Abstract
The importance of multiuser detection for CDMA-based ad hoc network is addressed in this paper. Conventionally, the terminal in CDMA-based ad hoc network uses matched filter to receive packets, so the performance (e.g., 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 and Log-distance path loss radio propagation model, the throughput of ad hoc network with multiuser detection is studied. Simulation results show that multiuser detection can remarkably enlarge the throughput of ad hoc network.
