TRANSMITTING APPARATUS AND INTERLEAVING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18151219 titled 'TRANSMITTING APPARATUS AND INTERLEAVING METHOD THEREOF
Simplified Explanation
The patent application describes a transmitting apparatus that utilizes low-density parity check (LDPC) encoding to generate a codeword, which is then interleaved and mapped onto a modulation symbol.
- The encoder in the transmitting apparatus performs LDPC encoding based on a parity check matrix.
- The interleaver rearranges the LDPC codeword to improve its error correction capabilities.
- The modulator maps the interleaved LDPC codeword onto a modulation symbol.
- A specific bit group within the LDPC codeword is selected, and a predetermined bit from that group is mapped onto a specific bit of the modulation symbol.
Potential Applications
This technology has potential applications in various fields, including:
- Wireless communication systems
- Satellite communication systems
- Digital broadcasting systems
Problems Solved
The technology addresses the following problems:
- Error correction in data transmission
- Efficient encoding and decoding of LDPC codewords
- Interleaving to improve error correction capabilities
Benefits
The benefits of this technology include:
- Improved error correction capabilities in data transmission
- Efficient LDPC encoding and decoding
- Enhanced performance in wireless communication systems
Original Abstract Submitted
A transmitting apparatus is provided. The transmitting apparatus includes: an encoder configured to generate a low-density parity check (LDPC) codeword by LDPC encoding based on a parity check matrix; an interleaver configured to interleave the LDPC codeword; and a modulator configured to map the interleaved LDPC codeword onto a modulation symbol, wherein the modulator is further configured to map a bit included in a predetermined bit group from among a plurality of bit groups constituting the LDPC codeword onto a predetermined bit of the modulation symbol.
