Title: Parallel bit interleaver
Inventor: MIHAIL PETROV
IPC: H03M13/27
Filed: 2019-07-29
Abstract: To provide an interleave method realizing efficient interleave applied to the codeword of pseudo circulation low density parity check code.SOLUTION: Bits of a codeword of N×Q bits constituted of N circulation blocks consisting of Q bits, respectively, are rearranged and divided into multiple constellation words each consisting of M bits. Assuming the remainder of dividing N by M is X, a first rule for reordering the bits applied to N'=N-X circulation blocks is different from a second rule for reordering the bits applied to X circulation blocks. The first rule is a rule performing column-row permutation processing, equivalent to writing the Q bits of each circulation block in one row direction out of a queue of M rows, and reading the Q bits in the column direction for N'=N-X circulation block. The second rule is a rule not performing bit permutation processing for the X circulation block.SELECTED DRAWING: Figure 45
