Abstract

In this paper, We have proposed an Heterodyne technique to generate millimeter-wave signal. Microwave signals in cellular broadband mobile communication networks and distributed networks can favorably be generated and distributed by optical techniques. In principle, these techniques have already been investigated for optical control of phase- array antennas, characterization of photo-detector and phase locking of millimeter-wave oscillators and now being applied to wireless communications. The generation and transmission of millimeter-wave radio signals by optical means is of interest for future pico-cell broadband mobile communication system, especially for systems operating at frequencies of 300Hz.

본 논문에서는 밀리미터파 대역의 신호 발생을 위한 헤테로다인 방식을 제안하였다. 향후, 무선 이동통신, 광대역 통신망에 사용되어질 밀리미터파 신호는 전기적 요소의 한계로 광학적인 요소에 의해 신호를 생성하는 방법을 연구 중에 있다. 광학적인 요소에 의한 여러 가지의 연구들이 광검출기의 기능, 밀리미터파 대역의 발진기의 개발 등이 이루어지고 있으며, 무선 통신망에 적용하기 위한 소자기술 등이 발전되고 있다. 본 논문에서는 향후 밀리미터파 대역에서 사용되어질 LMDS(Local Multi-point Distribution Service) 등의 시스템에서 광원으로 응용 가능한 방법을 제안하였다.
