基于MATLAB/Simulink的2ASK传输系统设计与分析

摘要

Based on modulation and demodulation theory in communication,we successfully design a 2ASK transmission system based on MATLAB/Simulink platform. Debugging and testing show that the waveforms of the system are consistent with the theoretical analysis and error-free code transmission can be achieved;the symbol error rate is rising with the increase of noise,which indicates that the system design is effective and reasonable. It is worth reference for related research and the improvement of such system,and also provides a new way for system design and experimental teaching.%基于MATLAB/Simulink仿真软件,根据通信系统调制与解调原理完成2ASK传输系统设计,对系统进行测试验证,观察发现系统各点波形与理论分析一致,噪声较小时能够实现无误码传输,分析发现随着噪声的增大误码率也逐渐增大,表明系统设计合理有效.2ASK传输系统设计对相关研究和系统改善有一定借鉴意义,同时也为系统设计以及实验教学提供一种新方法.
