调制与解调中在电子通信系统中具有重要的作用,而且信号的传送需要调制与解调作为手段才可以实现,调制的含义指的是通过信号来影响信号的参量,最终形成的信号就是调制的信号。而解调与调制这是两个相互正反面,解调的反面就是调制,通过解调后信号可以转变成初始的信号,PAM是脉冲幅度调制的简称,这是一个通过信号来决定周期脉冲序列的过程。本文主要讨论的是基于Matlab的PAM的调制与解调的仿真,仿真部分的实现选择的仿真软件是Simulink。
Modulation and demodulation in the electronic communication system has an important role, but also the signal transmission needs modulation and demodulation as a means to achieve, the meaning of modulation refers to the signal through the signal to influence the parameters of the final signal is modulated signal of. The demodulation and modulation This is the two positive and negative, demodulation is the reverse modulation, through the demodulated signal can be transformed into the initial signal, PAM is the abbreviation of pulse amplitude modulation, which is a signal to determine the periodic pulse sequence the process of. This article mainly discusses the modulation and demodulation simulation of PAM based on Matlab, and the simulation software of the simulation part is Simulink.
