| Abstract: | A code division multiple access(CDMA)coding for the nodes′location information of underwater sensor network node is presented.The basic idea of CDMA encoding are introduced.By CPLD,sub-frequency circuit,m-sequence sine wave generated circuit,as well as the ASK modulation circuit is realized.Tests show that the designed circuit is simple,stable and multiple-node location information can be transferred conveniently and effectively. |
