FIELD: radio communications; data transfer or error-affected data retransmission.
SUBSTANCE: transmitter generates S sub-codes Ci (i = 0, 1, 2, …, S - 1) from data stream of physical layer burst using quasi-additional turbo codes; it primarily sends first sub-code C0 and then sequentially transfers next sub-codes each time upon reception of retransmit request for original transmission or for preceding retransmission. Upon receiving retransmit request for last sub-code CS - 1 transmitter sends first sub-code C0 and then sequentially transfers next sub-codes each time upon receiving retransmit request.
EFFECT: enhanced throughput capacity.
