本文介绍了一种新型伪随机序列-相控序列
相控序列具有线性复杂度很大
相关性好
序列平衡的优点.本文提出了对相控序列的改进
使用级连GMW序列代替原始定义中生成相控序列所需的GMW序列
并证明了这种改进的可行性.改进后的相控序列的线性复杂度进一步增大
族数增多但相关性和平衡性不变.
A new pseudo-random sequence-Phase Controlled(PC) sequence was introduced.The PC sequences have many good properties
i.e.very large linear span
good period cross/autocorrelation functions
and all sequences are balanced.Also we propose the method
by replacing the GMW sequence required in constructing PC sequence with the cascaded GMW sequences
thus can improve the properties of the PC sequence.The availability of this method is verified.The improved PC sequences have larger linear span than before
with the same properties of period cross/autocorrelation functions and balance as before.
