Abstract

The importance of multiuser detection for CDMA-based mobile ad hoc networks is addressed in this paper. Conventionally, terminals in CDMA-based ad hoc networks use matched filters to receive packets, so the throughput of the network suffers from multi-access interference (MAI). Different from above scheme, in this paper, each terminal of the ad hoc network is equipped with an adaptive blind linear multiuser detector, so the ability of MAI-resistance is gained. Based on fully-connected network model, the throughput of ad hoc network with multiuser detection is studied in link-level. Theoretic analysis and simulation results show that multiuser detection can remarkably increase the throughput of ad hoc networks
