Abstract:
A convolutional interleaver included in a time interleaver, which performs convolutional interleaving includes: a first switch that switches a connection destination of an input of the convolutional interleaver to one end of one of a plurality of branches; a FIFO memories provided in some of the plurality of branches except one branch, wherein a number of FIFO memories is different among the plurality of branches; and a second switch that switches a connection destination of an output of the convolutional interleaver to another end of one of the plurality of branches. The first and second switches switch the connection destination when the plurality of cells as many as the codewords per frame have passed, by switching a corresponding branch of the connection destination sequentially and repeatedly among the plurality of branches.

Claim (Index 3):
A convolutional interleaving method comprises:\n switching, by a first switch, a first connection destination of an input terminal of the convolutional interleaver to one end of one of a plurality of branches, a number of which is same as a number of interleaving units on which a cell to be interleaved is disposed; providing a plurality of FIFO (first in, first out) registers in the plurality of branches except the first branch, wherein a number of FIFO registers is different among the plurality of branches and each lower branch adds an additional FIFO register; and switching, by a second switch, a second connection destination of an output terminal of the convolutional interleaver to the other end of one of the plurality of branches, wherein the topmost branch does not include an FIFO (first in, first out) registers, the branch lower than the topmost branch adds another FIFO (first in, first out) registers to the branch at one higher stage, and the branch includes FIFO (first in, first out) registers, such as 1, 2, 3, and 4, toward the bottom, and wherein in the switching by the first switch, the first switch switches the first connection destination of the input terminal when the plurality of cells as many as codewords per frame have passed, by switching a corresponding branch of the first connection destination sequentially and repeatedly among the plurality of branches, and in the switching by the second switch, the second switch switches the second connection destination of the output terminal when the plurality of cells as many as the codewords per frame have passed, by switching a corresponding branch of the second connection destination sequentially and repeatedly among the plurality of branches, and the first switch and the second switch always point to identical branches.
