Abstract :
In this paper, authors extend the work of CORDIC-Friendly Fast Fourier Transform (FFT) architecture in [1]. Instead of optimizing each stage independently, a joint optimization of two stages of the CORDIC-Friendly FFT rotations is considered. At no additional hardware cost, the proposed scheme achieves up to 38 dB SQNR gain using two-iteration MSR-CORDIC when compared to the previous algorithm for different FFT lengths.
