Controlling Peak-to-Average Power Ratio in Orthogonal Frequency Division Multiplexing System
A major drawback of Orthogonal Frequency Division Multiplexing at the transmitter side is the high peak-to-average power ratio (PAPR) of the signal. Conventional solutions for this problem are to use a linear amplifier ( or to back-off the operating ...

Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers
ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

Non-Orthogonal Multicarrier Waveform for Radar With Communications Systems: 24 GHz GFDM RadCom
In this paper, we propose the usage of Generalized Frequency Division Multiplexing (GFDM), a non-orthogonal multicarrier waveform for radar. We presented a novel method that cancels the effect of interference caused by the non-orthogonality of GFDM ...
