Abstract
1. 청구범위에 기재된 발명이 속하는 기술분야1. TECHNICAL FIELD OF THE INVENTION
본 발명은 대역확산통신시스템에 관한 것으로서, 특히 파일럿트 채널을 이용한 다중접속 대역확산통신시스템의 송신기 및 수신기에 관한 것이다.The present invention relates to a spread spectrum communication system, and more particularly, to a transmitter and a receiver of a multiple access spread spectrum communication system using a pilot channel.
2. 발명이 해결하고자하는 기술적 과제2. The technical problem to be solved by the invention
본 발명은 하나의 PN코드 발생기를 사용하여 구성을 단순히 하고, 크로스상관특성으로 인한 코드포착특성의 열화를 방지할 수 있는 파일럿트채널을 이용한 다중접속 대역확산통신시스템의 데이타 송, 수신기를 제공함에 있다.The present invention provides a data transmission and receiver of a multi-access spread spectrum communication system using a pilot channel that can simplify the configuration using a single PN code generator and prevent degradation of code acquisition due to cross-correlation. have.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
본 발명의 각각의 출신 트래픽 채널이 각각 직교하는 월시코드를 사용하며, 모두 동일한 PN로드 발생수단의 출력과 곱하고, 확산신호를 결합하는 과정을 제거하여 파일럿트 신호성분이 제어신호 또는 트래픽 데이타 신호 성분에 영향을 받지 않게하고 구성을 간단히 한다.Each originated traffic channel of the present invention uses a Walsh code orthogonal to each other, and multiplies the outputs of the same PN load generating means, and eliminates the process of combining spreading signals so that the pilot signal component is a control signal or a traffic data signal component. Keep it unaffected and simplify your configuration.
4. 발명의 중요한 용도4. Important uses of the invention
본 발명은 다수의 단말기를 가지는 다중접속 대역확산방식의 통신시스템에 유용하게 사용될 수 있다.The present invention can be usefully used in a multi-access spread spectrum communication system having a plurality of terminals.
