Abstract

Packetized random access based on code division multiple access (CDMA) is considered. Our primary aim is to assess the impact of (uncoded) multi-user (MU) detectors on the performance of CDMA with slotted ALOHA. The impact of respective multiple packet reception capability for the matched filter and MMSE detector on delay/throughput improvements (vis-a-vis narrowband slotted ALOHA that are collision limited) is investigated
