Develop a computer program to verify the performance curves shown in Figure 8.17. Compare the performance of the non-coherent FSK system to the performance of both coherent FSK and coherent PSK with a modulation index of 1. We will show in the following chapter that the bit-error probability for coherent FSK is Pr NOBT P, = Q

and that the bit-error probability for coherent BPSK with a unity modulation index is

2Pr P, = Q N,BT

where B_T is the system bit-rate bandwidth. Compare the results of the three systems studied in this example for n = 8 and n = 16.

Figure 8.17

Pr NOBT P, = Q 2Pr P, = Q N,BT
