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.)

说明：  针对小流域设计洪水计算中，采用推理公式求解洪峰流量Qm及汇流时间τ的方法繁琐，查算精度较低等问题，提出用牛顿迭代法求解，该方法较原图解试算法收敛快，迭代次数少，计算速度快，精度可靠。计算实例表明，用简单迭代法与牛顿迭代法计算设计洪峰流量，其结果与图解试算法完全一致。()
