Mixed radix CORDIC FFT algorithm for OFDM WPAN applications

This electronic record portrays the technique for usage of Fast Fourier transform for wireless communication systems, like OFDM, digital video broadcasting, digital audio broadcasting, and worldwide inter-operability for microwave access. The high speed and low area FFT algorithm using CORDIC and radix 2⁁5 calculation is proposed here. CORDIC is fundamentally DSP application yet here it is utilized for twiddle component augmentation. Radix 2⁁5 fft calculation is utilized for lessening of complex duplication. The proposed computation minimizes the amount of multipliers. Plot outlines show that the FFT arranged by the proposed framework shows a lower hardware with more quality than existing systems. Our designed has a working frequency up to 420.203 MHZ. CORDIC computation is executed in both MATLAB and in Xilinx on Virtex-5.
