Performance Simulation of the IEEE 802.16d Physical Layer

旨在对基于IEEE 802.16d技术的物理层OFDM进行系统仿真和性能分析,文章首先对IEEE 802.16d标准的发射机和接收机工作过程进行了详细描述,分析了该系统物理层的基本原理,在此基础上,基于LabVIEW系统仿真软件,构建了一个典型的W irelessMAN-OFDM系统仿真模型与框架,给出了系统性能的基本仿真结论。该系统仿真模型与框架可以用于对W irelessMAN-OFDM系统的深入研究和探讨,这对W iMAX系统的优化设计、缩短系统的开发周期具有十分重要的意义。

This paper aims to make system simulation and performance analyzsis of the physical OFDM based on IEEE 802.16d technology. It describes the procedure of the transmitter and receiver, analyses the basic principle of the system physical layer, and then＇, the LabVIEW system simulation software is used to design a typical Wireless- MAN- OFDM system simulation model and framework. The system simulation model and framework may help to deeply research and discuss the WirelessMAN - OFDM system and be very important for the WiMAX system to optimize the design and shorten the system development cycle.
