Title: Apparatus and method channel estimation in communication system
Inventor: KWON HYEONG UK
IPC: H04B7/26
Filed: 2000-03-15
Abstract: PURPOSE: An apparatus and a method for estimating channels of a communication system are provided to improve the quality of a receiver through exact channel estimation by estimating channels by using all signals including a pilot signal. CONSTITUTION: A pilot channel correlator(52) takes correlation with a Walsh code of a pilot channel for detecting the transmitted signal. A target channel correlator(53) takes correlation with a Walsh code of the corresponding target channel for detecting the signal transmitted through a target channel. The first and the second filter parts(54,55) perform channel estimation by using additional information bit and the output signal of the pilot channel correlator(52). An adder(59) adds and outputs the output signals of the first and the second filter parts(54,55). A power control demodulator(61) demodulates the output signals of the pilot channel correlator(52) and the second filter part(55). A traffic channel demodulator(64) demodulates the output signals of the adder(59) and the target channel correlator(53). The first combiner(66) combines the outputs of each power control demodulators(61) of a plurality of fingers(65) for outputting additional information bit. The second combiner(68) combines the outputs of each traffic channel demodulator(64) of the plurality of fingers(65) for transmitting to a decoder.

Title: 전면부 개폐식 자동수문의 구성방법
Inventor: HAN SANG KWAN
Filed: 2000-05-30
Abstract: 본 발명은 하천이나 저수지의 여수로(余水路) 또는 관계용수로에 설치하여 저수측(貯水側)의 수위를 항상 일정 범위 내로 유지하기 위한 자동수문에 관한 것으로서, 수위감지센서의 수위감지에 따라 실린더에 의해 자동으로 개폐작동이 이루어지면서도 개방시 저수측에 저장된 물의 배수가 원활하게 이루어지고, 또 수문본체와 근접한 저수측 바닥에 토사나 자갈이 쌓이더라도 개폐작동이 원활하게 이루어지며, 배수를 신속하게 할 수 있음과 함께 특히 홍수시에 돌이나 나무 등이 수문본체에 충돌하여 수문본체가 파손되는 현상을 방지할 수 있는 자동수문을 제공하는 것을 과제로 한다. 
     본 발명의 자동수문은, 수로의 폭방향 양측에 소정의 간격을 두고 축조된 벽체와, 벽체의 하단부에는 기초가 구비되며 기초콘크리트에 구성되는 회동축[9]에 의해 경사지게 장설되는 수문[1]에 의해 수로가 차단되며 수문을 개폐시키기 위한 실린더[7]와 실린더로드[6]가 실런더축[5]과 실린더로드축[4]에 의해 고정된 구조이다. 
     수로를 차단하여 주는 수문[1]의 형상은 격자형태 또는 H빔과 같은 부재에 의해 견고하게 구성되며 수문[1]의 상단부에는 유동축[3]에 의해 이물질유입 방지판[10]이 연결되어 구성되어 있다. 이물질 유입방지판[10]의 종단부에는 다수개의 로라[2]가 구성된 구조이다. 
     수문과 함께 구성되는 실린더의 숫자는 하천의 상류로부터 유입되는 유입수의 힘과 수로를 차단하고자 하는 높이에 따라서 또는 넓이에 따라서 수문에 부착되는 실린더의 숫자가 결정되는 것이기 때문에 중요한 의미가 없는 것이다. 
     때에 따라서는 1한개의 실린더 많으로도 수로를 차단할 수가 있는 것이기 때문이다. 
     차단하고자 하는 수로가 넓거나 높을 때에는 수문에 부착되는 실런더의 숫자를 많이하여 수로 차단판을 구성시킬수가 있는 것이기 때문이다. 
     수문[1]과 함께 구성되는 실린더[7]와 실린더 로드[6]를 보호하기 위하여 보호대를 구성시키는 방법은 다양한 것으로서 다음과 같은 방법이 사용될수 있는 것이다. 
     실린더와 실린더 로드의 수축과 팽창 작용에 의하여 수문이 개폐되면서 필요한 용수의 확보와 배출을 자유자재로 운용할 수가 있는 것으로서 이러한 작용을 할 때에 유입되는 유입수와 함께 섞여서 흘러내려오는 모래자갈들에 의하여 실린더와 실린더 로드가 파손 될 수가 있는 것이다. 
     본 발명에서는 이러한 문제점들은 해결하기 위하여 일정한 형상을 구비한 고무판재를 이용하거나 금속재를 이용하여 실린더와 실린더로드가 작동할때마다 동시에 작동하여 주는 신축성을 가지고 있는 부재를 이용하여 실린더 와 실린더 로드를 보호 하여 주는 보호대를 구비한 형상이다. 
     상류로부터 유입되는 저수측의 수위를 감지하기 위한 수위감지센서(11)그리고 수위감지 센서와 연결되는 압력발생장치가 배관으로 실린더(7)와 연결된 구조로서, 수위감지센서의 수위 감지에 따라 실린더의 로드(6)가 신장 또는 축소되는 것에 의해 수문[1]이 회동축(9)을 중심으로 도복하여 자동 개폐되도록 된 것을 특징으로 한다. 
     본 발명의 수문은 수위감지센서의 수위감지에 의해 전달되는 압력발생장치의 압력에 의해 수문의 개폐작동이 자동으로 이루어지는 것임은 물론, 개방 작동시 수문이 도복하여 개폐하는 것이므로 수문본체와 근접한 저수측 수로의 바닥에 토사나 자갈이 쌓여 있는 상태라 하더라도 개방 작동이 원활하게 이루어 진다. 또한 수문 본체의 상부로 배출하고자 하는 양 만큼 배수가 이루어지는 것이므로 배수 단면적을 극대화하여 신속한 배수를 도모할 수 있고 특히 배수시 수문본체에 돌이나 나무 등이 충돌하여 수문본체가 파손될 우려가 없다.
