Most medium access controltechniques assume that a collision means total packetloss. However, we will show that this assumption isnot always true, and we investigate how to leveragethis fact.We first investigate fundamentally what happens whena collision occurs. We begin by deriving a physicallayer algorithm that can identify which bits havebeen corrupted by collision. This algorithmaccurately locates all collision induced errors whenthe channel signal to noise ratio is high enough forreliable communication. By leveraging this algorithm,we can produce a wide range of benefits. For example,by providing collisionlocation information, we can enhance forward errorcorrecting codes so that they may effectivelycompletely remove the collision, saving a packet thatwould otherwise be discarded.…
