10.8-2 Asourceemits four equiprobable messages m1, m2, m3, and m4, encoded by signals s1 (t), s2(1), s3(t), and s4(t), respectively, where s1 (t) = 20/2 sin TM s2(t) = 0 s3 (1) = 10/2 cos $4(1) = – 10/2 cos TM = 20 -t Each of these signal durations is 0 <t < TM and is zero outside this interval. The signals are transmitted over AWGN channels. (a) Represent these signals in a signal space. (b) Determine the decision regions. (c) Obtain an equivalent minimum energy signal set. (d) Determine the optimum receiver. -18
