AI Technical Summary
There is room for improvement in the basis matrix of existing LDPC codes in terms of coding performance and decoding complexity, especially in how to improve the basis matrix in communication systems to improve the reliability of channel transmission and reduce decoding complexity.
By improving the base matrix, specifically by dividing it into a first row region and a second row region, and by changing the edge relationships to make the last row of the base matrix orthogonal to the other rows, the reading order of non-zero elements is kept constant, thereby improving encoding and decoding performance.
It improves the encoding and decoding performance of LDPC codes, reduces communication latency and decoding complexity, and enhances the reliability and overall performance of communication systems.
