摘要： A tracking apparatus and method are provided which can reduce the effects of multipath interference which occurs when a receiving end of a mobile communication system tracks a received signal. The tracking apparatus includes an interference remover for removing an interference component contained in an early energy signal and a late energy signal which are used for tracking.

摘要： An optical fiber array module is provided. The optical fiber array module includes a light emitting device to emit light having a pre-set convergence angle through a a side surface (having a window or opening) thereof; an optical fiber array including a plurality of optical fibers (each optical fiber being an optical transmission medium); and a concentrator having a first side surface, a second side surface facing the side surface of the light emitting device, and a through-hole extended from the first side surface to the second side surface, wherein the through-hole has a width gradually narrower in a direction from the first side surface to the second side surface, wherein an end portion of the optical fiber array is inserted into the through-hole, thereby enabling concentration of the end portion of the optical fiber array d.
