Research and design for a ranging code generator of BeiDou II

For common ranging code generation issue of BeiDou Ⅱ Navigation Satellite System,an improved implementation principle of ranging code generator is presented,and then a specific implementation scheme is given.Compared with traditional ranging code generator,the design scheme adopted the methods of different satellite encoding setting different initial values to improve the convenience of the circuit use.In the algorithms parallel processing methods is used to improve the code generation rate.The simulation results of the circuit proved that the design can receive the same encoding results with the traditional code generation.
