Consider a signal that takes on discrete odd integer values with a total of 8 symbols being formed. The sequence is Sk = {-7A, -5A, -3A, -A, A, 3A, 5A, 7A). Each value in the set has an equal probability of being transmitted. The waveform is given by Pk (t) = Ek-0 SkP(t - kTs) with T, = 1ms the symbol period (Zero Crossing of Nyquist Pulse). Let p(t) = sinc (t). Calculate the following: a. The Power Spectral Density of the Pulse for A = 1 (V). b. The Power Transmitted. c. The scalar value of A to normalize the Transmit Power to 1 W. d. The Bandwidth of the Signal if we take it to the first zero crossing on the frequency axis. The Constellation of the Signal is herewith: -7A -5A -3A -A +A +3A +5A +7A
