- In this paper, we present an efficient design and implementation of FFT algorithm which is an important part of OFDM system. 4k-FFT algorithm is proposed and implemented in field programmable gate arrays (FPGAs). We measure the quantization error of FFT algorithm. Measured results show the maximum quantization error of 6.793259/5.662575 (real/imaginary value in 12 stage MSB truncation), 3.112945/2.627586 (real/imaginary value in 12 stage LSB truncation), 0.000756/0.000458 (real/imaginary value in 6 stage LSB/6 stage MSB truncation). © 2012 IEEE.
