给出一种利用约束条件和特征相位求取平衡Gold序列的方法,能够获取一族Gold序列中的所有平衡序列。该方法由前后两部分组成,在前部分中,寄存器级数n为奇数时可获得族中的全部平衡序列;n为偶数时可获得族中约占50%的平衡序列。在后部分中,可获得n为偶数时族中剩余约占25%的平衡序列。该方法以MATLAB为仿真平台进行编程实现,结果表明所给出的方法及各相关结论的有效性和正确性。
A method of using the constraints and feature phases to find the equilibrium Gold sequence is given, which can obtain all the equilibrium sequences in a family of Gold sequences. The method consists of two parts. In the former part, when the register sequence number n is odd, all equilibrium sequences in the family can be obtained. When n is an even number, about 50% of the equilibrium sequences in the family can be obtained. In the latter part, it is possible to obtain a balance sequence with about 25% remaining in the even-numbered n. The method is programmed by using MATLAB as the simulation platform. The results show the validity and correctness of the proposed method and the related conclusions.
