5 Claims

1. A transmission method performed by a transmitter, the transmission method comprising:

generating, by a coding circuit of the transmitter, a codeword according to repeat accumulate quasi-cyclic low-density parity-check coding such that the codeword consists of N cyclic blocks, the N cyclic blocks each consist of Q bits, each of N and Q is a positive integer, and a code rate of the codeword is 7/15;

reordering, by an interleaving circuit of the transmitter, the N cyclic blocks;

mapping, by a mapping circuit of the transmitter, bits in the codeword onto constellation points of a non-uniform 4096 QAM scheme to generate mapped bits after the N cyclic blocks are reordered; and

generating, by a signaling circuit of the transmitter, a transmission signal by performing orthogonal frequency-division multiplexing (OFDM) modulation on the mapped bits, wherein

the N cyclic blocks are reordered according to Table 1 which is associated with the code rate, and

in the Table 1, the j-th block of Group-wise Interleaver Output indicates the index of the cyclic block after the N cyclic blocks are reordered, and the it(j)-th block of Group-wise Interleaver Input indicates the index of the cyclic block before the N cyclic blocks are reordered
