Abstract
Official abstract text for this publication.
A semiconductor device contains a narrow band noise detector section to detect narrow band noise in an input signal that is input by way of a power line. The semiconductor device further includes a reference signal generator section to generate a second reference signal whose amplitude value which corresponds to the narrow band noise frequency of a pre-established first reference signal is reduced, and a correlation calculation section to calculate the correlation value between the input signal and the second reference signal utilized in the frame synchronization processing of the input signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A receiver configured to receive an input signal through power lines, comprising: a narrow band noise detector configured to detect narrow band noise frequency in an input signal; a reference signal generator configured to generate a second reference signal whose amplitude value corresponding to the narrow band noise frequency of a first reference signal has been reduced, a correlation calculator configured to calculate a correlating value between the in…
