Patent JP-H0714258-A (JP)
Title: Tracking controller
Inventor: INAI MICHIFUMI
IPC: G11B15/467
Filed: 1993-06-28
Abstract: PURPOSE:To eliminate the necessity of a plurality of times of envelope-level detections performed at respective tracking phase steps by a method wherein curve regression calculation is applied to the tracking phase and the characteristic curve of the envelope-level of reproducing signals. CONSTITUTION:Curve regression calculation is performed in a curve regression calculator 115 by using 256 data pairs (Xi, Yi) (wherein (i) denotes an integer not larger than 256) which are inputted from a data extractor 119. At that time, it is assumed that a tracking phase X and a reproducing signal Y approximately satisfy an equation (I):Y=aX<2>+bX+c. Under this assumption, the coefficients (a), (b) and (c) of the quadratic equation (I) are so determined as to have the equation (I) most closely agree with the characteristics of the actual measured data (Xi, Yi). With this constitution, even if the required time of a tracking operation for a conventional apparatus is short, or if the head width of a rotary head which is used for reproducing is different from the track width of a helical track, an optimum tracking phase can be determined uniquely and with a high accuracy.

Title: Signal system detecting method
Inventor: MUTO HIROYASU
IPC: H04L7/033
Filed: 1989-06-21
Abstract: PURPOSE:To detect a specific signal system even in fast digital transmission by detecting the fact that the change of a sampled phase is always kept constant at every symbol. CONSTITUTION:In an example in which a signal vector obtained by performing synchronization detection on a digital angle modulation wave (MSK wave) capable of performing cycle detection is sampled with a clock synchronized with the symbol, a white circle shows the example of only a direct wave, and a black circle shows the example of a wave on which a delay wave is superimposed, and those examples correspond to a case where all the signal systems are symbols '1'. At such a case, when the signal vector of the direct wave transits in sequence of 11 12 13 14 11 in a counterclockwise direction, the signal vector of a superimposed wave transits in sequence of 15 16 17 18 15 in the counterclockwise direction. When the change of the phase of the signal vector of the direct wave is always equal to that of the phase of the signal vector of the delay wave, the change of the phase of the signal vector of the superimposed wave is always equal. In such a manner, transmission information can be demodulated correctly even in fast digital communication, and the specific signal system can be detected.
