Abstract
A block-code-based structure that allows cross-packet coding of data using a sliding window. In this structure, each transmitted packet contains both information symbols and parity symbols generated by the information in previous packets. This code structure allows a receiver to recover lost packets without additional transmissions. If enough packets have been lost so that the receiver cannot recover one or more of them, new parity symbols can be generated and transmitted as additional packets. The parity symbols in these additional packets may be used by multiple receivers. Thus, the sliding window block code reduces retransmission overhead, particularly for multicast applications. Furthermore, the sliding window structure does not produce an encoding delay between the arrival of data and its transmission and reduces the decoding delay between the loss of a packet and its recovery.
