Q. 51 Let 
be the BER of a BPSK system over an AWGN channel with twosided noise power spectral density 
. The parameter
is a function of bit energy and noise power spectral density.
A system with two independent and identical AWGN channels with noise power spectral density is shown in the figure. The BPSK demodulator receives the sum of outputs of both the channels.
If the BER of this system is 
, then the value of b is ____.
