What is OFDMA?
Orthogonal Frequency Division Multiple Access. It has something to do with the way cell phones transmit signals.
Difference between the DFT and the FFt?
A Discrete Fourier Transform is simply the name given to the Fourier Transform when it is applied to digital (discrete) rather than an analog (continuous) signal. An FFT (Fast Fourier Transform) is a faster version of the DFT that can be applied when the number of samples in the signal is a power of two. An FFT computation takes approximately N * log2(N) operations, whereas a DFT takes approximately N^2 operations, so the FFT is significantly faster simple answer is FFT = Fast DFT
What is the meaning of bonding energy in solid?
meaning of bonding meaning of bonding
What is the term for the secondary meaning of words?
The first meaning of a word is referred to as "denotative meaning". This is the dictionary definition. The second meaning of a word is referred to as "connotative meaning". This is not in the dictionary.

Need of fft?
FT is needed for spectrum analysis, FFT is fast FT meaning it is used to obtain spectrum of a signal quickly, the FFT algorithm inherently is fast algorithm than the conventional FT algorithm
What is the meaning of inter cell interference?
due to OFDMA some interference occurs which limits extention service of mobile
What are there advantages and where are there used fft?
because they have a high speed compared to fft
What is traffic load sector?
ofdma frequency range
What are there advantages and where are there used?
FFT reduces the computation since no. of complex multiplications required in FFT are N/2(log2N). FFT is used to compute discrete Fourier transform.
What is the basic difference between ofdma and sc-fdma?
The basic difference between OFDMA and SC-FDMA is that, there there is an additional block of N point DFT before the sub-channel mapping in SC-FDMA. This will effectively reduce the PAPR, thus the power amplifier will have a lesser linear range in SC-FDMA when compared with OFDMA
How do you plot frequency spectrum using fft function in MATLAB?
plot(abs(fft(vectorname)))the FFT function returns a complex vector thus when you plot it, you get a complex graph. If you plot the absolute value of the FFT array, you will get the magnitude of the FFT.
What is the need of FFT?
There's no need for it.
Why FFT is faster than DFT?
FFT is faster than DFT because no. of complex multiplication in DFT is N^2 while in FFT no. of complex multiplications are N/2(log2N). for example if N=8 no. of complex multiplications required in DFT are 64. while no. of complex multiplications required in FFT are 12 thus reduces computation time.
