Abstract

PURPOSE:To suppress a correlation noise, by estimating the correlation of a noise by utilizing the adaptive control of an adaptive type transversal filter, and obtaining noise suppression output. CONSTITUTION:Only a noise component can be obtained by subtracting the output of an identification circuit 3 from the output of an input terminal 1 at a first subtraction circuit 4. The noise component is delayed and set as the input of the adaptive type transversal filter 7, and a tap coefficient is controlled by estimating the correlation of the noise adaptively from the error signal of a second subtraction circuit 5, and its output (noise suppression output) is added on a reception signal, then, it is inputted to the identification circuit 3. In such a way, it is possible to suppress the noise having the correlation adaptively without necessitating knowledge with respective to the noise such as the density distribution of amplitude probability, etc., in advance.
