Question:
Consider a communication channel as shown in Figure 9.2. We can model the communication over this channel as follows. At time n, a random variable Xn is generated and is transmitted over the channel. However, the channel is noisy. Thus, at the receiver, a noisy version of Xn is received. More specifically, the received signal is Yn = Xn +Wn, where Wn ∼ N(0,σ2) is the noise added to Xn. We assume that the receiver knows the distribution of Xn. The goal here is to recover (estimate) the value of Xn based on the observed value of Yn.
