Abstract

본 발명은 CDMA형 무선사설교환 시스템의 채널설정방법에 관한 것이다. 본 발명은 종래의 코드운용방식에 비하여 그 처리절차와 코드운용 방법이 매우 단순하므로 실제 구현에 있어서 매우 편리하다. 따라서, 소규모의 무선사설교환 시스템을구현하는데에 있어서 효과적으로 적용할 수 있다. 또한, 회로구성과 처리 알고리즘이 단순하고 별도의 데이타 채널이 필요하지 않으므로, 휴대기와 기지국의 소형화에 용이하고 시스템 구성 비용을 저하시킬 수 있다.The present invention relates to a channel setting method of a CDMA type wireless private switching system. The present invention is very convenient in actual implementation because the processing procedure and the code operation method is very simple compared to the conventional code operation method. Therefore, the present invention can be effectively applied in implementing a small wireless private exchange system. In addition, since the circuit configuration and processing algorithms are simple and separate data channels are not required, the portable and base stations can be easily miniaturized and the system configuration cost can be reduced.
