Fast Adaptive Fourier Transform and Its Application in Multi dimensional Data Compression

介绍了一种新的用于多维数据压缩快速自适应付里叶变换算法 ,并将其性能与经典的算法如付里叶变换和哈达玛变换算法的性能进行了比较 。

This paper introduces a novel algorithm of fast adaptive Fourier transform (AFT) for multi dimensional data compression, and compares its performance with some classical algorithms such as discrete Fourier transform (DFT) and Hadamard Transform (HT). Simulation results indicate that the presented algorithm has a stronger capacity of data compression.
