DEVICE FOR ADAPTIVELY SYNCHRONIZING TO RECEIVED PERIODIC SIGNAL AND DIGITAL SIGNAL PROCESSOR FOR ADAPTIVELY SYNCHRONIZING TO RECEIVED SINE CURVE-SHAPED SIGNAL AND DIGITAL SIGNAL PROCESSOR FOR ADAPTIVELY TUNING TO RECEIVED PERIODIC SIGNAL

摘要

PURPOSE: To provide a device for operating adaptive tuning to a received periodic signal. ;CONSTITUTION: In this device 10, preferentially, a digital signal processing technique for the algorithmic generation of a sine curve-shaped output estimation signal (ext. x_n+1) is used, a difference between the output estimation signal and a reception signal (x_n+1) is decided, and an error signal is generated based on the difference between the output estimation signal and the reception signal. At least one coefficient of the algorithmic decision of the output estimation signal is adaptively changed so that an error between the output estimation signal and the reception signal can be reduced.;COPYRIGHT: (C)1995,JPO
