## Convolutional Codes

We call convolutional encoding when the encoding scheme depends not only upon the current message, but also upon a certain number of preceding messages. Hence, the convolutional encoding uses memory. Let $latex D$ be a variable of a polynomial, which also a delay operator; $latex \mathbb{F}_{2}(D)$ is the set of all binary polynomials in the … Continue reading Convolutional Codes
