A digital message x(nT ) with T = 1µs, has iid symbols with PMD

a) Find the message efficiency.

b) Find a source coding scheme in which the output message yn has a ternary alphabet and unit efficiency. What is the symbol period for yn?

c) Is it possible to find a channel coding scheme for yn that will allow transmission over a BSC with symbol period Tb = 400 ns and bit error probability Pbit = 10−2,

with an overall error probability
