摘要
基于一个语音信号处理系统,采用MATLAB/SIMULINK来对系统进行可视化建模,动态仿真。主要通信过程为抽样、量化、编码、调制解调、缩短卷积码加交织的差错控制等,并给出了几种调制解调的主要特性。详细分析其模型建立,参数设置,为实际系统的建立提供了参考和依据。
Based on a speech signal processing system, the Matlab/Simulink is used for visual modeling and dynamic simulation of the system. The main process of communication is sampling, quantifying, coding, modulation, the adding of reduced convolution code with interlacing, such as error control, and the main characteristics of several modulations are given. The article analyzes the model establishment and parameter setting so as to provide references and ground for the practical system.
