We show that this algorithm can be easily implemented by using complex multiplications combined with fast Fourier transform (FFT) and inverse FFT (IFFT) operations. We perform comparisons with several representative algorithms and show that the proposed technique can be used to achieve a good trade-...
I am trying to use the time domain plot to determine the magnitude and the phase difference between the input and output signal, as opposed to using the bode function to output the mag and phase. How would I go about doing that. VBBV 2021...
we add the "negative" frequencies of our simulation (which are all zero), and set our DC term equal to the average amplitude of our frequencies. After applying the IFFT and correcting the order of our array (for more information, read the documentation of numpy.fft.ifft), we obtain the ...
based on a difference in an amount of time between the SFN initialization time of the reference cell and the previously received SFN initialization time of the reference cell, determining that the SFN initialization time of the reference cell has changed; and means for processing the timing synchro...
FFT(Fast Fourier Transform) to convert the digital signals divided by frame into a signal1 and a signal2 in a frequency domain; enabling a mobile phone to determine a cut-off frequency(615); enabling a phase difference calculator to calculates a phase difference between the signal1 and the ...
Both OFDM and OFDMA is used to achieve high data rate transmission over the air. With OFDMA system can support more subscribers with sub channelization concept compare to OFDM. Both OFDM and OFDMA is implemented using IFFT and FFT operation at transmitter and receiver respectively. For OFDM ...
The figure-5 depictsOFDM modulationtransmitter with signal spectrums. OFDM stands for Orthogonal Frequency Division Multiplexing. It usesIFFT and FFT equations>>in order to transform frequency domain vector to time domain vector and vice versa. ...

First, based on the broadband that is typical of blast waves, the peak frequency of the P-wave was obtained in the time–frequency domain, taking advantage of the difference in the propagation speed of the P-wave, S-wave, and the surface wave. Second, the phase difference between two ...
The 1H-NMR showed polysaccharide peaks between δ 3.50–4.20 ppm and XRD diagrams indicated their amorphous nature. Future works will focus on the quantitative analysis, biological activity and possible use of TSP as a drug delivery system. Keywords: tamarind seed polysaccharide (TSP); Tamarind ...
