In
telecommunication, a
convolutional code is a type of
error-correction
code in which (a) each
m-
bit information symbol (each
m-
bit string[?]) to be encoded is transformed into an
n-bit symbol, where
n >
m and (b) the transformation is a function of the last
k information symbols, where
k is the constraint length of the code.
Note: Convolutional codes are often used to improve the performance of radio and satellite links.
