TRANSMITTER AND PARITY PERMUTATION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17994846 titled 'TRANSMITTER AND PARITY PERMUTATION METHOD THEREOF
Simplified Explanation
The abstract describes a transmitter that includes a Low Density Parity Check (LDPC) encoder, a parity permutator, and a puncturer. The LDPC encoder encodes input bits to generate parity bits. The parity permutator performs parity permutation by interleaving the parity bits and group-wise interleaving a plurality of bit groups. The puncturer punctures some of the parity bits in the group-wise interleaved bit groups.
- The transmitter includes a LDPC encoder that encodes input bits to generate parity bits.
- A parity permutator is used to perform parity permutation by interleaving the parity bits and group-wise interleaving a plurality of bit groups.
- The puncturer is responsible for puncturing some of the parity bits in the group-wise interleaved bit groups.
- The parity permutator group-wise interleaves the bit groups in a specific order, positioning some of the bit groups at predetermined positions and leaving the remainder of the bit groups without a specific order within the group-wise interleaved bit groups.
Potential Applications
- This technology can be applied in wireless communication systems.
- It can be used in satellite communication systems.
- It can be implemented in digital television broadcasting systems.
Problems Solved
- The transmitter solves the problem of efficiently encoding input bits and generating parity bits.
- It addresses the issue of interleaving and puncturing parity bits in a group-wise manner.
Benefits
- The transmitter provides an efficient and effective way to encode input bits and generate parity bits.
- It allows for flexible interleaving and puncturing of parity bits.
- The technology can improve the performance and reliability of wireless communication systems.
Original Abstract Submitted
A transmitter is provided. The transmitter includes: a Low Density Parity Check (LDPC) encoder configured to encode input bits to generate parity bits; a parity permutator configured to perform parity permutation by interleaving the parity bits and group-wise interleaving a plurality of bit groups including the interleaved parity bits; and a puncturer configured to puncture some of the parity bits in the group-wise interleaved bit groups, wherein the parity permutator group-wise interleaves the bit groups such that some of the bit groups are positioned at predetermined positions, respectively, and a remainder of the bit groups are positioned without an order within the group-wise interleaved bit groups.
