Thank you barry for reply and can you please correct my Matlab code if i'm wrong :
x = [ 0.01 -0.5 0.02 0.5 0.003 0.8 1 0 0 0 -1 0 0.0001 0 0 0 ];
for i =1:numel(x)
Treshold = 0.85;
x_energy = abs((x).^2);
x_sort = sort(x_energy); % sorted in ascending order of energy
cum_energy...
Hello,
is there any algorithm for the peak finder in numeric signal for example if we have x = [ 0.01 -0.5 0.02 0.5 0.003 0.8 1 0 0 0 -1 0 0.0001 0 0 0 ] , as you see we have 5 peak sample ( -0.5 , 0.5 , 0.8 , 1 , -1 ) , these peaks must capture 80 % of energy of...
Hi ,
if we have channel impulse response = [0.4544 -0.0036 0.0065 -0.0107 0.0169 -0.0267] , how i can extract the path gain from the channel impulse response.

Hi ,
what's mean this kind of subcarrier mapping :
The logical frequency subcarriers 1 to 61 are mapped to the same numbered IFFT inputs while the logical frequency subcarriers –61 to –1(How can i mapping the complex Data into logical frequency -60 to -1: what's means the logical frequency -61...

Hello
I want to ask you friend what is the NCBPS(number of coded bit per symbol) and how we can get it if we have Ndsc(number data subcarrier)=100;and code rate 1/2;and QPSK Modulation
Regards,
Hello everyone
when we simulate stanadard like IEEE802.11a what we mean for NCBPS(number of coded bit per symbol)
and what is:
1- relation between the Number of data subcarier and NCBPS ?.
2- and the relation between code rate and NCBPS?
Hello
I'm doing my research on MB-OFDM system (for standard IEEE802.15.3a) i've download the Mathwork Model for this standard in :
**broken link removed**
i tried to make this model work but i still have error message of type :
Failed to load library 'uwb_lib' referenced by 'uwb/OFDM...
