Hi al,
how would you guys classify blind beamforming?
1-based on SOS(second-order statistics) and on HOS(higher-order statistics)
or
2-Blind beamforming for stationary signals and blind beamforming for cyclostationary signals?
or sth else
thx in advance!
Haha, thx klystron, but actually most of the companies recruiting in school require Linux knowledge...

Hi RetroTechie
Thank you very much for your detailled explanations. i really appreciate and I am going to...

Hi Mileoung,
checkthis out . it is about kurstosis(4th order statistics) maximization for BSS

Hello,
I am recently interested in installing Linux, since everyone around me, seems to understand it and think it's *** OS. But i still don't understand the benefits of it?
I sit because it does not get viruses?
because the screen is black?
because you have to program everything yourself?
I...
Hi all,
Please help me answer this question.
How can i represent my rayleigh multipath channel in FD (frequency domain) when i have it in TD(time domain).
I created it using raileychan in matlab, but obviously i cannot directly apply fft here since it is a structure.
Please help me...
Thanx in...
Hi all,
please help me with algorithms or steps to take in estimating a channel in 2D. I already did so in frequency domain . that is by using LS method. very simple, but i want to use a more complex system so maybe i will have to use 2D wiener or 2x 1D wiener, i just don't know how to do...
Hi all,
I am trying to estimate the channel in frequency domain of a 2x2 MIMO channel
The problem is the way i insert pilot is like this:
at the position on antenna 1 where a pilot is installed, on the same position on antenna 2 i put a zero , to ease LS channel estimation.
But this causes a...
for rayleigh:
delay=sort(randint(1,num_path,[1 round(carrier_prefix_length)]))*ts;
pd=sort(randint(1,num_path,[-20 0]),'descend');
h=rayleighchan(ts,fd,delay,pd);
for AWGN:
noisy=awgn(signal,SNR,'measured');
check these two links, i haven't read them myself but i believe it can help you partly
