1. method of operating transmitter, this transmitter is according to current sign collection s=(s 0..., s K-1) generation parity check bit p=(p 0..., p M-1), this method comprises the steps:

  • Receive said current sign collection s=(s 0..., s K-1);

    Utilize matrix H to confirm said parity check bit;

    AndSend said parity check bit and said current sign collection;

    Wherein, H is via model matrix H BmBasis matrix H bExpansion, Wherein, H bComprise m bIndividual row, section H B1With section H B2, and H B2Comprise and have weight w h

    =3 row h b, Wherein, arrange h bAnd H B1In 1, make to form H BmMiddle one or more groups of going, the H in each group BmCapablely do not intersect, Wherein, said basis matrix H bEach row can be by displacement so that per two in succession capable do not intersect.
