摘要
针对LabVIEW提供的相关分析数字算法计算结果与相关分析的理论结果存在较大不一致的问题,在对相关数字算法进行讨论和对相关数字算法结果进行分析的基础上,提出一种基于循环相关的相关计算结果修正方法,同时讨论了相关数字算法中尾段数据的失真问题并制定了截取方案.该方法可保证计算结果与理论结果一致.仿真实验表明了有效性.
Due to the results of LabVIEW＇s autocorrelation analysis algorithms differ from the theoretical results,a modification of autocorrelation analysis based on cyclic correlation is proposed in this paper.By discussing the method of autocorrelation analysis algorithm and analysis the results,the paper discusses the problem of distortion and makes the solution.Simulation results shows that the method can reduce errors of autocorrelation analysis effectively.
