An Innovative Input Grouping and Sharing Approach for Low Complexity 32-Point FFT Implementation

The objective of “An Innovative Input Grouping and Sharing Approach for Low Complexity 32?Point FFT Implementation” is to propose a novel FFT architecture that uses an input grouping method to reduce the number of multiplications with FFT twiddle factors and an input partial sum sharing scheme to reuse hardware resources and minimize adder cost, thereby achieving a low?power, low?complexity, and efficient 32?point FFT design suitable for digital signal processing applications.
