| 摘 要： | p元d型序列是一类和级联GMW序列一样具有理想自相关性能的序列.它原有的迹函数生成方法需要大量非线性运算,并且需要掌握较多的有限域知识,不利于工程人员快速方便的进行序列的软硬件实现.通过对p元d型序列和移位序列的研究,提出了一种快速生成p元d型序列的算法,该算法借助m序列和相应内部序列的移位序列能够快速生成p元d型序列,比以往的生成方法简单易行且易于理解.

| Abstract: | p-ary d-form sequences have optimal correlation properties like cascade GMW sequences.The original method of constructing these sequences needs lots of nonlinear operations.Engineers must master much limited field knowledge and have difficulty in implementing these sequences with software and hardware.By studying p-ary d-form sequences and shift sequences,a new algorithm for accelerating constructing p-ary d-form sequences is presented.Using m sequences and shift sequences of the inner sequences we can get p-ary d-form sequences quickly and this method is easy to understand and implement. |
