    Given a polar non-return to zero waveform, using +2 V and –2 V for representing binary ‘1’ and ‘0’ respectively is transmitted in presence of white Gaussian noise with variance 0.4V 2 .
    P (1) = 0.4, P (0) = 1−P(1) = 0.6
    Average probability of error in given as,
    On solving, the optimum threshold for MAP receiver is obtained as,
    Equation (i) may be used as standard equation to find optimum threshold for minimum probability of error
    Hence, the minimum probability of error occurs for the optimum threshold of Vth = 0.0405 V.
