Hallo evedybody. I'm working with Simulink (discrete time) and I've to derivate a noisy signal. What is the best way to do this? Anyone could suggest me a proper choise for cefficients of a derivative filter? (for example: [z(n) + 3z(n-1) -3z(n-2) -z(

I?ve realised I wasn?t very correct in the description of my problem. In fact, I am working with Simulink, not MatLab code. I am doing a wind park modelation and its integration in the electrical grid. When I was testing the park with only one turbine, everything went ok.

Hi, What I forgot to mention was that before taking the signals into the workspace for performing cross correlation, you need make the SNR of the channel very high. Then the received signal would be same as the transmitted one with some delay added. This delay can be found by c

Is it possible to translate a M file into C code? I have played around with real time work shop but that only seems to work from simulink. I have a m script that performs discrete wavelet transformation and my c knowledge is not strong enough. Is it possible to convert it to C?

Does anyone know of an easy way (or any way) of manipulating m-file names using a matlab function. As a simple example: say I have a Simulink model which runs the m- file 'file1.m'. Now I also have three other files called 'file2.m', 'file3.m' and 'file4.m'. What I want to do

Hello guys, I don't know a lot about matlab simulink, so I was wondering if someone can help me so I can figure out the spectrum of an ofdm. I want the complex data out from the transmitter to be analogized separately- I mean the real and imaginary signals each one alone- then digitized by a sampling rate that is twice the value of the digital transmitted signal. Thanks in advance, Huss...
