Abstract: A receiver of a radio frequency signal having a pseudo-random noise (PRN) code, and techniques of processing such a signal that are especially adapted for ranging applications. A signal corresponding to the PRN code is locally generated and used for decoding the received signal in a manner to reduce ranging errors that can result when multipath (delayed) versions of the radio frequency signal are also present. A significant application of the receiver and signal processing techniques of the present invention is in a Global Positioning System (GPS), wherein a number of such signals from several satellites are simultaneously received and processed in order to obtain information of the position, movement, or the like, of the receiver. A delay locked loop (DLL) correlator, provided in each of the receiver's multiple processing channels, locks onto a line of sight signal from one of the satellites with the effect of any multipath signal(s) being significantly reduced.

Abstract: PURPOSE: A method for selecting an optimum local frequency of a receiver is provided to implement a phase locked loop(PLL) frequency synthesizer for generating a first intermediate frequency(IF) in a signal received through an antenna, so as to fix a third IF as an IF corresponding to a symbol rate and to receive messages through three-time IF detections having characteristics in which a third local frequency and a second IF frequency are decided. CONSTITUTION: A phase locked loop(PLL) frequency synthesizer demultiplies a regular frequency generated from an optional reference frequency generator with a first variable, and generates a reference frequency. The PLL frequency synthesizer demultiplies a local frequency generated from a local frequency generator with a second variable, and generates a comparison frequency. The local frequency generator generates a first local frequency to detect a first IF. The PLL frequency synthesizer compares the reference frequency with the comparison frequency to decide whether the comparing value is within a threshold range. If so, the PLL frequency synthesizer determines the first/the second variables as design standard performance evaluation corporations(SPECs). If the comparing value is not within the threshold value, the PLL frequency synthesizer performs fine adjustments for the first/the second variables and returns to the step of demultiplying the regular frequency.

Abstract: 무한의 에너지원으로서 환경을 오염시키지 않으면서 어느 지역이나 존재하는 풍력은 매우 유용한 에너지원이다. 한편, 바람이 일정한 속도로 유지되지 않고 또한 공기의 밀도가 낮기 때문에 바람의 힘을 동력으로 변환하여 실용적으로 이용하는 것은 쉬운일이 아니다. 현재까지 풍력을 이용하여 전기를 얻는 실용적인 방법은 수평식 풍차형과 수직형 다리우스형으로 대별되고 있다. 이러한 수평형과 수직형은 비행기가 날 수 있는 원리인 양력을 이용하고 있다. 
     본 발명은 바람을 이용하여 동력을 얻을수 있는 새로운 방법에 대한 것으로서 항력을 이용한 것이다. 
     수평식은 효율이 높은 반면 바람의 방향에 따라 기구장치 전체가 회전을 하여야 되며 강한 바람에 약한 단점이 있으며 수직형은 반대로 효율은 낮으나 바람의 방향에 무관하게 작동이 가능하며 강한 바람에 대하여 보다 견고하다.
