摘要： A receiver of a mobile station or a base station in radio communications is formed by a correlation unit for generating a delay profile for specifying paths by taking correlations by using replica signals for a received pilot signal, and a path selection unit for comparing a power level of each path in the delay profile with a threshold determined according to an index value regarding a communication state, selecting paths for which a comparison result satisfies a prescribed condition as valid paths, and outputting a selected delay profile formed by the valid paths as a channel estimation value.

摘要： An image of a scanning position on a faceplate on a light receiving region defined by an arrangement of n light receiving elements such that an amount of light received by the light receiving region becomes a peak at a center of the light receiving region in an arranging direction of the light receiving elements and is gradually reduced substantially symmetrically toward both ends thereof in the same direction. Therefore, if there is no defect in the surface of the faceplate, levels of light receiving signals of the light receiving elements arranged substantially symmetrically in position on both sides of the light receiving region with respect to the center thereof as a reference are substantially equal and there is no substantial difference therebetween. When there is a recessed or protruded defect in a scan position of the faceplate surface, the image on the light receiving region is shifted in either direction from the center by light reflected by a side slope portion of the recessed or protruded defect and the difference of the levels of the light receiving signals in symmetrical positions becomes large. The defect is detected when the difference is larger than a predetermined value.

摘要： Inspection with respect to a defect on a surface of a substrate with an inherent or partial wave-like distortion is performed with high accuracy in consideration with the fluctuation caused by the wave-like distortion detected by the defect in excess of the signal level. The substrate is diagonally illuminated while being rotated and moved toward one axial direction to detect the specular reflected light and the scattered light. Based on the detected signal waveform, the state with respect to the inherent or partial wave-like distortion is determined. When the wave-like distortion exists in the substrate, the waveform is divided, and the threshold value is set for the divided regions. The signal higher than the threshold value will be output or displayed as the defect.
