资料介绍

最小频移键控是一种特殊的连续相位调制技术,广泛应用于数字通信系统中。根据基于正交调制方式实现MSK信号的基本原理,利用Multisim电路仿真软件设计包括原始信号产生、差分编码、基带加权信号产生、乘法电路等模块的MSK调制仿真电路。在设计过程中综合应用数字电路、模拟电路、通信原理、通信电路等课程中学习到的理论知识,给出各模块的实现原理和仿真电路,最后绘出输入输出信号波形并分析仿真结果,验证电路实现与理论知识的一致性。

Minimum shift keying (MSK) is a special continuous phase modulation technology, which is widely used in digital communication systems. The basic principle to realize MSK signal based on quadrature modulation scheme is introduced. The modulation simulation circuit of MSK including the modules of original signal generation, differential coding, baseband weighted signal generation and multiplication circuit was designed by using circuit simulation software Multisim. In the design process, the theoretical knowledge learned from some related courses such as digital circuit, analog circuit, communication principle, communication circuit, is applied comprehensively. The realization principles and simulation circuits of various modules a...
