Hello, Guys
I am looking for a fast double summation method for the following calculation.
X=[0:N-1]; Y=[0:N-1];
Z=ExEy[exp(-(X(n)-Y(n))^2)];
Thus, in MATLAB,
X=[0:N-1]; Y=[0:N-1];
for n=1:N
Zy(n) = sum(exp(-(X(n)-Y(:))^2)) / N;
end
Z = sum(Zy) / N;
As shown above, firstly I tried "for...
Hi, all
I want to generate signal sources which can be transmitted through wireless channel.
The signal sources occupy over M narrowband channels with each center frequency of fm and each power of Pm respectively. And each narrowband channel's bandwidth is B.
By this work, I would like to...
Re: What is the difference of OFDM in AWGN / Multipath fadin
Does that mean OFDM has worse BER performance?
Because longer OFDM symbol degrades Es/No, does it have worse performance?
EsNo = EbNo * rate; % non-ofdm case, rate= coding_rate * mod.order, e.g. 1/3 turbo and QPSK ->...
I have the same problem with yours.
It makes me very confusing when I use the rayleighchan() in time/frequency domain.
I also want to implement ideal channel estimation by extract frequency channel response.
In the case of implementation on simulink, actually there is the same simulink block...
Hello~!
I'm studying priciple of OFDM.
OFDM is crucial in multipath fading environment because it has ability to resolve selective fading channel into flat fading by one-tap equalizer.
Then, in AWGN environments, is it no benefit using ofdm?
Does it mean that both non-ofdm and ofdm system...
