Abstract
An information processing method and apparatus. The method comprises: acquiring a first bit sequence; performing low-density parity check (LDPC) encoding on the first bit sequence on the basis of a first shift value matrix and a first lifting factor to obtain a second bit sequence, wherein a first shift value of a first region in the first shift value matrix is obtained on the basis of a second shift value in a second shift value matrix, the first lifting factor is greater than a first value, and the first value and the first lifting factor belong to the same lifting factor set; and outputting the second bit sequence. In the method, the first lifting factor is greater than the first value, so that a larger-scale check matrix can be obtained; and LDPC encoding is performed on the basis of the check matrix, so that a longer code length and a higher throughput can be supported, thereby improving the performance of an LDPC code.
