| 摘 要： | 提出4G无线通信系统的仿真方法。针对无线通信系统的特点,将建模分为5个方面:业务需求建模、无线链路建模、业务处理机制建模、保证无线链路可靠性机制建模及统计量建模。按照此方法搭建采用MIMO-OFDM技术的WiMAX系统级仿真平台,研究了建模真实性与效率间的关系。仿真结果证明了平台的正确性,并表明WiMAX在多小区组网模式轻负载情况下能提供可接受的时延性能。

| Abstract: | System level simulation methodology is proposed for the 4G wireless system.According to wireless communication system characteristics,modeling is divided into five parts:service requirement modeling,wireless link modeling,service processing mechanism modeling,reliability guarantee mechanism modeling and statistic modeling.MIMO-OFDM based WiMAX system level simulation platform is constructed follow this method.The tradeoff between similarity and efficiency is discussed.Simulation results verify platform's validity and show that WiMAX system can provide acceptable delay performance under multi cell environment and low system load. |
