Abstract
본 발명은 주파수도약 송신시스템에 관한 것으로, 주파수 안정기간에도 데이타를 송신하고자 하는 것을 목적으로 한다. 본 발명의 구성은 주파수도약 통신시스템에 있어서, 상기 소정기간을 주기로 토클링동작되는 선택신호와 상기 선택신호의 서로 다른 상태에서 상기 선택신호의 각 엣지들로부터 주파수 안정기간 앞서서 각각 출력인에이블되는 제1주파수제어신호 및 제2주파수제어신호를 발생하는 제어부와; 송신하고자 하는 데이타를 입력한 후 소정 알고리즘에 따라 이를 신호처리하여 출력하는 통신데이타 처리부와; 상기 제1주파수제어신호에 따라 그 주파수가 변환되는 제1반송파신호를 출력하는 제1주파수합성기와; 상기 제2주파수제어신호에 따라 그 주파수가 변환되는 제2반송파신호를 출력하는 제2주파수합성기와; 상기 선택신호에 따라 상기 제1반송파신호 및 제2반송파신호중 그 하나를 선택하여 송신 반송파신호로 출력하는 스위칭수단; 및 상기 송신 반송파신호를 이용하여 상기 통신데이타 처리부의 출력을 변조하여 송신신호를 출력하는 변조부를 구비하는 것을 특징으로 하며, 기밀유지가 요구되는 통신시스템의 실시간통신이 가능하게 되는 잇점이 있다.The present invention relates to a frequency hopping transmission system, which aims to transmit data even during a frequency stabilization period. The present invention provides a frequency hopping communication system, comprising: output enable prior to a frequency stabilization period from respective edges of the selection signal in a different state of the selection signal and the selection signal toggling at a predetermined period; A control unit for generating a first frequency control signal and a second frequency control signal; A communication data processing unit which inputs data to be transmitted and then processes and outputs the signal according to a predetermined algorithm; A first frequency synthesizer for outputting a first carrier signal whose frequency is converted according to the first frequency control signal; A second frequency synthesizer for outputting a second carrier signal whose frequency is converted according to the second frequency control signal; Switching means for selecting one of the first carrier signal and the second carrier signal according to the selection signal and outputting the selected carrier signal as a transmission carrier signal; And a modulator for modulating an output of the communication data processor by using the transmission carrier signal and outputting a transmission signal, which enables real-time communication of a communication system requiring confidentiality.
