Consider a symbol s, with zero mean, E{s}=0, variance 1 and amplitude A=2, such that, .
I want to generate a random real number s. Kindly help. Thanks in anticipation.

(rand()*2-1) * A
would be uniform distribution with mean 0 and in the range -A to +A.
Unfortunately it will not have the right variance, so you will not be able to use uniform random distribution.

According to my understanding you want to generate random real numbers s for some distribution with specific mean and variance. . Since the distribution is not mentioned, let us assume that you want to generate random symbols from the Normal Distribution, you can refer to the following link,
Hope this helps!

Normal distribution cannot generate in a range -- not unless you use a truncated normal distribution.
betarnd can give continuous random numbers within a range and that are non-uniform.
