A 2.4GHz 830pJ/bit duty-cycled wake-up receiver with −82dBm sensitivity for crystal-less wireless sensor nodes [PDF]

, 2010
A 65 nm CMOS 2.4 GHz wake-up receiver operating with low-accuracy frequency references has been realized. Robustness to frequency inaccuracy is achieved by employing non-coherent energy detection, broadband-IF heterodyne architecture and impulse-radio ...

Distributed Target Detection with Coherent Fusion in Tracking Based on Phase Prediction

Remote Sensing
In distributed radar, a coherent system often gains attention for its higher detection potential in contrast to its non-coherent counterpart. However, even for a distributed coherent radar, it is difficult to coherently accumulate local observations in ...

Efficient Optimal Joint Channel Estimation and Data Detection for Massive MIMO Systems

, 2016
In this paper, we propose an efficient optimal joint channel estimation and data detection algorithm for massive MIMO wireless systems. Our algorithm is optimal in terms of the generalized likelihood ratio test (GLRT).

Multiple symbol soft-output non-coherent detection of serial concatenated CPM

Tongxin xuebao, 2012
A non-coherent detection algorithm for CPM was proposed.Several sequential symbols were used as the observation window to calculate the prior probability for codeword in CPM soft demodulation process,and the more observation symbols were used,the better ...

Optical synthesis of large-amplitude squeezed coherent-state superpositions with minimal resources

, 2015
We propose and experimentally realize a novel versatile protocol that allows the quantum state engineering of heralded optical coherent-state superpositions. This scheme relies on a two-mode squeezed state, linear mixing and a $n$-photon detection. It is

Out-sphere decoder for non-coherent ML SIMO detection and its expected complexity [PDF]

, 2007
In multi-antenna communication systems, channel information is often not known at the receiver. To fully exploit the bandwidth resources of the system and ensure the practical feasibility of the receiver, the channel parameters are often estimated ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
