Abstract

본 발명은 무전기를 주파수 도약방식으로 운용할 때 다수의 무선망인 무작위 주파수 도약 무선통신으로 인하여 발생되는 상호 무선간섭을 없애기 위한 주파수 도약 무전기의 직교통신방법에 관한 것으로, 도약 방식으로 운용 하는 다수의 무선통신망이 서로 주파수 간섭을 회피하면서 직교도약방식의 무선통신이 이루어지지 않으면 혼신 및 인접채널간섭으로 인하여 전송품질이 급격히 저하되고, 분산된 무전시간 동기유지 및 직교도약패턴 발생의 어려움으로 주파수 충돌을 피하기가 매우 어려웠다. 무전기가 넓은 지역에 분산되어 운용될 경우 직접 통화하지 않는 무전기 사이의 시간동기를 맞추어 모든 무전기가 일제히 시간동기를 유지하면서 도약패턴도 직교관계를 이루어야 직교 통신망 상호 직교도약이 유지되는데, 분산된 다수의 무전기가 특정 무전기에 의존하지 않고 무선망내에서 상대적으로 상대적으로 일제히 시간동기를 맞추고 서로 다른 무전기 사이에 직교 도약패턴을 이루도록 하여 주파수 도약시에도 통신망 상호간에 간섭이 없는 직교 무선 통신망을 유지하도록 한 것이다.The present invention relates to an orthogonal communication method of a frequency hopping radio for eliminating mutual radio interference caused by a random frequency hopping radio communication that is a plurality of radio networks when the radio is operated in a frequency hopping method. If the communication network avoids the frequency interference with each other and the orthogonal leap wireless communication is not performed, the transmission quality is drastically reduced due to interference and adjacent channel interference, and the frequency collision is prevented due to the difficulty of maintaining the distributed non-time synchronization and the orthogonal leaping pattern Was very difficult. If the radios are distributed and operated in a large area, all radios must maintain time synchronization and orthogonality in a leap pattern in order to maintain time synchronization between radios that do not talk directly to each other. In order to maintain the orthogonal wireless communication network without interfering with each other even in frequency hopping, the radio should be time-locked relatively simultaneously in the wireless network without forming a radio, and orthogonal hopping pattern between different radios.
