Figure 5.27 - Simulated performance of a CRSC code with
8
punctured states, as a
function of its rate.
Puncturing is therefore a flexible technique, and easy to implement. As the
encoder and the decoder remain identical whatever the puncturing applied, it
is possible to modify the encoding rate at any moment. Some applications use
this flexibility to adapt the rate, as they go along, to the channel and/or to the
importance of the data transmitted.
