近来国内外无线电通信中利用单边带技术日趋广泛,因此就单边带技术有关单边带信号包络的某些问题如:(1)包络反馈在单边带中的应用与在一般调幅中应用的区别;(2)在用包络消去恢复法以产生大功率单边带信号应注意频率响应及包络与载波的相对相位,否则将增加不需要的发射;(3)在基础信号(原始多路信号)加以削幅是否能降低单边带信号的峰值等,略述所见以就正于读者.
Recently, the use of single-sideband technology in radio communications at home and abroad is becoming more and more widespread. Therefore, some issues about single-sideband signal envelope in single-sideband technology are as follows: (1) The application of envelope feedback in single sideband ; (2) the frequency response and the relative phase of the envelope and the carrier should be noted in generating the high-power single-sideband signal with the envelope cancellation recovery method; otherwise, the unwanted emission will be increased; (3) (The original multi-channel signal) to be able to reduce the single sideband signal peak amplitude, etc., outlined in the reader just to see.
