UAV Relay Flight Path Planning in the Presence of Jamming Signal
The flight path of the unmanned aerial vehicle (UAV) relay can significantly affect the performance of the wireless relay communication system. In this paper, we investigate the optimization of the UAV flight path in a wireless relay communication system,

Increase of Carrier-to-Noise Ratio in GPS Receivers Caused by Continuous-Wave Interference [PDF]
The increased use of personal private devices (PPDs) is drawing greater attention to the effects of continuous-wave interference (CWI) on the performance of global positioning system (GPS) receivers.

An Improved Sub-Array Adaptive Beamforming Technique Based on Multiple Sources of Errors
In this paper, a new robust adaptive beamforming method is proposed in order to improve the robustness against steering vector (SV) mismatches that arise from multiple types of array errors.

Adaptive processing with signal contaminated training samples [PDF]
We consider the adaptive beamforming or adaptive detection problem in the case of signal contaminated training samples, i.e., when the latter may contain a signal-like component.

Performance analysis of beamformers using generalized loading of the covariance matrix in the presence of random steering vector errors [PDF]
Robust adaptive beamforming is a key issue in array applications where there exist uncertainties about the steering vector of interest. Diagonal loading is one of the most popular techniques to improve robustness.

Adaptive detection of distributed targets in compound-Gaussian noise without secondary data: A Bayesian approach [PDF]
In this paper, we deal with the problem of adaptive detection of distributed targets embedded in colored noise modeled in terms of a compound-Gaussian process and without assuming that a set of secondary data is available.The covariance matrices of the ...

Cognitive GFDM Full-Duplex Radios With RF Impairments and ACI Constraints
We investigate the problem of sum-rate maximization of a secondary link of full-duplex generalized frequency division multiplexing (GFDM) radios operating over a spectrum hole, which is surrounded by two active primary adjacent channels.

In mobile communication networks, the handover procedure enables a continuous communication service for users on the move. However, handovers, handover failures, and ping‐pong handovers increase the signalling load in the network, resulting in the use of network resources and a reduction of the system throughput.
