基于DFT-SOFDM的MIMO技术研究

Research into Multiple Input Multiple Output technique based on DFT-SOFDM

DFT-SOFDM(DFT Spread-OFDM)是3GPP上行链路传输技术,研究了它与多输入、多输出(M IMO)技术相结合的方案,并对这种M IMO系统的信道估计导频设计进行了仿真。得到的基于空时分组码的M IMO技术方案是一种提高上行链路容量的有效方案,并仿真研究了导频量设计对系统性能的影响。

DFT - SOFDM （ DFT Spread - OFDM） is a transfer technique of 3 GPP uplink. This paper studies the scheme of its connection with Multiple Input Multiple Output（MIMO） technique, simulates channel estimation pilot frequency design of this MIMO system, arrives at that the scheme based on space time block coding is an effective scheme for DFT -SOFDM uplink system and makes simulation research into the effect of pilot frequency quantity on the character of this system.
