LOW DENSITY PARITY CHECK ENCODER HAVING LENGTH OF 64800 AND CODE RATE OF 7/15, AND LOW DENSITY PARITY CHECK ENCODING METHOD USING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18419393 titled 'LOW DENSITY PARITY CHECK ENCODER HAVING LENGTH OF 64800 AND CODE RATE OF 7/15, AND LOW DENSITY PARITY CHECK ENCODING METHOD USING THE SAME
Simplified Explanation
The abstract describes a patent application for a low density parity check (LDPC) encoder, decoder, and encoding method. The encoder includes memories and a processor to generate LDPC codewords based on information bits and a parity check matrix.
- LDPC encoder, decoder, and encoding method disclosed:
* The encoder includes first and second memories, and a processor. * The first memory stores an LDPC codeword with specific length and code rate. * The second memory is initialized to 0. * The processor generates LDPC codewords by accumulating data from the second memory using a parity check matrix.
Potential Applications
The technology can be applied in:
- Telecommunications
- Data storage
- Satellite communications
Problems Solved
- Error correction in data transmission
- Efficient encoding and decoding of data
- Reliable communication over noisy channels
Benefits
- Improved data reliability
- Enhanced error correction capabilities
- Higher quality communication signals
Potential Commercial Applications
- Telecommunication equipment manufacturers
- Data storage companies
- Satellite communication providers
Possible Prior Art
One example of prior art in LDPC encoding and decoding is the work of Robert G. Gallager in the 1960s, who first introduced LDPC codes.
Unanswered Questions
How does the LDPC encoder handle different code rates?
The abstract mentions a specific code rate of 7/15, but it does not explain how the encoder can adapt to different code rates.
What is the computational complexity of the LDPC encoding method?
The abstract does not provide information on the computational resources required to perform LDPC encoding, which could be crucial for practical applications.
Original Abstract Submitted
A low density parity check (LDPC) encoder, an LDPC decoder, and an LDPC encoding method are disclosed. The LDPC encoder includes first memory, second memory, and a processor. The first memory stores an LDPC codeword having a length of 64800 and a code rate of 7/15. The second memory is initialized to 0. The processor generates the LDPC codeword corresponding to information bits by performing accumulation with respect to the second memory using a sequence corresponding to a parity check matrix (PCM).
