چکیده

The terms Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT) are used to denote efficient and fast algorithms to compute the Discrete Fourier Transform (DFT) and the Inverse Discrete Fourier Transform (IDFT) respectively. The FFT/IFFT is widely used in many digital signal processing applications and the efficient implementation of the FFT/IFFT is a topic of continuous research.

Automatic IP Generation of FFT/IFFT Processors with Word-Length Optimization for MIMO-OFDM Systems

A systematic approach is presented for automatically generating variable-size FFT/IFFT soft intellectual property (IP) cores for MIMO-OFDM systems. The finite-precision effect in an FFT processor is first analyzed, and then an effective word-length searching algorithm is proposed and incorporated in the proposed IP generator. From the comparison, we show that our analysis of the finite precisio...

FPGA Implementation of Inverse Fast Fourier Transform in Orthogonal Frequency Division Multiplexing Systems

In modern communication systems, Orthogonal Frequency Division Multiplexing (OFDM) systems are used to transmit with higher data rate and avoid Inter Symbol Interference (ISI). The OFDM transmitter and receiver contain Inverse Fast Fourier Transform (IFFT) and Fast Fourier Transform (FFT), respectively. The IFFT block provides orthogonality between adjacent subcarriers. The orthogonality makes ...
