Abstract:
A method and apparatus for detecting signal quality, and a computer readable recording medium having embodied thereon a program to execute the method. In the method for detecting the quality of an input signal, an estimated signal is calculated from an input signal by using a predetermined filter coefficient, then the filter coefficient is updated to minimize a difference between the estimated signal and the input signal, and based on the updated filter coefficient, the quality of the input signal is calculated.
