摘要
研究MC(蒙特卡罗)仿真法和QA(准解析)仿真法的基本思想。为了验证这两种方法在通信系统仿真中的适用性与一致性,根据仿真原理,提出了相应的应用分析,首先建立二进制通信系统模型,然后利用Simulink软件,在相同的运行条件下,通过设置不同的信噪比,对模型的误码率进行了仿真。仿真结果表明这两种方法都能获得同样精确的仿真结果,而准解析法由于其解析的特性,仅需仿真整个系统中的非线性部分,因而相比于蒙特卡罗法所需的仿真运行时间更短,效率更高。
Introduce the basic theory of MC（Monte - Carlo） method and QA（Quasi - analytical） method.In order to validate the applicability？ and coherence of these two methods on the simulation of communication system,according to their simulation theories,the corresponding application thoughts are brought forward,and a communication system model of binary sequence is built,and different signal noise ratios are set,and the system＇ s error rate under the same running condition is simulated by Simulink software.The results show that both methods can acquire the same accuracy simulation results.Due to the analytical character of Quasi - analytical method,this method only needs to simulate the non - linear？ part of the whole system.Compare to Monte - Carlo method,Quasi - analytical method has less simulation time and higher efficiency.
