used to re solve the overlapped peaks with noise, is presented in this paper. The reso lution of several kinds of overlapped peaks with noise simulated by compute r has been discussed in details. It is made known that the overlapped peaks with noise can be separated(S/N > 50) directly and the noise is removed at the same time in time domain. Base-line can be separated and the relative errors of peak area and position are <5.0%. The satisfactory results are al so obtained by resolving the capillary electrophoresis (CE) overlapped sign als with noise. (C) 2001 Elsevier Science B.V. All rights reserved.
