Abstract: PURPOSE: A method and an apparatus for estimating the dispersion of amplitude probability distribution(APD) model are provided to characterize APD with respect to noises of an electronic device and to acquire bit error rate. CONSTITUTION: An APD curve calculating part(100) calculates an APD curve with respect to the APD model of noises of an electronic device. A linearity decision part(102) verifies the slope linearity of the calculated APD curve. Based on the decision result, a distribution processing part(104) selectively executes an identical distribution process or a different distribution process. If the slope of the calculated APD curve is linear, the identical distribution process is executed. If the slope of the calculated APD curve is non-linear, the different distribution process is executed.

A conversion unit(400) changes the I digital signal of the I filter and an average of the mean value calculation part. A determination unit(500) selects a phase corresponding to a transmission bit based on a predetermined determination reference for a conversion result of the conversion unit.
