摘要： A low density parity check code transmission method and device, for use in improving the anti-burst-error capability of a low density parity check code. The method provided by the present application comprises: an interleaver changes the sequence of bit streams of a low density parity check code according to a preset rule, and outputs to a modulator the low density parity check code the sequence of bit streams of which is changed; the modulator modulates the low density parity check code the sequence of bit streams of which is changed and then sends the modulated low density parity check code to a receive end by using a channel.

摘要： An encoding method and apparatus, and a computer storage medium, wherein same are used to improve the LDPC encoding performance, and are thus suitable for 5G systems. The encoding method comprises: determining a base graph of a low density parity check code (LDPC) matrix, and constructing a cyclic coefficient index matrix; determining a sub-cyclic matrix according to the cyclic coefficient index matrix; and carrying out LDPC encoding according to the sub-cyclic matrix and the base graph.
