Question: Suppose a communication receiver consists of two components, a demodulator and a decoder. The demodulator is based on a Markov model of the combined modulator

Suppose a communication receiver consists of two components, a demodulator and a decoder. The demodulator is based on a Markov model of the combined modulator and channel, and the decoder is based on a Markov model of a forward error correction code. Discuss how the turbo principle may be applied to construct a joint demodulator, decoder for this system.
