摘要

正交频分复用(OFDM)技术作为第四代移动通信的关键技术，以其较高的频谱效率和抗多径能力成为当前高速数据传输系统的主流。在OFDM仿真系统中，用于信号流处理的时钟程序是正确解析整个系统的关键之一。本文利用SCICOS图形仿真平台对OFDM传输系统进行仿真，重点分析了时钟同步和数据流处理的关键问题，并给出了解决方案。

Analysis and resolution of key issues in OFDM system simulation

As the Key technology of Fourth generation Mobile, Orthogonal frequency division multiplexing (OFDM) has become a mainstream in the current high-speed data transmission system with the higher spectral efficiency and the ability to resist multi-path make the technology. In OFDM simulation system, clock program for the signal stream processing is one of the sticking point of parsing the entire system correctly. In this paper, with OFDM transmission system simulation in SCICOS graphical simulation platform, we focus on analyzing the Key issues of clock synchronization and data stream processing, and ultimately give the solutions.
