| 摘 要： | 本文研究2ASK信号的设计方法和计算机仿真,通过使用LabVIEW语言对2ASK传输系统进行设计及仿真.此次仿真包括调制和解调两个模块,在调制模块中,将输入序列与载波相乘产生2ASK信号,然后将调制出的信号加入高斯白噪声模拟真实信道的情况,在送入低通滤波器滤波后采用相干解调的方式实现2ASK的解调,形成所要的波形.并通过改变输入序列的输入值来得到波形.

| Abstract: | The paper studies a design method of ASK signal and simulation results with computer.The 2ASK transmission system is designed and simulated by using LabVIEW language.The simulation includes the modulation and demodulation of the two modules in the modulation module.The basic idea is that the waveform is obtained with the input sequence multiplied by carrier.The modulated signal is then added to the Gauss white noise to simulate the real channel condition. After being fed into the low pass filter,the demodulation of 2ASK is realized by means of coherent demodulation.Waveform is obtained by changing the input value of the input sequence. |
