9 Threads found on edaboard.com: Hamming Matlab Code
In my OFDM system, I need to apply a hamming and Blackman window in frequency domain. My simulation is on matlab.
I've done a FFT of this window and did its convolution with my data in freq domain, but I'm not getting the desired results. :-(
Can anyone help me to do this the correct way ?

i need the matlab code of simple rayleigh fading channels for error correcting code (hamming code).
i need to pass the input codeword and obtain the output.
pls help me.

Hi, Please i need help with this matlab code.
i am using this melcept function for different samples of me saying the word "one"
here is my code
=wavread('one.wav'); %Read In Sample
i get an output for the different samples of me saying one as 54

You must to apply some checking code, as hamming, CRC, etc...
Here there are some examples with CRC coding :

I done in matlab a routine to determine to the hamming(7,4,1) code, the amount of syndromes equal to Zero.
You could perform some few changes to fit to your code.
% Program to generate all the input error patterns from 0000000 to 1111111
% and then calculate corresponding syndromes
d = ;
h =[ ; [ 0

I need to compare the(7,4) hamming coded bit error probability with the uncoded bit error probabity and a Q function.
The matlab code which i have compare the theoretial uncoded ber with hamming (7,4) code (...)

u can develope some basic encryption and decryption algorithms like RSA, CRC, hamming code for error handling etc. and can develop a crypto syatem.

I have plotted the spectrogram of linear FM signal using TFTB toolbox in matlab. Here is the code:
My questions are:
How to find peak values of the spectrogram for every time instant (when you have mesh plot)?
How to plot a graph for a constant frequency, that (...)
