CHANNEL ENCODING METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17954425 titled 'CHANNEL ENCODING METHOD AND APPARATUS
Simplified Explanation
The abstract describes a method and apparatus for channel encoding. Here are the key points:
- The method involves obtaining information bits to be encoded.
- The information bits and CRC (Cyclic Redundancy Check) bits are mapped to a first bit sequence using an interleaving sequence.
- The interleaving sequence can be obtained from a pre-stored table or based on a maximum-length interleaving sequence.
- The length of the interleaving sequence is denoted as Kmax.
- The first bit sequence is then encoded.
- This method reduces encoding delay and allows for early stop capability in decoding, resulting in reduced decoding delay.
Potential applications of this technology:
- This channel encoding method can be used in various communication systems, such as wireless communication, satellite communication, and digital broadcasting.
- It can be applied in data transmission protocols, error correction techniques, and data storage systems.
Problems solved by this technology:
- The method reduces encoding delay, which is beneficial in real-time communication systems where low latency is crucial.
- The early stop capability in decoding helps to reduce decoding delay, improving overall system efficiency.
Benefits of this technology:
- Reduced encoding delay allows for faster data transmission and improved real-time communication performance.
- The early stop capability in decoding reduces decoding delay, leading to more efficient data processing.
- The method provides a reliable channel encoding technique, enhancing the accuracy and integrity of transmitted data.
Original Abstract Submitted
A channel encoding method and apparatus. The method includes: obtaining A to-be-encoded information bits; mapping the A to-be-encoded information bits and L CRC bits to a first bit sequence based on an interleaving sequence, where the L CRC bits are obtained based on the A to-be-encoded information bits and a CRC polynomial, the interleaving sequence is obtained from a prestored interleaving sequence table or is obtained based on a maximum-length interleaving sequence, A+L is less than or equal to Kmax, and Kmax is a length of the maximum-length interleaving sequence; and encoding the first bit sequence. In this way, not only an encoding delay can be reduced, but also decoding has an early stop capability, so that decoding can end in advance, thereby reducing a decoding delay.
