摘要: |
在非正交跳频扩展频谱多址通信系统中用作跳频图样的 pk 进制序列族要求具有小的汉明互相关。文[l]中得到了给定长度和字母表大小的序列的异相自相关及互相关的下限,并构造了具有最佳汉明相关性能的序列族。本文中提出一种更一般的构造方法,文[l]的构造是它 的一个特例。构造出的序列族具有最佳汉明相关性能,并且可部分解决Hop-and-Stay问题。 |

Families of Frequency-Hopping Sequences with Optimal Hamming Correlation Properties |
(2.National University of Defense Technology)

Abstract: |
Families of pk-ary sequences with small Hamming crosscorrelation are required for hopping patterns in asynchronous frequency-hopping spread-spectrum multiple-access communication systems. Lower bounds on the out-of-phase auto correlation and on the crosscorrelation of sequences of given length and alphabet size are derived in [l],and a method of constructing families of sequences that uniformly realize these bounds is presented as well. In this paper,a commonest method of constructing families of frequency-hopping sequences with optimal Hamming correlation properties is presented,taking the method in [1] as its special case. By driving the frequency synthesizer from k inconsecutive stages Tather than from k consecutive stages,we can partially solve the Hop-and-Stay problem existing in [1]. |
