Consider a rule represented by the parity-check matrix of Figure E7.20.

a. What are the identical values of n, m, k, wrow, and wcol? Is this rule symmetrical or irregular?

b. Draw the identical Tanner graph. Does it inclose 4-pass cycles?

c. Check whether the rule control "0011011" and "0011111" suit to this rule.

d. Suppose that the ruleword "0011011" is ordinary by the decoder. Derule it using the progress descriptive in Figure 7.21. Compare the fruit opposing your reply in disunite (c) overhead.

e. Repeat disunite (d) overhead for the event when "0011111" is ordinary. Again, compare the fruit opposing your reply in disunite (c).
