Abstract

본 발명은 분산 송수신 시스템 및 확장 무선 네트워크에 관한 것이다. 본 발명의 일 실시 예에 따른 분산 송수신 시스템은 분산 송신 시스템, 분산 수신 시스템 및 분산 중계 시스템을 포함한다. 발신 무전기의 발신 신호는 분산 송신 시스템을 거쳐 복수 개로 나누어지고, 동료 무전기를 통해 중계되어 통달 거리 밖에 있는 다른 네트워크에 분산되어 전송될 수 있다. 다른 네트워크에 위치한 목적 무전기는 분산 수신 시스템을 거쳐 동료 무전기의 중계 도움을 받아 발신 무전기의 원래 신호를 복원해 낼 수 있다. 중계를 도와주는 동료 무전기가 원 발신 신호의 일부분만을 선별하여 증폭하므로 신호 강도가 강해질 수 있다. 이에 따라, 중계를 도와주는 동료 무전기의 출력을 합치면 동료 무전기의 합은 고출력 무전기 역할을 하여 원래 통달 거리 능력보다 더 큰 능력을 갖는다. 분산 송신 시스템과 분산 수신 시스템을 하나의 네트워크 내에서 수행하게 되면 분산 중계 시스템이 구축된다. 분산 중계 시스템은 다른 네트워크에서 도달한 신호가 또 다른 네트워크로 전송되도록 중계하여, 결과적으로 무선 네트워크 영역을 확장시킨다.
