【应用笔记】DFT/IDFT参考设计(DFT/IDFT Reference Design)
离散傅里叶变换(DFT)参考设计对一个复杂输入序列进行了一个离散傅里叶变换(discrete Fourier transform,DFT)或者一个逆离散傅里叶变换( inverse DFT)，并生成了一个复杂输出序列。
The DFT reference design performs a discrete Fourier transform (DFT) or
an inverse DFT (IDFT) of a complex input sequence and produces a
complex output sequence.
The reference design performs the functions for either a DFT in the uplink
or an IDFT in the downlink of a typical 3G long-term evolution (LTE)
physical interface (PHY) implementation

May 2007, version 1.0 Application Note 464



Introduction The DFT reference design performs a discrete Fourier transform (DFT) or
an inverse DFT (IDFT) of a complex input sequence and produces a
complex output sequence.

The reference design performs the functions for either a DFT in the uplink
or an IDFT in the downlink of a typical 3G long-term evolution (LTE)
physical interface (PHY) implementation

The design inputs the transform length coincident with the first validated
