Dwpt Based FFT and ITS Application to SNR Estimation in OFDM Systems
In this paper, wavelet packet (WP) based FFT and its application to SNR estimation is proposed. OFDM systems demodulate data using FFT. The proposed solution computes the exact FFT using WP and its computational complexity is of the same order as FFT, i.e. O (N log2 N). SNR estimation is done in...
