摘要
该文提出基于伪随机序列构造高斯整数序列的方法。基于长度为1p^m-的p元伪随机序列,构造得到长度为1p^m-的高斯整数序列,其阶数为p-1。该类高斯整数序列具有几乎完备的自相关性能,其异相自相关函数值仅存在p-2个非零值。并且该类高斯整数序列具有良好的平衡性,在无线通信与雷达系统中都有广泛的应用前景。
A construction of Gaussian integer sequences based on pseudo-random sequences. Gaussian integer sequences with period pm- 1 whose degree p- 1 are constructed from p-ary pseudo-random sequences with period pm- 1. The presented sequences are nearly perfect Gaussian integer sequences with p- 2 non-zero out-of-phase autocorrelation values. Moreover, these Gaussian integer sequences have balance property, as a result, they will be widely used in wireless communication and radar systems.
