摘要
首先将所设计的通信系统拆分成语音输入、抽样、量化、编解码以及调制解调等模块;然后通过Matlab编程进行模块设计功能实现;最后通过GUI编程实现各个通信系统模块的调用和链接,从而最终实现语音信号数字化传输系统通信系统的仿真。通过基于GUI界面设计和仿真结果表明,仿真模型能够反映话音信号数字带通系统的动态工作情况,具有较强的演示性、可视性和实用性;同时对于利用软件无线电技术构建无线通信具有十分重要的参考意义。
The designed communication system is first divided into several modules： voice input,sampling and quantitation,encoder/decoder,modulation/demodulation,etc.Then the functional modules of the system are implemented with in MATLAB programming.Finally the calls of and links between modules are realized through the GUI programming,and the simulation on various functions of the digital audio signal transmission communication system is done.GUI design and simulation indicate that the simulation model could reflect dynamic operation of the digital band-pass system,and has strong demonstration,visualization and practice.Also the proposed method is effective and of great significance to the wireless communication by software radio.
