a. A Hamming (7, 4) code is used to correct errors on a binary symmetric channel with error probability ?. What is the probability of decoding error? (A binary symmetric channel is a binary channel that has the same probability of error when a zero is transmitted as it does when a one is transmitted.)
b. If the code is used only to detect errors but not correct them, what is the probability of undetected error?
c. AReed-Solomon (7, 5) code is used to correct errors on an octal symmetric channel with error probability ?. What is the probability of decoding error?
