一种北斗二号测距码生成器的设计

针对北斗二号卫星导航系统中普通测距码的生成问题,提出了一种改进的测距码生成的实现原理,并给出具体实现方案。与传统的测距码生成器相比,本设计采用不同卫星编码设置不同初值的方法,提高了电路使用的便利性,还在算法上采用并行处理的方法,提高了码生成速率。对电路功能的仿真证明其可以得到与传统码生成器相同的编码结果。

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 im- prove 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.
