| 摘 要： | 随着第三代移动通信技术的应用,正交频分复用技术即将成为第四代移动通信的核心技术。在构建正交频分复用系统时必须考虑信号同步问题。针对信号传输误码率的问题,结合导频序列的相关特性,提出一种基于导频序列的正交频分复用系统的同步模型,并在矩阵实验室的可视化仿真平台上实现了系统模型的仿真与分析。仿真测试表明,该系统能对数据同步实现较高增益,并进行有效传输。

| Abstract: | With the application of 3G mobile communication technology,orthogonal frequency division multiplexing would soon become the core of 4G mobile communication technology.In constructing orthogonal frequency division multiplexing system,the signal synchronization must be considered.For signal transmission bit-error rates,combining with the relevant characteristics of pilot frequency sequence,this paper proposes an orthogonal frequency division multiplexing system model based on pilot frequency sequence.Also,simulation and analysis of the system model on Matlab Simulink platform is done.The simulation and analysis indicates that the system could achieve fairly high gain in signal synchronization and effective transmission. |
