中频数字化接收机系统建模与仿真

Modeling and Simulation of IF Digital Receiver

对于中频数字化接收机,通常采用Matlab的可视化工具Simulink进行建模和仿真,功能模块都是调用Matlab的子函数来实现,因此系统模型与硬件实现会有一定的差异,导致仿真结果与实际性能不能完全一致。介绍采用Matlab语言编程实现中频数字化接收机的建模和仿真,使系统模型尽可能与真实的硬件平台相一致,仿真结果更接近实际情况。

Conventional IF digital receiver uses the Simulink module in Matlab to create the modeling and simulation, the function module is realized by subfunction of Matlab,so the difference is existed between system models and hardware implementation,and the simulation results are in consistent with the fact. How to create the modeling and simulation by using Matlab programming language, make the system modeling according with the hardware as soon as possible are introduced, and the simulation results reflect the factual capability much more.
