An improved full-duplex retransmission technique
Current concepts in computer telecommunication are surveyed. Error detection with retransmission is shown to be the best method in general to achieve near error-free data transmission over common carrier channels. A new version is proposed by the authors which is specifically designed for full-duplex links. The superiority of this technique is demonstrated by a simulation program which compares the proposed partial retransmission scheme with an ideal block retransmission method with degraded line conditions.
