正交频分复用(OFDM)是第四代移动通信的核心技术,它是实现多媒体业务发展的基础.讨论了如何利用Simulink进行OFDM系统仿真,并给出了具体的仿真模型.利用仿真模型得到OFDM差错性能分析结果,通过对结果的分析,提出了改善性能的方法. (Orthogonal frequency division multiplexing (OFDM) is the core of the fourth generation mobile communication technology, it is the basis for the development of multimedia services. Discusses how to use Simulink for OFDM system simulation, and given the specific simulation model. Using the simulation model OFDM Error Performance Analysis of the results obtained through analysis of the results, proposed to improve performance.)

主要实现的是系统在分布式管理下，在一定可靠性的条件下，系统的稳定性的判断。通过得到的计算值来估算系统的可靠性。(Mainly achieved in distributed under the management of the system, the reliability of certain conditions, the stability of the system of judgments. Obtained by calculating the value of to estimate the reliability of the system.)
