Abstract: 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.
