matlab rand generator
some helpful replies, thanks. The web page I mentioned above generates the random data through radioactive decay. I guess its along the same lines as using noise from electrical components.
how to build a random generator in matlab
I didn't think about downloading random data instead of generating it ... I will try that thanks. I found the following web page if anyone is interested h**p://www.fourmilab.ch/hotbits/ where you can download random bits.
matlab random generator
Does anybody know where to get a Matlab file that generates very close to independent random samples? If you look at the higher order statistics of rand or randn, they are not as independent as I would like them to be. Any suggestions?
Re: About sampling
oversampling also helps with digital signals in noise by providing several instances of the message symbols instead of just one. In a frequency selective channel, it helps by being able to use Fractionally spaced equalizers.
Re: Please help!!
Just try this
samples=10000; %whatever number of samples you want
Z=rand(1,samples);
Z(find(Z<=0.25))=-1;
Z(find(Z>=0.75))=1;
Z(find(Z>=0.25&Z<0.5))=-j;
Z(find(Z>=0.5&Z<0.75))=j;
