최근 DS-SSMA 시스템을 위한 새로운 확산 시퀀스 제품군으로 UCHT(Unified Complex Hadamard Transform)가 제안되었습니다. 이 편지에서는 UCHT(Unified Complex Hadamard Transform) 시퀀스의 PAC(주기적 자기상관) 속성이 분석됩니다. 역위상 PAC의 상한은 UCHT 시퀀스의 두 그룹, 즉 HSP-UCHT 및 NHSP-UCHT 시퀀스에 대해 파생됩니다(후자는 잘 알려진 Walsh-Hadamard(WH)의 보다 일반적인 표현입니다. 시퀀스). 두 경계의 비교가 수행됩니다. HSP-UCHT 시퀀스는 역위상 PAC에 대해 하한 상한을 갖는 것으로 나타났습니다. 이는 DS-SSMA 시스템의 다중 경로 효과에 대처할 때 HSP-UCHT 시퀀스를 WH 시퀀스보다 더 효과적으로 만듭니다.

Abstract: The UCHT (Unified Complex Hadamard Transform) has been proposed as a new family of spreading sequences for DS-SSMA systems recently. In this Letter, the periodic autocorrelation (PAC) properties of the Unified Complex Hadamard Transform (UCHT) sequences are analyzed. Upper bounds for the out-of-phase PAC are derived for two groups of the UCHT sequences, namely the HSP-UCHT and the NHSP-UCHT sequences (the later is a more general representation of the well-known Walsh-Hadamard (WH) sequences). A comparison of the two bounds is performed. It turns out that the HSP-UCHT sequences have a lower upper bound for the out-of-phase PAC. This makes the HSP-UCHT sequences more effective than the WH sequences in combating multipath effect for DS-SSMA systems.
