本文首先叙述了基于TETRA标准的数字集群系统基站控制单元工作原理和设计思想,在介绍其关键技术的基础上,提出了用VHDL语言及CPLD技术设计基站控制单元的研究思路。仿真结果验证了CPLD技术在数字集群系统基站控制单元中应用的可行性。
This paper first describes the working principle and design idea of base station control unit of digital trunking system based on TETRA standard. Based on the introduction of its key technologies, this paper proposes a research idea of designing base station control unit by using VHDL language and CPLD technology. The simulation results verify the feasibility of CPLD technology in the digital trunking system base station control unit.
