The author's main work is the development of the lo (localoscillator) in DTV transmitter, it is one of the important research projects planned by Shanghai Mingzhu Company.
In modern radar and communication system, phase noise of localoscillator (lo) becomes a vital factor of system performance.
在现代雷达和通讯系统中，本振相位噪声越来越成为决定系统性能的关键因素。
