3.3 A random variable that takes on values of a sequence of 4QAM symbols, I, is transmitted over a communication channel: 3, 0, 1, 3, 2, 0, 2, 1, 3, 0, 0, 2, 3, 1, 3, 0, 2, 1, 0, 3 The channel introduces additive noise, J, equivalent to adding the following values to the above symbol sequence: 0, 0, 1, 0, 0, 1, 1, 0, 0, 0, 0, 1, 0, 1, 0, 0, 0, 1, 0, 1 The addition is performed in modulo form. (a) Form the resulting sequence: I J modulo 4. Let K be the random variable that takes on these values. (b) Plot histograms for random variables I and K.
