Abstract

In order to guarantee the multiuser transmission performance of a chirp spread spectrum system, the cross-correlation coefficient (CCC) among multiple users should be carefully considered. In this paper, we propose a chirp rate allocation scheme for reducing the multiple access interference based on the cross-correlation coefficient. The simulation results show that the proposed scheme can improve the multiple access interference performance.

처프 확산 대역 시스템의 다중 사용자 전송을 위해서는 서로 다른 사용자마다 직교성이 보장된 처프율을 할당해야 한다. 본 논문은 다중 접속 간섭을 감소시키기 위해 상호 상관 계수 기반 처프율 할당 기법을 제안하였다. 모의실험 결과, 제안된 기법의 전송 성능이 기존의 기법보다 우수한 것을 확인하였다.
