摘要
研究了目前通信领域中广泛采用的QPSK及QDPSK调制,并利用Matlab这一强大的软件,通过M函数的编写,进行软件仿真,得出了相应的波形与频谱.该结果可以弥补硬件设备中由于干扰引起的误差,且较之以往采用的imulink工具箱进行的同类处理,具有参数设置少、修改方便灵活、函数易于保存,方便其他程序调用、操作更为快捷直观等优点.
This paper introduces the QPSK＆QDPSK modulation which are widely used in current wireless communication, it also simulates the process through M-file programming with the powerful software-MATLAB, and shows the results of corresponding waveform and spectrum. This toothed can eliminate errors from hardware devices, and when compared with simulink toolbox used previously, it has the advantages of less parameters, facilitate modification, easy preservation, and more efficient operation.
