Abstract :
A novel viewpoint for the collision resolution problem is introduced in this paper for wireless slotted random access networks. This viewpoint is based on signal separation principles borrowed from signal processing problems. The received collided packets are not discarded in this approach but are exploited to extract each individual user packet information. In particular, if k users collide in a given time slot, they repeat their transmission for a total of k times, so that k copies of the collided packets are received. Then, the receiver has to resolve a k×k source mixing problem, and separate each individual user. The proposed method does not introduce throughput penalties since it requires only k slots to transmit k colliding packets. Performance issues are studied in the paper, related to the implementation of the collision detection algorithm
