Bit-interleaved coded modulation using low density parity check (ldpc) codes

Claims a method for signal of the clusters of marker bit the scheme of. According to one example embodiment transmitter uses the low density parity check ldpc code structure parity check matrix produce the encoded signal. Sender comprises a decoder configured to the input information is converted into a plurality of bit aggregation represented by the code word. Transmitting device comprises which is used to one bit the collection orderly such as interleaving mapped to the higher order of the cluster quadrature phase shift keying qpsk 8 psk 16 apsk amplitude phase shift keying 32 apsk and so on the logic according to mapping the output is more advanced cluster in the corresponding to said a plurality of bit aggregation of the symbols.
