Let \(Q\left( {b\sqrt \gamma } \right)\) be the BER of a BPSK system over an AWGN channel with two-sided noise power spectral density N0/2. The parameter γ 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 N0/2 is shown in the figure. The BPSK demodulator receives the sum of outputs of both channels.
If the BER of this system is Q(𝑏√𝛾), then the value of b is _______
