Abstract:
Lost packets, either due to errors or collisions, are usually discarded and need to be retransmitted, leading to performance losses. In this paper we compare the performance of two different approaches to cope with lost packets. One alternative is a multi-packet detection approach able to separate up to Qmax mobile terminals transmitting in one slot. The other alternative is a low-complexity soft combining ARQ scheme (Automatic Repeat reQuest) employed in a TDMA (Time Division Multiple Access) architecture. This paper evaluates the uplink non-saturated packet delay and goodput for a Poisson traffic generator. Our analytical results are validated by simulation using joint PHY (physical layer) and MAC (Medium Access Control) behavior.
