Abstract

This paper describes the problems caused by the phase noise in the development of micro- and millimeterwave range crosscorrelation type wideband channel sounders. The procedure to estimate the phase noise and its effect on the dynamic range of the impulse response measurement is given. It can be seen that the effect of the phase noise becomes more significant as the measurement frequency increases. With typical components a dynamic range of 35 dB was estimated at 60 GHz.

基于直接序列的信道测深器中的相位噪声
介绍了在研制微毫米波互关型宽带信道测深仪过程中,相位噪声所引起的问题。给出了相位噪声及其对脉冲响应测量动态范围影响的估计方法。可以看出,随着测量频率的增加,相位噪声的影响越来越明显。对于典型组件,在60 GHz时估计动态范围为35 dB。
