Repeat Problem 12.23 for the worst-case partial-band interference channel.
Problem 12.23
The TATS signal described in Section 12.3-3 is demodulated by a parallel bank of eight matched filters (octal FSK), and each filter output is square-law-detected. The eight outputs obtained in each of seven signal intervals (56 total outputs) are used to form the 64 possible decision variables corresponding to the Reed-Solomon (7, 2) code. Determine an upper (union) bound of the code word error probability for AWGN and soft-decision decoding.
