The invention relates to a method for performing an acquisition to a code- modulated spread spectrum signal. The method comprises receiving the transmitted signal, sampling the received signal to form samples, forming at least one reference code corresponding to a code used in the modulation, forming a non-coherent search matrix on the basis of said samples. Said non-coherent search matrix comprising elements in at least a first and a second dimension. The first dimension of said non- coherent search matrix represent the same frequency deviation but different code phases of the received signal, and the second dimension of said non-coherent search matrix represent the same code phase but different frequency deviations of the received signal. Each element is addressable in the first dimension by a first index and in the second dimension by a second index. The method further comprises determining a frequency shift of the transmitted signal and a code phase of the code used in the modulation on the basis of values of elements of said non-coherent search matrix. Said determining comprises defining at least one statistical parameter for at least one line of elements of said non-coherent search matrix in the first dimension on the basis of values of each element of said at least one line of elements, defining a reference value on the basis of a value of an element of said line of elements and said at least one statistical parameter, and examining the reference value to determine whether said element of said line of elements corresponds to the frequency deviation and the code phase of the received signal. The frequency deviation and the code phase of the received signal are determined on the basis of the indices of such element corresponding to the frequency deviation and the code phase of the received signal. The invention also relates to a receiver, a module, a system and a computer program product.

　炭素含有率取得装置（１）では、所定のパラメータ群の値と、炭素含有率とを関連付ける参照情報が予め生成されて記憶される。ガラス基板９上に形成されたＳｉＣ膜に対して、分光エリプソメータ（３）にて測定を行うことにより測定スペクトルが取得され、コンピュータ（６）において当該測定スペクトルから当該パラメータ群の値が求められる。そして、パラメータ群の値および参照情報に基づいて、ＳｉＣ膜の炭素含有率の値が精度良く求められる。

An OTDR device and method for characterizing one or more events in an optical fiber link are provided. A plurality of light acquisitions is performed. For each light acquisition, test light pulses are propagated in the optical fiber link and the corresponding return light signals from the optical fiber link are detected. The light acquisitions are performed under different acquisition conditions, for example using different pulsewidths or wavelengths. Parameters characterizing the event are derived using the detected return signal from at least two of the plurality of light acquisitions.

The present invention is related to a target acquisition system (1) and method (100) that enables the determination of the locations and distances of targets. The target acquisition system (1) according to the invention comprises; at least a imaging unit (2) which enables to capture and thus to display the visible and/or infrared light waves reflected from objects within an environment; at least an informing unit (3) that enables the transmitting of images sensed from a imaging unit as visible and/or audio images and enables to enter commands requested by the user; and at least a controlling unit (4) which enables the processing of images transmitted by the imaging unit (2) in accordance with the commands given by the user and enables to change the position of the Host (K) in order to obtain necessary data.
