What is convolution code with example?
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.
How do you write a convolution code?
The Signal Processing Toolbox™ software has a function, cconv , that returns the circular convolution of two vectors. You can obtain the linear convolution of x and y using circular convolution with the following code. ccirc2 = cconv(x,y,6);
Why use convolutional codes?
The ability to perform economical soft decision decoding on convolutional codes, as well as the block length and code rate flexibility of convolutional codes, makes them very popular for digital communications.
