摘要
导频设计和信道估计是OFDM系统中重要的研究课题。本文主要介绍了TD-SCDMA在LTE长期演进中的导频设计原则和方案,分别对下行、上行导频的频域和时域结构进行了仿真分析。并对LS和简化的MMSE算法的性能进行了仿真比较和分析。
Pilot design and channel estimation are important research task in OFDM system. This paper introduces pilot design principle and scheme for TD-SCDMA LTE. Frequency domain and time domain structure of downlink and uplink have been analyzed and simulation results have also been given. From the simulation, the performance of LS and simplified MMSE channel estimation arithmetic has been compared and brief analyzed
