==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).
