Abstract

각 사용자에게 할당된 확산부호와 속성에 따라 할당된 확산부호로 확산처리가 행해지며 그 결과의 신호는 송신자측에서 변조된다. 수신자측에서는, 상기 방식으로 변조된 송신신호가 수신확산부호 발생기로부터의 속성관련 확산부호로 역확산 처리를 받고, 결과적인 신호는 수신확산부호 발생기로부터의 사용자 특정적 확산부호로 역확산 처리를 받으며, 역확산 처리를 받은 그들신호는 데이타 복조기에 의해 복조되어, 광대역 서비스에 해당하는 소망신호와 함께 소망정보가 추출된다. 따라서 개별사용자와 개별서비스의 관리를 간략화하고 시스템 설계를 용이화 하는 것이 가능하다.
