调制技术在无线电发射机中的的应用极为重要，需要发射的低频信号都要经过调制才能发送传输。因此调制是改变高频载波信号特征来传递频信息的过程，是移动通信系统中提高通信质量的一项关键技术，通过对信号的调制，可以使信号特性与信道特性相匹配。
Modulation technique in the application of the transmitter is very important, need to launch the low-frequency signals can be sent through the modulation. Therefore modulation is changing frequency carrier signal transmission frequency characteristics of the process, is the information of mobile communication system to improve the quality of a key technology, based on the modulation signal, can make the signal characteristics and channel characteristic matching.
Modulation technique in radio transmitter applications in the very important and need to launch low-frequency modulation signal to go through in order to send transmission. Therefore is to change the modulation characteristics of high-frequency carrier signal to transmit the frequency information of the process, the mobile communications system to improve the quality of a key communications technologies, through the modulation of the signal can be the signal characteristics and to match the channel characteristics.
