Hello,
I suggest to do like this: theoritical BER for BPSK over gaussian channel : BER=0.5*erfc(sqrt(Eb/N0)) = Nberrors/TotalBits
TotalBits = 0.5*erfc(sqrt(Eb/N0)) / NBerrors (so can determine the TotalBits from your SNR and the Desired Number of errrors)
Best Regards...
hello,
I want two implement a filter in s-domaine in veriloga, for example ( (s-1)/(s-2) )*exp(-s*Tau). I Know how to do it
with zero/pelo but my problem is the delay element exp(-s*Tau). Thanks very much for your help.

Hi Ahmed,
In normalized spectrum means sampling frequency = 1 you have just to multiply by
the sampling frequency to get it in hz. or use directly
freqz(h_lp,1,1024,Fs) Fs is sampling frequency if you put Fs=1000 hz you get
the cut frequency = fc_l * Fs
hM is the auto correlation matrix.
First hAutoCorr = conv(ht,fliplr(ht)); this the autocorrelation of ht you can use xcorr(ht) instead:
hAutoCorr(3) is the maximum that should form the diagonal of correlation matrix hM
the number 2*kk+1 is the equalizer...
Hi,
if you do this
f=(0:50)/50
plot(f,Mag)
your plot will be normalized and you see the relevant part which is 0 to 0.5
the part higher than 0.5 is the negative spectrum (0.5 is the nyquist frequency)
your filter is correct.
best regards
