Hi All, 1) I have a windows application created using .NET, C# to be specific. 2) I have two waveforms X and Y. X is input waveform and Y is output. X and Y are nothing but 1048 samples of complex data in an Array. 3) I have FFT algorithm with me. 4) Now can anyone help me calculate the Transfer function and Coherence using Matlab. I think Matlab has some function call to calculate...

Hi, everyone! I use TMS320c6713 DSP. I compared result of complex fft library in TI DSP with result of complex fft in Matlab. Those waveform in frequency domain are similar, but exactly not matched. It means.. Range of result in DSP library is wider than one in Matlab. Why? Regards.

Hello all, I am a newbie to Matlab and DSP. I am trying to write a Matlab code that simulates the effect of IEEE 802.11a interference on UWB communication. The question is wrt the Matlab implementation of the received signal. I want to implement the code as follows: r(t) = UWB_ChannelGain * s(t) + AWGN + 80211a_ChannelGain*I(t) where, r(t) = received signal s(t) = transmitt...

[Question] A problem originated in engineering: H is a (N*SF+L-1)*(N*SF) complex matrix and is generated with a Matlab command H=filter(h,1,[eye(N*SF);zeros(L-1,N*SF)]) where h is a L*1 complex vector. C is a (N*SF)*(N*K) complex matrix and is generated with a Matlab command C=kron(eye(N),c) where c is a SF*K matrix whose columns are Walsh codes. I find out with a Matlab program that C'*H'*H...

Hi all In the GUI in matlab i am creating a single sin wave with a freq between 1KHz-15Khz in steps 1KHz. In matlab iam using the fft() function to get the freq specturm and then get mag and find the peak which will give me the freq. But i need to make a GUI version of this and cant seem to get any thing to work . can anyone help or give me a website to look at. Thanks James_Bond

Hi, I'm trying 2 realize the function "butter" as iin matlab, using scilab. So instead of [a, b]=butter(ord,[int1* 2/Freq int2*2/Freq]); I write the following: hz=iir(ord,'lp', 'butt', [int1/Freq int2/Freq], [0 0]); a=coeff(denom(hz));a=a($:-1:1); b=coeff(numer(hz));b=b($:-1:1); and I don't get the same results as in matlab. What do I do to get the same results? p.s. I'...

Hi all, I understand the subject of similiarity of signals has dsicuss many of times in this forum however i still need some valuable advice and help. My problem is that i am trying to find the percentage of similiarity of 2 signals using matlab? Say in matlab i have just a variable called signal1 and signal2 both of size [1 by 5000] these signal 1 and signal 2 are EEG signals. I just w...

Hello, would any one out there can help me how to appy IIR to filter an 256x256 image using IIR in Matlab? is there any function for it (I mean 2 D IIR filter). I have to use a IIR filter to filter a image and it is required that I do it in Matlab. I have done it in C and using difference equation: y(m,n)=a1*x(m,n)+a2*y(m-1,n)+..... and everything is fine. Now I have to do it in ...

Can anyone help me? I can't find enough information about standard Inmarsat-C. I found information about Inmarsat-C in the group FAQ-Inmarsat, but this information isn't correctly. I built Matlab receive model and I use Matlab BPSK demodulator. I tryied with this demodulator, afterthat I changed it with Matlab DBPSK demodulator, but results were mostly same. I didn't see synchroword and struc...

Im trying to implement an 8th order Butterworth low pass filter in Matlab. I know you can design filters in matlab, but because of the specific implementation of my project, im doing with no matlab functions in an m file. So, the problem im having is that the input before filtering is EXACTLY the same as the output... what am I doing wrong? The sampling frecuency is 44100 hz. The filter cutoff...
