摘　　要：Pattern time delay shift coding(PDS) scheme is introduced and combined with spread spectrum tech-nique called SS-PDS for short which is power-saving and competent for long-range underwater acoustic networks.Single-element virtual time reversal mirror(VTRM) is presented in this paper and validated by the lake trial results.Employing single-element VTRM in multiuser communication system based on SS-PDS can separate different users' information simultaneously at master node as indicated in the simulation results.Pattern time delay shift coding （PDS） scheme is introduced and combined with spread spectrum tech- nique called SS-PDS for short which is power-saving and competent for long-range underwater acous- tic networks.
