Example of Generating a Convolutional Code
The code-rate, Rc = k/n = 1/2 . The input string is streamed from right to left into the encoder. From the above example, we can see that any particular binary convolutional encoder is associated with a set of binary inputs, a set of binary outputs and a set of states.
What is convolutional code?
Convolutional coding is a widely used coding method which is not based on blocks of bits but rather the output code bits are determined by logic operations on the present bit in a stream and a small number of previous bits.
What is free distance of a convolutional code?
Specifically, the free distance of a convolutional code is the difference in path metrics between the all-zeroes output and the path with the smallest non-zero path metric going from the initial 00 state to some future 00 state.
What is difference between block codes and convolutional codes?
Digital binary coding schemes can usually be classified into two types: block code and convolutional code. In [1] , convolutional code, compared to block code, can control and correct errors better. Most of the existing designs use Cyclic Redundancy Check (CRC) to correct errors. ...
