Abstract
A smoothing apparatus for peak windowing includes an operator for generating a first input signal for smoothing using an input signal for peak windowing and a predetermined clipping threshold level. The apparatus also includes a subtractor for subtracting a feedback signal from the first input signal, and a maximum operator for generating a second input signal. The apparatus also includes a feedback path for generating a feedback signal for a next smoothed input signal by multiplying samples of the second input signal by window coefficients in a first window coefficient combination and a predetermined gain and summing up the multiplication results. The apparatus further includes a convolutional operator for generating a smoothed signal by multiplying samples of the second input signal by window coefficients in a second window coefficient combination for low pass filtering and summing up the multiplication results.
