Abstract
A method and an apparatus for controlling an interleaving depth are provided. The interleaving depth controlling method includes performing a modulo operation on an interleaving depth selected to be less than or equal to a maximum interleaving depth and a total number of codewords to obtain a number of remaining codewords; and comparing the total number of the codewords to the interleaving depth, when the number of the remaining codewords excludes “0”, to control the interleaving depth.
Claims13
A processor-implemented method in a communication system using an interleaving depth control, the method comprising:
- performing a modulo operation on an initial interleaving depth and a total number of codewords;
- and
- applying a first interleaving for (NB−2) interleaving blocks, a second interleaving for (NB−1)th interleaving block, and third interleaving for (NB)th interleaving block when the initial interleaving depth is less than the total number of the codewords and a sum of a result of the modulo operation and the initial interleaving depth is greater than a maximum interleaving depth,
- wherein an interleaving depth of the first interleaving is different from an interleaving depth of each of the second interleaving and the third interleaving.
A digital communication apparatus, comprising:
- one or more processors configured to:
- perform a modulo operation on an initial interleaving depth and a total number of codewords, and
- apply a first interleaving for (NB−2) interleaving blocks, a second interleaving for (NB−1)th interleaving block, and third interleaving for (NB)th interleaving block when the initial interleaving depth is less than the total number of the codewords and a sum of a result of the modulo operation and the initial interleaving depth is greater than a maximum interleaving depth,
- wherein an interleaving depth of the first interleaving is different from an interleaving depth of each of the second interleaving and the third interleaving.
