Determine the separation in the values of ebn0nbspfor

Question

The values of Eb/N0 required to realize an average probability of symbol error Pe = 10^-4 for binary PSK and binary FSK schemes are equal to 7.2 and 13.5, respectively. Using the approximation

determine the separation in the values of E_b/N₀ for P_e = 10^-4, using: a. binary PSK using coherent detection and DPSK;

b. binary PSK and QPSK, both using coherent detection;

c. binary FSK using (i) coherent detection and (ii) noncoherent detection;

d. binary FSK and MSK, both using coherent detection.
