Hi, My email notification says that someone replied to my forum post "Help on Noise Correlation matrix" but instead I was redirected to this. I have no clue how...
Ya certainly my aim was to generate two gaussian noise sequences and show that they are uncorrelated then add some color to it afterwards and show that they are...
I tried using your expression but didn't see any difference. For complex vectors cross correlation, is hermetian transpose operation not needed? i.e. Rr1r2 = E[r1...
Thanks for the quick response. So that means for a real scenario we will never get a diagonal matrix. Fair enough!
Theoretically, the vectors should be gaussian distributed which should mean r1 and r2 are AWGN which further should imply that they are independent and hence r1...
I was trying to create a Noise Cross Correlation Matrix in Matlab by using the following code:N = 100; % Number of Samplesr1 = rand(1,N) + 1i*rand(1,N);r2 = rand(1,N)...
By mixing do you mean that i have to multiply "I" with a cosine wave at -10Hz and "Q" with a sine wave at -10 Hz to bring it to +/- DC? Or is it also possible...
For every bit I have generated 10 periods of sinewave with the corresponding phase([-1, 1] maps to [0, 90 degree phase]).. i.e. bitrate is 1 Hz => Symbol duration...
The following is the block diagram for my implementation and I am stuck at the receiver front end marked as "??".
Hi All, Thanks for shedding some light into my query. I have got the most of it, what you guys mean, and I appreciate it, but still have some bits left.I am using...
Hi All,I was trying to simulate a digital communication model with a complex rayleigh fading channel in Matlab.The Data is BPSK modulated and is multiplied with...
Alright! Now I understand what you mean! One last question or rather doubt. As far as simulating this matlab is concerned do I have to use hilbert transform or...
I have some doubts on option 2. That is, is it posssible to apply IQ demod to the same waveform attached above or I have to transmit I and Q for that? If I have...
Thanks for that. I tried to correlate in parallel by generating 8 sequences each for one phase. What I see is amplitude peaks for the intended symbols. But the problem...
Ya thats what I was exactly thinking :) ..to use a 8-way correlator. But the question is how to convert the phases into realizable bits?(since I wanted to implement...
But my question still stands the same.First thing I don't have an complex LO hence there wont be a complex valued baseband. Second thing the real sequence or the...
Absolutely, but thats what my question is that how to demodulate the phase information without having an complex waveform?Downconvert means to multiply with a carrier...
I exactly understand what you mean but what if you are constraint to using only real sequences for transmission and you have only one DAC and one LO i.e. no quadrature...
