摘要
互相关检测算法是信号检测中广泛使用的方法,但是性能受本地载波频偏影响较大。论文利用Chu序列的性质,给出一类信号检测序列的设计方法,可以在大频偏系统下进行信号检测,并具有计算复杂度低的优点。
A widely used method for signal detection is cross‐correlation detection ,but its performance suffers under large frequency offset .In this paper ,a design method for the sequence of signal detection using some properties of Chu‐ se‐quence .The signal detection under large frequency offset is completed through this method ,which can reduce the computa‐tional complexity .
