AI Technical Summary
Technical Problem
When existing LDPC codes require longer code lengths to support high throughput, the shift value table cannot meet the demand for more shift values, resulting in unstable parity check matrix performance.
Method used
By promoting each element in the LDPC base matrix to a 2x2 matrix and designing translation values for multiple regions to satisfy specific relationships, such as linear or nonlinear functions, the stability of the loop properties of the parity check matrix and the good code distance are ensured.
Benefits of technology
It achieves a longer code length, making it suitable for higher throughput scenarios, improving decoding performance and parallelism, and reducing decoding latency.
