摘要

考虑了建立基于单波段跳频调制器的有线电视头端站的可能性。相对于现有的DALVI或CRYPTON置乱系统,本文讨论了基于载波的跳频置乱。在帧脉冲期间,通过发送端和接收端同时进行载波跳频来实现置乱。实验结果证实了利用载波跳频技术实现电视群信号置乱的可能性。

Group TV signal transmission with carrier frequency hopping
A possibility of setting up a single-band frequency-hopping modulator-based cable TV head-end station is considered. As opposed to the available DALVI or CRYPTON scrambling systems, frequency-hopping carrier-based scrambling is discussed. The scrambling is achieved by the simultaneous carrier frequency hopping at transmitter and receiver during the frame pulse. Experimental results have confirmed the possibility of providing TV group signal scrambling by means of the carrier frequency hopping.
