DECODING SYSTEM, AND TRANSMITTING/RECEIVING DEVICE THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17941549 titled 'DECODING SYSTEM, AND TRANSMITTING/RECEIVING DEVICE THEREOF
Simplified Explanation
The patent application describes a decoding system consisting of a receiving device and a transmitting device. The receiving device includes several components such as a demapper, deparser, codeword loader, decoder controller, and a low-density parity check (LDPC) decoder.
- The demapper converts received data into a log likelihood ratio (LLR) signal.
- The deparser rearranges the LLR signal by deparsing it into orthogonal frequency division multiplex (OFDM) symbols.
- The codeword loader outputs the rearranged LLR signal in units of codewords.
- The decoder controller controls the maximum iteration number and the number of decoders to be enabled based on the state of the received data.
- The LDPC decoder repeatedly decodes the LLR signal in units of codewords, as many times as the controlled maximum iteration number, according to the controlled number of decoders.
Potential applications of this technology:
- Wireless communication systems
- Digital broadcasting systems
- Satellite communication systems
- Mobile communication systems
Problems solved by this technology:
- Efficient decoding of received data
- Improved error correction capabilities
- Optimization of decoding process based on the state of received data
Benefits of this technology:
- Enhanced data transmission reliability
- Increased data throughput
- Improved overall system performance
Original Abstract Submitted
Provided are a decoding system including a receiving device and a transmitting device. The receiving device comprises a demapper configured to convert received data into a log likelihood ratio (LLR) signal and output the LLR signal, a deparser configured to rearrange the LLR signal by deparsing the LLR signal into orthogonal frequency division multiplex (OFDM) symbols, a codeword loader configured to output the rearranged LLR signal in units of codewords, a decoder controller configured to control a maximum iteration number and the number of decoders to be enabled according to a state of the received data and a low-density parity check (LDPC) decoder configured to repeatedly decode the LLR signal in units of codewords, according to the controlled number of decoders, as many times as the controlled maximum iteration number, wherein the received data comprises real data and a packet extension corresponding to a pre-FEC (forward error correction) padding factor.
