“…The first one does not decrease system throughput because it produces neither data packet collision nor empty slots. Therefore, in order to reduce the loss in throughput, we can increase the detection threshold θ (14), which reduces the error rate of the second type.…”

“…This problem may be ascribed to two reasons. First, contention resolution is traditionally considered in the MAC layer only [1], [14], whereas collided signals are processed in the physical (PHY) layer. Second, many schemes originate from those developed decades ago when advanced signal processing techniques were not available [10].…”

Traditional methods for resolving random access contentions usually work in the MAC layer only without considering the rich information of the physical layer signal. Most of them suffer from low efficiency and lack of priority scheduling capability. This paper shows that advanced signal processing techniques can be used for complete contention resolution, i.e., packet collisions can be either avoided or exploited. This task can be realized by designing jointly the physical layer signal separation algorithm and the MAC layer smart scheduling protocols. An innovative property is that packet priority, and thus QoS, can be guaranteed along with high transmission efficiency in random access wireless networks with unknown multiple users. 1243 0-7803-7802-4/03/$17.00
