Abstract

In this paper, using the binary (N,M,L,1) low correlation zone(LCZ) sequence set with specific property, we propose the construction method of a quaternary LCZ sequence set with parameters (2N,2M,L,2). The binary LCZ sequence using this method must have period $N{\equiv}3$ mod 4, balance property, and specific correlation property. The proposed method is modified from the construction method of binary LCZ sequence set by using binary LCZ sequence with specific condition proposed by Kim, Jang, No, and Chung[4].

본 논문에서는 매개 변수가 (N,M,L,1)인 특정 성질을 가진 이진 낮은 상관 구역 수열균(LCZ sequence)를 이용하여 매개 변수가 (2N,2M,L,2)인 4진 낮은 상관 수열군을 생성하는 방법을 제시한다. 본 논문에서 이용하는 이진 낮은 상관 수열군은 balance property를 가지고 있어야 하며, 주기 N이 $N{\equiv}3$ mod 4이어야 하고, 특정한 상관 특성을 가져야 한다. 새로 제안된 생성법은 특정 성질을 가진 이진 낮은 상관 수열군을 이용하여 이진 낮은 상관 수열군을 생성한 Kim, Jang, No, and Chung의 생성법을 응용한 것이다.
