For this code, d free =5,R =1/2, and Kb(C) = 1, which means that the nominal coding gain is γ c(C)=5/2 Convolutional codes are a bit like the block codes discussed in the previous lecture in that they involve the transmission of parity bits that are computed from message bits. Unlike block codes in systematic form, however, the sender does not send the message bits followed by (or interspersed with) the parity bits; in a convolutional code, the Y. S. Han Introduction to Binary Convolutional Codes 1 Binary Convolutional Codes 1. A binary convolutional code is denoted by a three-tuple (n,k,m). 2. n output bits are generated whenever k input bits are received. 3. The current n outputs are linear combinations of the present k input bits and the previous m×k input bits.

Conv. Codes in Wireless Communications • Why are convolutional codes often used in wireless communication systems? – Block codes typically have algebraic decoders. • These decoders operate on hard decisions (0’s and 1’s, or equiva lents) – Convolutional decoders can use soft -decision decoding.
