Abstract
본 발명은 동일채널 입력을 받아 Multipath Fading 이나 Chnnel Noise를 제거하여 동일 채널로 전송하는 중계기이다. EDOCR의 핵심 기술은 Equalizer(등화기)이며, 이 기술로 인해 다른 주파수로 송출하는 중계기에 비해 월등히 주파수 자원을 절약하여 보다많은 방송국들으 허가가 가능하고 주파수 자원을 다른 자원으로 활용 할 수 있다. 그리고 전체 시스템의 Local 신호를 위성 위치 추적 장치(GPS)를 이용하여 전체 망동기를 잡아 주는 것이 특징이며 증폭기의 선형성을 보장해 주기 위하여 DPD(Digital Pre-Distorter)를 사용하 였다.The present invention is a repeater that receives the same channel input and removes the multipath fading or channel noise and transmits the same channel. EDOCR's core technology is the Equalizer, which saves much of the frequency resources compared to repeaters that transmit on other frequencies, allowing more stations to be licensed and using those resources as other resources. In addition, the local signal of the entire system is captured by the GPS, and the DPD (Digital Pre-Distorter) is used to guarantee the linearity of the amplifier.

Description
국간 동기를 위해 GPS(Global Positioning System)를 수용하여 송수신 모듈 및 중계기간 시간지연을 해결 하였다. 그리고 증폭기의 비선형성을 보상하기 위하여 DPD(Digital Pre-Distorter)를 사용하여 시스템의 효율및 크기를 최소화 할 수있다.For synchronization between stations, GPS (Global Positioning System) was adopted to solve the time delay between the transmission and reception module and the relay period. In addition, the digital pre-distorter (DPD) can be used to compensate for the nonlinearity of the amplifier, minimizing the efficiency and size of the system.
본 발명은 ATSC(Advanced Television System Committee)방식의 지상파 DTV를동일 채널 중계를 하기 위한것이다.The present invention is intended for the same channel relay of the Terrestrial DTV of the Advanced Television System Committee (ATSC) system.
동일 채널 방송용 지지탈 중계기응 적용하여 주파수 재배치 시 막대한 금액의 주파수 자원을 절약할 수 있음. It can save huge amount of frequency resources when relocating frequency by applying support derelay relay for co-channel broadcasting.
상기와 같은 목적을 달성하기 위하여 수신 모듈에서 전송된 RF 신호를 기저대역으로 변환하는 모듈과 기저대역으 신호를 RF 신호로 변환하는 송신모듈로 구성 된다. In order to achieve the above object, it consists of a module for converting the RF signal transmitted from the receiving module to the baseband and a transmitting module for converting the baseband signal into an RF signal.
그리고 기저대역에서 채널 노이즈를 제거하여 신호를 재 전송하는 등화기와 증폭기의 선형성을 보상하고 효율을 향상 시킬 수있는 디지탈 증폭기로 구성되어 있다. It consists of an equalizer that retransmits the signal by removing channel noise from the baseband and a digital amplifier that can compensate for the linearity of the amplifier and improve the efficiency.
향후 방송 통신 융합 시대에 적용 가능한 상당수의 주파수 자원을 확보할 수 있으리라 예상 됨.It is expected that a considerable number of frequency resources can be secured in the era of broadcasting and telecommunication convergence.
