Consider antipodal signaling with amplitude imbalance. That is, a logic 1 is transmitted as a rectangular pulse
Question:
Define the ratio p = A2 / A1 and note that the average signal energy, for equally likely 1s and 0s, is
(a) Show that the error probability with amplitude imbalance can be written as
(b) Plot PE versus z in dB for p2 = 1, 0.8, 0.6, 0.4, respectively. Estimate the degradation in dB at PE = 10-6 due to amplitude imbalance for these values of p2.
