Abstract
An automatic retransmission system offering good latency and overhead characteristics combined with programmable tradeoffs among overhead, latency, and error performance. ARQ (Automatic Repeat reQuest) blocks present at both ends of a link coordinate to automatically attempt to re-send data if that data was not received properly the first time it was sent. Re-transmission from the transmitter (transmitter) is requested by the receiver (Receiver) via a highly reliable 'Repeat Request' (RR) mechanism. This RR scheme carries sufficient information back to the transmitter for it to determine which previous transmissions need to be re-sent.
