railway RRB JE (CBT I + CBT II) Mock Test 2024 Communication Systems Information Theory Entropy Coding
If the constraint length of an (n, k, L) convolution code is defined as number of encoder output bits influenced by each message bit, then the constraint length is given by -
1
L(n + 1)
2
n(L + 1)
3
n(L + k)
4
L(n + k)
