| 摘 要： | 在许多声信号处理系统中,常常需要在一实序列的相邻两个样值之间进行快速离散内插.本文提出了一种基于FHT的离散信号快速内插算法.该算法所需的实乘次数只有Hsu-Lin算法实乘次数的60%左右,而实加次数还不到Hsu-Lin算法的60%.此外,它允许内插率L可为任意整数,且适用于并行处理.本文算法已用软件实现,对实际声信号处理行之有效.

| Abstract: | Fast discrete interpolation between successive samples of real sequences mayoften be required in acoustic signal processing systems. In this paper a fast interpolation algorithm for discrete signals based on FHT is proposed. This algorithm requires about 60% ofthe number of real multiplication operations and fewer than 60% of the number of real addition operations of Hsu-Lin algorithm. Besides,it permits of any integer-valued interpolationratio and it is appropriate for parallel processing. The proposed algorithm has been implemented by software and it is efficient in practical acoustic signal processing |
