Disclosed in the present application is an encoding method, an apparatus, a communication device and a communication system. The method comprises: encoding an input bit sequence using a Low Density Parity Check LDPC matrix; the LDPC matrix is obtained on the basis of a spreading factor Z and a basis matrix; the basis matrix includes 0 to 4th lines and 0 to 26th columns in one of the matrixes shown in Fig.3b-1 to Fig.3b-8; or the basis matrix includes 0 to 4th lines and a part of 0 to 26th columns in one of the matrixes shown in Fig.3b-1 to Fig.3b-8. According to the encoding method, the apparatus, the communication device and the communication system in the present application, channel encoding demands can be satisfied.
