Influence of local oscillator phase noise on noise figure of wideband receiver
Dianzi Jishu Yingyong, 2020 Based on the analysis of the influence of wide-band local oscillator with different phase noise on the received noise figure of the wideband receiver, a wideband mixer is used to actually test to obtain the phase noise of the mixer IF signal, through the

Unified Constellation Design Using Projection Over QAM: Concept and Examples
IEEE Open Journal of the Communications Society, 2023 Beyond fifth generation (B5G) / sixth generation (6G) wireless systems require full utilization of all spectrums. However, hardware devices operating in the high-frequency bands bring a series of non-ideal behaviors, including nonlinear distortion caused

Joint Effect of Heterogeneous Intrinsic Noise Sources on Instability of MEMS Resonators [PDF]
Electronics, 2015 This article's focus is on the numerical estimation of the overall instability of microelectromechanical-system-based (MEMS) resonators, caused by intrinsic noise mechanisms that are different in nature (electrical, mechanical or chemical). Heterogeneous
