Estimation of the K-Factor for Temporal Fading From Single-Snapshot Wideband Measurements

open access: yesIEEE Transactions on Vehicular Technology, 2019
The Ricean K-factor is the ratio of the power of the deterministic multipath component (MPC) and the power of all other stochastic MPCs. The classical moment-based method has been successfully used to estimate the K-factor from time series measurements ...

Degrees of Freedom of Generic Block-Fading MIMO Channels without A Priori Channel State Information

open access: yes, 2014
We studynthe high-SNR capacity of generic MIMO Rayleigh block-fading channels in the noncoherent setting where neither transmitter nor receiver has a priori channel state information but both are aware of the channel statistics.

HOPS 383: An Outbursting Class 0 Protostar in Orion [PDF]

open access: yes, 2015
We report the dramatic mid-infrared brightening between 2004 and 2006 of HOPS 383, a deeply embedded protostar adjacent to NGC 1977 in Orion. By 2008, the source became a factor of 35 brighter at 24 microns with a brightness increase also apparent at 4.5

Adaptive Estimation of Multiple Fading Factors for GPS/INS Integrated Navigation Systems [PDF]

open access: yesSensors, 2017
The Kalman filter has been widely applied in the field of dynamic navigation and positioning. However, its performance will be degraded in the presence of significant model errors and uncertain interferences. In the literature, the fading filter was proposed to control the influences of the model errors, and the H-infinity filter can be adopted to ...

On performance analysis for optimum combining of DF relaying with fast-fading multiple correlated CCIs, correlated source-relay, and thermal noise

open access: yesEURASIP Journal on Wireless Communications and Networking, 2019
This paper analyzes the outage probability (OP) and the average symbol error rate (SER) of decode-and-forward (DF) relaying. The paper derives closed-form expressions for the OP and the average SER with optimum combining (OC) considering fast-fading ...

Power Scaling of Uplink Massive MIMO Systems with Arbitrary-Rank Channel Means

open access: yes, 2014
This paper investigates the uplink achievable rates of massive multiple-input multiple-output (MIMO) antenna systems in Ricean fading channels, using maximal-ratio combining (MRC) and zero-forcing (ZF) receivers, assuming perfect and imperfect channel ...

On Capacity of the Dirty Paper Channel with Fading Dirt in the Strong Fading Regime

open access: yes, 2014
The classical writing on dirty paper capacity result establishes that full interference pre-cancellation can be attained in Gelfand-Pinsker problem with additive state and additive white Gaussian noise.

UAV-Aided Wireless Power Transfer and Data Collection in Rician Fading

open access: yesIEEE Journal on Selected Areas in Communications, 2021
A UAV-aided wireless power transfer and data collection network is studied, where it is assumed that when the harvested energy at the sensor node (SN) cannot surpass its circuit activation threshold or the received data rate at UAV falls below a minimal ...

Rooftop and indoor reception with transmit diversity applied to DVB-T networks: A long term measurement campaign [PDF]

open access: yes, 2009
Although transmit Delay Diversity (DD) can provide a gain in indoor and other Non Line of Sight situations (NLOS), it can introduce degradation in rooftop reception. In fact, when the Ricean K factor of the channel is significantly high (e.g.
