The invention provides a recursive encoding method of spatially-coupled low-density parity check codes. The method includes the following steps that: a check basis matrix Hi<~> of (dv,dc and L) spatially-coupled low-density parity check codes (SC-LDPC) is constructed, and each line of the check basis matrix Hi<~> is a d'c*(d'vms+d'v-1)-dimensional matrix including continuous d'vms sub matrixes, and the first d'vms elements of the first line to the (d'c-d'v+1)-th line in the check basis matrix Hi<~> are the sub matrixes, and the (n-d'c+d'v)-th element to the (n-d'c+d'v+d'vms-1)-th element of the n-th line in the check basis matrix Hi<~> are the sub matrixes; and the check matrix H[0,L-1] of the SC-LDPCs is obtained through the check basis matrix Hi<~>; and the check matrix H[0,L-1] is utilized to perform recursive encoding. With the recursive encoding method of the spatially-coupled low-density parity check codes provided by the invention adopted, recursive encoding of the (dv,dc and L) SC-LDPCs can be realized when dc/dv are non-integers.
