Title:
FREQUENCY ESTIMATION IMMUNE TO FM CLICK
Document Type and Number:
Japanese Patent JP2012044656
Kind Code:
A
Abstract:
To provide an apparatus for reducing audio clicks in frequency modulated radio system.
The apparatus for reducing audio clicks in frequency modulated radio system includes a receiver for receiving a frequency modulated (FM) signal, and a processor for demodulating the received signal and estimating a frequency error. The processor determines phase variations of the received FM signal by comparing a phase of a first signal sample to a phase of a second signal sample, in which the first signal sample and the second signal sample are separated in time by two samples or more.
