摘要
离散傅立叶变换是数字信号处理中一种很重要的数学工具,它可以描述离散信号的时域与频域的关系,在数字信号处理中有着重要的地位,应用十分广泛。本文首先把一维PM算法推广到高维,并在此基础上结合向量编码算法,进而推导了高维的基-8 PM向量编码算法。
The discrete Fourier transform（ DFT） is a kind of important tools of mathematics which can describe the relation between the time-domain and frequency-domain of discrete signal,and it has very important stage in digital signal processing and has been applied to many aspects widely. In this paper,the one-dimensional PM algorithm is extended to multidimension,based on vector coding algorithm,and then the multidimensional DFT of the R-8 PM vector coding algorithm is derived.
