摘要

UE（用户终端）专用参考信号[1]在LTE-A（改进的长期演进）系统中用于PDSCH（物理下行链路共享信道）解调。文章首先研究了UE专用参考信号的生成方式

然后根据公式设计了程序实现流程;之后采用TI公司TMS320C6455系列的DSP（数字信号处理器）进行软件编程

生成UE专用参考信号;最后给出了该方案的具体实现流程图及执行效率。经过验证

该方案能够满足LTE-A系统的性能需求。

Abstract

UE-specific reference signals are used for the demodulation of Physical Downlink Shared Channel（PDSCH）measurements in Long Term Evolution Advance（LTE-A）systems.This paper first investigates the various formulas for the generation of the UE-specific reference signals.Then it designs the flow of program realization and generates the UE-specific reference signals by software programming using TI（Texas Instruments）corporationTMS320C6455DSP.Finally

it gives the specific implementing flow chart for this scheme and the execution efficiency.The verification results show that this scheme satisfies the performance requirements of LTE-A systems.
