A coherent binary phase-shift keyed (BPSK) transmitter operates at a bit rate of 20 Mbps. For a probability of error (P_e) of 10^-4 and given carrier-to-noise $$\left( {\frac{{\text{C}}}{{\text{N}}}} \right)$$ density ratio of 8.8 dB, determine energy of bit-to-noise $$\left( {\frac{{{{\text{E}}_{\text{b}}}}}{{{{\text{N}}_0}}}} \right)$$ density ratio for a receiver bandwidth equal to the minimum double-sided Nyquist bandwidth.
