| This paper introduces a project based on code division multiplexed that is used to realize four El channels's wireless transportation.After briefly introducing the whole structure of the device of transportation,this paper introduces mainly implemention of the hardware .Futhermore,the discussion concerning the selection of principles in code acquisition and the threshold setting of code acquisition on continous pilot in the receiving unit is given .At the same time,the methods about how to design the parameters of DLL is introduced in this paper .In addtion,how to solve the actual problems in debugging the hardware is also provided. Finally,the improving proposals about the project is put forward. |
