hi all
How can i generate pseudorandom Gaussian binary sequence ( comprising 1 and -1 {±1} ) with zero mean and one variation in MATLAB?
Thanks in advance
A binary signal cannot have a gaussian distribution, since its pdf is discrete, ie; you get two values for the probability at x=+1 and x=-1, and everywhere else it is zero.
However, you can generate a binary signal that is approx 50% of the time +1 and 50% -1, by just
y = sign(rand(1, 1000) - 0.5)
It will have variance =1 since square of each value is +1, anmd mean will be around 0.
