FIELD: communication systems; coding in communication systems using turbo codes.
SUBSTANCE: proposed improved sequential redundancy augmentation on turbo-coding basis and automatic request for re-transmission includes first stage 102 of punching data stream during first transmission affording set of non-punched sections of first lattice. Next stage 104 involves punching data stream for second transmission affording set of non-punched sections of second lattice. Still next stage 106 includes combination of non-adjacent and non-punched sections of first and second lattices in decoder affording composite pattern with uniformly distributed sections. In this way unified punching scheme is created.
EFFECT: reduced rate of frame error occurrence due to sequentially augmented redundancy.
