Title: Carrier frequency synchronization method for orthogonal frequency division multiplex transmission system and synchronization device
Inventor: AHN MYONG-KYUN
IPC: H04L7/00
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To correct a carrier frequency residual deviation in such a way that a rough correction mode where an integer part of the carrier frequency residual deviation is compensated and the fine correction mode where a prime part of the carrier frequency residual deviation is compensated are interlocked at a prescribed time interval by matching frequency synchronization in a satisfactory way, even when the carrier frequency residual deviation exceeds one sub-channel carrier. SOLUTION: After deciding the correction of an integer part and a prime part of a received carrier frequency residual deviation, in the case of correcting the integer part, a hold value detection section 104 receives a carrier to calculate the signal strength, accumulates the calculated signal strength and a strength of a preceding signal delayed by one symbol for prescribed symbols, and counts the accumulated signal strength till the count reaches a setting count to correct the integer part of the received carrier frequency residual deviation.  Furthermore, in the case of correcting the prime part, a residual deviation detection section 105 receives the carrier to extract a pilot, calculates a phase difference between the extracted pilot and a preceding pilot delayed by one symbol and adjusts the gain of the calculated phase difference, so as to correct the prime part of the received carrier frequency residual deviation within a prescribed frequency.

Abstract: PURPOSE:To exponentiate simultaneously while observing a diffraction pattern by using a concentric circle group in which a reference beam incident position is an origin as a scale at an infinitesimal interval of a predetermined value or less. CONSTITUTION:A fluorescent plate 14 is so disposed in a bottom of a mirror 10 as to be perpendicular to a reference beam B, i.e., a zero-order beam, and observed by observation binoculars 20 through a glass window 12 provided at the side of the mirror 10. A circle interval of a concentric circle group displayed together with lines for representing azimuth angles as a scale on the plate 14 is set to 500mum or less, and its center is used as an incident position of the beam B. A sample crystal is disposed several hundreds of mm above the plate 14 on the beam B, and emitted with an electron beam. An zero-order beam which is not diffracted is linearly transmitted through the crystal, and a fluorescent spot is generated at the center of the group of the scale. The diffracted electron beam generates a diffraction pattern on the plate 14 as a pattern of the spot. The pattern is superposed with the scale, and observed thereby to accurately measure it and simultaneously exponentiate it.

And the cap 30 is only put on a standing part 21 and in the case of inspection, it is merely required to lift the cap to slightly, laterally shift it, and hence inspection can be easily conducted even if the space on the rear side of the ceiling is narrow. Further since the lighting fixture 30 is attached to the cap 30, a predetermined distance can be provided from a louver 50 and hence light is properly dispersed in the room.  As a result, the appearance of the ceiling can be improved and construction can be easily performed at low cost.
