In a digital communication system, probability density function
of the two level signal received in the receiver is:
PR(v) =
PS(v)*PN(v) =
[0.4δ(v+1) + 0.6δ(v-4)]*η(v). And ,
η(v) is the noise that added to the message sign as the
additive Gaussian noise with a value of zero and an effective value
of 3.
(* symbol means convolution process, in the solution of this
problem you can use the below Q function table.) ,
η(v) =
A) Plot the probability density...
