Abstract
An error control system retransmits a portion of information if an error occurs on the portion in transmitting the information. The retransmission is carried out in the steps of dividing information into information blocks each composed of one or a plurality of bits; transmitting the information blocks from a transmitter to a receiver in one of a plurality of first transmission areas, the first transmission areas being arranged at predetermined time intervals on a time axis, each of the first transmission areas having a first predetermined time length; judging whether or not errors have occurred on the information blocks in transmitting them; transmitting requests for retransmitting information blocks which have been judged to have errors, from the receiver to the transmitter; and retransmitting the information blocks for which the retransmission requests have been made, from the transmitter to the receiver in one of a plurality of second transmission areas, the second transmission areas being arranged alternately with the first transmission areas on the time axis, each of the second transmission areas having a second predetermined time length.
