Assignment:
Consider that the rate 2/3 trellis-coded system is used over a binary symmetric channel (BSC). Assume that the initial encoder state is the 00 state. At the output of the BSC, the sequence Z= (1 1 1 0 0 1 1 0 1 0 1 1 rest all "0") is received.
(a) Find the maximum likelihood path through the trellis diagram and determine the first 6 decoded information bits. If a tie occurs between any two merged paths, choose the upper branch entering the particular state.
(b) Determine if ally channel bits in Z had been inverted by the channel during transmission, and if so, identify them.
(c) Explain how you would proceed with the problem if the channel were specified as a Gaussian channel instead of a BSC.
Provide complete and step by step solution for the question and show calculations and use formulas.
