摘要
数字信号处理不仅在电子通信领域应用广泛,在数学领域也是一种重要的工具。本研究介绍了插值算法原理,随后对各种窗函数进行分析,并提出在数字信号处理中加Blackman窗插值FFT算法最优越的猜想,最后通过MATLAB软件仿真,分析仿真数据,得出该猜想是正确的结论。
Digital signal processing not only has wide applications in the field of electronic communications, but also is a kind of important tool in mathematics. The principle of interpolation algorithm was introduced, then all sorts of window function were ana- lyzed,and put forwards conjecture that adding Blackman window interpolation FFT algorithm in the digital signal processing is the most superior. At last,this conjecture is correct by the simulation of MATLAB and analyzing the simulation data.
