EE 421 – Fall 2010
Homework 3,
due Thursday December 2nd
Problem 1
Consider the encoder shown in the figure below.
•
Determine the encoder rate R
c
, the parameters n and k, the encoder memory m and
constraint length K
•
Determine the effective rate if L=1000 bits are transmitted
•
Determine the
k generating vectors (or impulse responses g
i
)
•
Draw the state diagram, specifying the state labels, the input bit and the output bits for each
transition
•
Determine the codeword associated with the input sequence 11101 (where the sequence of
three ones are the initial input)
Problem 2
Consider the encoder shown in the figure below.
•
Determine the encoder rate R
c
, the parameters n and k, the encoder memory m and
constraint length K, say if the encoder is systematic
•
Determine the effective rate if L=300 bits are transmitted
•
Draw the state diagram, specifying the state labels, the input bit and the output bits for each
transition
•
Determine the codeword Y=Y
