In a ternary amplitude shift keying (ASK) communications system, there are three equally likely transmitted signals {s0,
Question:
X = a(i - 1) + N,
where a is a positive constant and N is a Gaussian (0, σN) random variable. Based on the output X, the receiver must decode which symbol si was transmitted.
