Q33
A BPSK scheme operating over an AWGN channel with noise power spectral density of N_02, uses equiprobable signals s_1 ( t ) = 2ET ( _ct ) and s_2 ( t ) = 2ET ( _ct ) over the symbol internal (0, T). If the local oscillator in a coherent receiver is ahead in phase by 45° with respect to the received signal, the probability of error in the resulting system is
