摘要
重采样技术是数字信号处理领域研究的问题之一。利用重采样技术可以有效地实现均匀到均匀、非均匀到均匀的插值。在讨论重采样技术原理及其快速实现方法的基础上 ,对重采样插值技术的应用 ,即Stolt插值问题和DLFMS(DirectLFMSample)插值问题进行了研究 ;从收敛性、运算量两个方面比较 ,分析了重采样插值与多项式插值的性能 ,证明了重采样插值是一种收敛性好、计算量小 ,且便于实现的插值方法。
The need for precise interpolation is more popular in digital signal processing. The resampling technique can implement a nonuniform-to-uniform, uniform-to-uniform interpolation. We first present the principle of resampling technique and study the application of resampling interpolation, such as Stolt interpolation and DLFMS interpolation. Furthermore, the performance of resampling interpolation is analyzed in detail.
