Show that the noise components N 1 and N 1 for QPSK, given by Equations (10 6) and (10 8), are uncorrelated that is, show that E N 1 N 2 0 (Explain why N 1 and N 12 are zero mean ) (10 6) n(t) cos(27f t) dt N1 N N2 n(t) sin(27f t) di (10 8)

Question: Show that the noise components N 1 and N 1 for QPSK, given by Equations (10.6) and (10.8), are uncorrelated; that is, show that E[N

Show that the noise components N₁and N₁for QPSK, given by Equations (10.6) and (10.8), are uncorrelated; that is, show that E[N₁N₂] = 0. (Explain why N₁and N₁₂are zero mean.)
