A Low-Power 64-point FFT/IFFT Architecture for Wireless Broadband Communication

A Low-Power 64-point FFT/IFFT Architecture for Wireless Broadband Communication
A Low-Power 64-point FFT/IFFT Architecture for Wireless Broadband Communication
A low power 64-point FFT/IFFT architecture is developed for the application in OFDM based wireless broadband communication system. The proposed architecture satisfies the specifications of IEEE 802.11a and ETSI Bran. The architecture requires 25% multiplication and 86% addition/subtraction operation compared to the conventional Cooley-Tukey approach. This leads to power and area saving as well. The architecture is capable to perform FFT and IFFT without changing the internal coefficients which makes it highly suitable for practical applications.

Abstract

A low power 64-point FFT/IFFT architecture is developed for the application in OFDM based wireless broadband communication system. The proposed architecture satisfies the specifications of IEEE 802.11a and ETSI Bran. The architecture requires 25% multiplication and 86% addition/subtraction operation compared to the conventional Cooley-Tukey approach. This leads to power and area saving as well. The architecture is capable to perform FFT and IFFT without changing the internal coefficients which makes it highly suitable for practical applications.
