Throughput of mobile ad hoc network(MANET)is limited by collision avoidance.In CDMA-based MANET, this limitation can be overcome by multiuser detection(MUD)because conventional colliding packets can be detached and detected by MUD so that multi-packet reception(MPR)is possible.This paper introduces the principles of MUD algorithm for MANET,and proposes an adaptive blind MUD algorithm.A special medium access control(MAC)protocol is designed to make MANET more efficient.This is achieved by sending more packets to a destination simultaneously.The proposed MUD algorithm and MAC protocol allow CDMA-based MANET to support MPR.Simulations show a remarkable improvement in the throughput performance of MANET.
