Abstract:
1. A Method for transmitting data comprising a plurality of data bits, the method comprising the steps: the data is mapped to a plurality of modulation symbols, each modulation symbol comprising at least one more significant bit and at least one less significant bit; at least one parity bit is generated for the plurality of data bits; a codeword is generated, wherein the codeword comprising the plurality of data bits and the at least one parity bit generated; the plurality of data bits are mapped to more significant bits of the plurality of modulation symbols and the at least one parity bit is mapped to at least one less significant bit of the plurality of modulation symbols, wherein the codeword is arranged in the form of a block of bits, the block of bits comprises at least two rows of bits, and the codeword is written to the block of bits in the row direction; and the codeword where pi,j is the element of the permutation matrix in the ith row and the jth column, θ=0, 1, . . . , N−1 and μ=N/s×(θ mod s)+floor(θ/s), θ=0, 1, . . . , N−1, wherein the codeword {tilde over (c)} is of length N, and the block comprises s rows.
