Channel Analysis And Implementation Based On Inductive Coupled Transmission Technology

As an important element in any country's strategy for future interests providing capacious view and near-unlimited resources,the ocean gives a huge impact on such aspects like homeland security,energy crisis,global environment.For even decades,the influence triggered by oceanic information and its collection on both military and civilian use has been stepping up to a hard-to-ignore level.Inductive Coupling,applied to underwater data transmission,and its integrated system as an equipment to acquire and deliver information could be easily fitted into fields and sorts of platforms.This technology,which based on electromagnetic induction to achieve no-contact transferring has great edges under deep sea circumstances,is a vanguard one in this particular subject and has received a great deal of attention.Setbacks,however,exist for multi-complex situations(environment,costs and etc)and signal's amplitude decay and phase deviation will lead to distortion and instability of that signal.Our research aimed at the low speed problem on existing practice by conducting on channel serials of experiments and analysis.First of all,the mathematical model has been built up standing on from cables,magnetic rings,medium,to even whole links.Another point,the hallmarks of signal out which are refined could be used to stimulate the transmission channel and to analysis the effects burdened on frequency,phase,delay,decay,distortion by channel's defects and noise in order that the crucial key to fast and highly reliable workstation would be worked out.What's more,the optimal modeming way has been hammered out via comparing the bit error rate.At last,this algorithm for modeming has been transplanted to FPGA platform using Verilog HDL language.In this paper,our particular model for channel analysis could be applied to many other related areas,which provides great instructive significance.
