Abstract:
1. A communication system in which an automatic retransmission control for a partial number bit string is executed, the communication system comprising: a transmitter configured to encode a number bit string to be transferred into the partial number bit string as a part of the number bit string and to transmit the encoded partial number bit string; and a receiver configured to receive the partial number bit string and to decode the partial bit number string into the number bit string while shifting an interval that is a range of a partial number bit string decodable into the number bit string by using the received partial number bit string and a reference value shared by the transmitter and the receiver, wherein the transmitter includes an encoding processor configured to perform the encoding for a future-direction interval associated with a partial number bit string to be transmitted after a newest partial number bit string while taking, as a reference, the newest partial number bit string that is the partial number bit string which the receiver has succeeded in receiving normally, and the receiver includes a decoding processor configured to perform the decoding for a past-direction interval associated with a partial number bit string transmitted at least prior to the newest partial number bit string while taking the newest partial number bit string as the reference.
