摘要

参考信号在LTE（Long Term Evolution

长期演进）中具有重要的作用

主要用于接收端提取信息并用于信道估计、均衡等.根据LTE系统相关的物理层协议规范，结合现场可编程逻辑门阵列（FieldProgrammable Gate Array，FPGA）设计技术，给出了解调参考信号生成的设计流程图.并采用ALTERA公司Cyclone III系列的FPGA芯片实现了解调参考信号的生成.仿真结果表明，基于FPGA的解调参考信号生成实现方案能够达到LTE相关协议规定的要求.

Abstract

The reference signal plays an important role in LTE（Long Term Evolution）

which is mainly used to extract information for channel estimation

equalization and etc.. According to the LTE physical layer protocol specification

the paper presents the design flow chart of the generation of the demodulation reference signal with the field programmable gate array (FPGA) design techniques by using the FPGA chip of ALTERA-s Cyclone III series. Simulation results show that the FPGAbased demodulation reference signal generation program can achieve the requirements of LTErelated specifications.
