抑制载波单边带 suppressed carrier single sideband
- 振幅调制分为4种方式:AM(普通调幅)、DSB(抑制载波双边带调幅)、SSB(单边带调幅)、VSB(残留边带调幅)。
Amplitude modulation is divided into 4 ways: am (amplitude), DSB (bilateral with carrier suppression modulation), SSB (single sideband modulation), VSB (VSB). - 其思路是将信号先通过单边带调制,将较低频率调制到需要的频率范围;然后采用对基带信号的数字预补偿方法来抑制镜像频率和载波泄漏,从而达到应用的目的。
Then we perform digital pre-compensation method, which can be used in the processing of base band signal to reject image frequency and protect carrier leak to meet the application purpose.
