QS-FHMA(quasi-synchronous FH multiple-access) 시스템에서 NHZ-FHS(no-hit-zone frequency-hopping sequence)는 간섭 없는 FHMA 성능을 제공할 수 있습니다. 그러나 NHZ(no-hit-zone) 외부에서는 기존 NHZ-FHZ의 해밍 상관 관계가 너무 커서 성능이 좋지 않을 수 있습니다. 그리고 고속 모바일 환경에서는 도플러 편이 현상이 나타나게 됩니다. FHMA의 성능을 보장하기 위해서는 전송 지연과 주파수 오프셋이 존재하는 NHZ-FHS에 대한 연구가 필요하다. 이 논문에서는 NHZ-FHS의 NHZ 외부에서 최대 시간-주파수 XNUMX차원 해밍 상관관계에 대한 하한을 도출합니다. Zeng-Zhou-Liu-Liu 경계는 주파수 이동에 대한 새로운 경계가 XNUMX인 특정 상황입니다.

Abstract: In quasi-synchronous FH multiple-access (QS-FHMA) systems, no-hit-zone frequency-hopping sequences (NHZ-FHSs) can offer interference-free FHMA performance. But, outside the no-hit-zone (NHZ), the Hamming correlation of traditional NHZ-FHZs maybe so large that the performance becomes not good. And in high-speed mobile environment, Doppler shift phenomenon will appear. In order to ensure the performance of FHMA, it is necessary to study the NHZ-FHSs in the presence of transmission delay and frequency offset. In this paper, We derive a lower bound on the maximum time-frequency two-dimensional Hamming correlation outside of the NHZ of NHZ-FHSs. The Zeng-Zhou-Liu-Liu bound is a particular situation of the new bound for frequency shift is zero.
