详细说明: Little Known Characteristics of Phase Noise 为你揭开相位噪声的神秘面纱 INTRODUCTION There is a wealth of information available on the topic of phase noise, its characteristics1, how it can be measured2, and how it affects system performance3. It is well known that phase noise in oscillators and clocks becomes one of the limiting degradations in modern radio systems. However, most of the traditional analyses concentrate on degradations to sine wave signals in single carrier radio systems. The effects of phase noise on multicarrier receivers, wideband systems, or digital radios are very rarely discussed. This application note will address some of the rarely discussed issues related to phase noise in sampled data systems. It will focus primarily on multicarrier radios, wideband signals, and under- sampled radio architectures. ...展开收缩
