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...
