N2 - It is hypothesized that the source is in the form of a discrete Markov chain and that the channel is a discrete memoryless channel. The receiver is a maximum a posteriori (MAP) receiver (detector). The redundancy between successive symbols of the Markov source is used by the MAP detector to provide some protection against channel errors. In this paper, the authors consider two variations of a given problem: (i) sequence MAP detection which is to determine the most probable transmitted sequence given an observed sequence and (ii) instantaneous MAP detection which is to determine the most probable transmitted symbol at a particular time given all the observations up to that time.
