摘要

在信道容量增加的有线系统中,电视接收机的本地振荡器可能会在相邻用户之间造成干扰。为了避免干扰,信道偏移技术在电缆系统中有效,并且正在实施最大接收器本地振荡器泄漏的标准。基于两个用户模型和信道偏移的消除,已经进行了一项研究,以评估本地振荡器干扰发生的最大总体概率。

Occurrence of Local Oscillator Interference on Cable Television Systems
In cable systems with augmented channel capacity, the local oscillators of TV receivers can cause interference between neighbouring subscribers. To avoid the interference, channel off-setting techniques are in effect in cable systems and standards for maximum receiver local oscillator leakage are being implemented. A study, based on a two-subscriber model and on the removal of channel off-setting, has been undertaken to evaluate the maximum overall probability of occurrence of local oscillator interference.
