摘　　要：在长期演进(LTE)无线通信系统中,用户终端与基站建立无线通信链路的前提是进行小区搜索,以获取物理小区标识(PCI)。首先,介绍小区搜索系统的组成与信号处理流程,并提出一种PCI验证方法;然后,给出PCI验证方法的现场可编程门阵列实现方案,并采用Verilog HDL硬件描述语言实现;最后,进行电路仿真实验。实验结果表明,该方法设计合理,能够过滤虚假PCI,保证小区搜索系统的可靠性。In the long term evolution(LTE)wireless communication system,the precondition for the user terminal to establish a wireless communication link with the base station is to conduct cell search to obtain the physical cell identifier(PCI).Firstly,the composition and signal processing flow of the cell search system are introduced,and a PCI verification method is proposed;Then,the field programmable gate array implementation scheme of PCI verification method is given and implemented by Verilog HDL hardware description language;Finally,the circuit simulation experiment is carried out.The experimental results show that the design of this method is reasonable,and it can filter false PCI and ensure the reliability of the cell search system.
