hello, please; how can I compute the FFT in simulink of a signal whose length is not a power of two, and that the FFT must have the same length as the signal. and that because I see that we can not do that with the Poas FFT block available in Simulink, thank you in advance.
For length N input vector x, the DFT is a length N vector X, with elements:
N
X(k) = sum x(n)*exp(-j*2*pi*(k-1)*(n-1)/N), 1 <= k <= N.
n=1
so , if N change, then X(k) will not be the same, because all elements are divided on N into exp.
hello, I really need help, I want to simulate the physical layer of the new technology LTE. More specify the uplink, using the technique SC-FDMA for transmission, my questions are:
I want to work in the bandwidth of 5MHz, so:
1 - the number of carriers employed is 301 (with CD), so the size...

hello, dear cruiser_sun can you send me your model of OFDMA system, I really need it, because I just started my year-end project about LTE, help me please, here is my email address: mrd9991@hotmail.fr ; thank you in advance.
i want to know how can i demonstrate and simulate with matlad this expression of power received signal, in multipath transmission:
p(f) = 2Δf { Σ(i=1 to N) Ai (f)² + ( Σ (i=1 toN)Σ (j=1 to N) Ai(f).Aj(f)/ k.ΔLij.Δf)* [cos(k.ΔLij.fc).sin(k.ΔLij.Δf)] }
Where:
k = 2.pi/c (c: velocity...
hi everybody, i am beginning my final study project, it is about channals models, like you know the beginning is difficult, i need your help. i have to understand deffrents methods, rayleigh; rice, ... awgn, please can yous give me web adresse , cours, titles of books,or anything cans help me...
