8. A method for wireless communication, comprising:
encoding an input sequence c={c0, c1, c2, . . . , cK−1} by using a low density parity check (LDPC) matrix to obtain an output sequence d={d0, d1, d2, . . . , dN−1}, wherein K and N are integers greater than 0;
wherein the output sequence d comprises K0 bits in the input sequence c and parity bits in a parity sequence w, K0 is an integer, and 0<K0≤K; and
wherein the parity sequence w and the input sequence c satisfy

OG Complex Work Unit Math
wherein H is the (LDPC) matrix, cT=[c0, c1, c2, . . . , cK−1]T is a transposed vector of a vector including bits in the input sequence c, wT=[w0, w1, w2, . . . , wN−K0−1]T is a transposed vector of a vector including bits in the parity sequence w, and 0T is a column vector, and values of all elements of the column vector 0T are 0.
