무선이동통신 시스템에서 두 수열의 상호상관 함숫값은 통화 품질과 사용자 수를 결정하는데 있어 큰 영향을 끼치고 있다. 본 논문에서는 주기 $2^n-1$ 인 m-수열에 새로운 데시메이션 $d=\frac{2^{m-st-1}}{2^s-1}(2^n+2^{st+s+1}-2^{m+st+1}-1)$ 를 적용하여 또 다른 m-수열을 생성하고 두 수열의 상호상관 함숫값과 그 값들의 발생횟수를 결정한다. An important problem in the transmission performance and efficiency is to find the values and the number of the cross-correlation function between two different maximal sequences. In this paper, we present the new maximal sequences which are obtained by the new decimations $d=\frac{2^{m-st-1}}{2^s-1}(2^n+2^{st+s+1}-2^{m+st+1}-1)$ from some maximal sequences. We will also find the values and the number of occurrences of each value of the cross-correlation function from the proposed decimations.
