Title: The noise-eliminator and the designing method of wavelet transformation
Inventor: LEE UNG JAE
IPC: H04N5/21
Filed: 2001-01-18
Abstract: PURPOSE: A noise remover is provided to mount a wavelet transform filter by a pre-filter on a front end of a signal input unit, thereby improving an SNR(Signal to Noise Ratio) of a device using an RLS algorithm as improving a converging speed. CONSTITUTION: A wavelet transform filter(10) is mounted on a front end of an input unit(1). The wavelet transform filter reduces inherent value distributions of an autocorrelation matrix for an inputted noise source of the input unit. When an SE(Signal Estimate) outputted to an output unit(4) is fed back through an adder(3), an adaptive filter(2) minimizes noises of the SE according to the inherent value distributions of the autocorrelation matrix reduced by the wavelet transform filter. An optimum signal is obtained as obtaining an optimum noise estimate value for a polluted signal inputted through the input unit.
