초록

본 논문에서는 비주기 자기상관 특성의 중요한 지표가 되는 merit factor의 관점에서 가장 우수한 비주기 자기상관 특성을 갖는 새로운 다중 위상 부호열(polyphase sequence)을 제안한다. 또한, 정수 환(integer residue ring)에서 LFSR(Linear Feedback Shift Register)을 이용한 일반적인 다중 위상 부호열 생성기를 제안하고 제안된 생성기에 기반한 다중 위상 부호열의 선형 복잡도를 분석한다.

In this paper, we propose the new polyphase sequence with the best nonperiodic autocorrelation property in the viewpoint of the merit factors, which are important criteria for a nonperiodic autocorrelation property. We propose the general implementation of a polyphase sequence generator over an integer residue ring by using a linear feedback shift register(LFSR), in addition, we analyze the linear complexities of polyphase sequences based on the proposed implementation method.
