Polar coding for the wiretap broadcast channel with multiple messages
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference lecture
Open AccessA polar coding scheme is proposed for the Wiretap Broadcast Channel with two legitimate receivers and one eaves-dropper. We consider a model in which the transmitter wishes to to reliably send different confidential and ... -
Stochastic geometry analysis and design of wireless powered MTC networks
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessMachine-type-communications (MTC) are being crucial in the development of next generation mobile networks. Given that MTC devices are usually battery constrained, wireless power transfer (WPT) and energy harvesting (EH) ... -
Autoencoders for health improvement by compressing the set of patient features
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference lecture
Restricted access - publisher's policyA challenge to solve when analyzing multimorbidity patterns in elderly people is the management of a high number of characteristics associated with each patient. The main variables to study multimorbidity are diseases, ... -
Array-geometry invariant signaling for MISO feedforward opportunistic communications
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessThe impact of antenna array geometry on scenario- aware invariant signaling is studied in the context of feedforward opportunistic communications. Invariance plays an elemental role to guarantee the detectability in ... -
Energy allocation for short-packet massive multiple access with two-iteration successive decoding
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessAn optimum energy allocation for massive user networks operating under iterative successive interference cancellation (I-SIC) is derived in this work. We analyze an uplink setting where a large network of cost-effective ... -
Source enumeration via Toeplitz matrix completion
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessThis paper addresses the problem of source enumeration by an array of sensors in the presence of noise whose spatial covariance structure is a diagonal matrix with possibly different variances, referred to non-iid noise ... -
A novel formulation of independence detection based on the sample characteristic function
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference lecture
Open AccessA novel independence test for continuous random sequences is proposed in this paper. The test is based on seeking for coherence in a particular fixed-dimension feature space based on a uniform sampling of the sample ... -
Squared-loss mutual information via high-dimension coherence matrix estimation
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessSquared-loss mutual information (SMI) is a surro- gate of Shannon mutual information that is more advantageous for estimation. On the other hand, the coherence matrix of a pair of random vectors, a power-normalized version ... -
Interference mitigation under degrees-of-freedom sensing uncertainties in opportunistic transmission
(2019)
Conference report
Open AccessInter-system interference may limit the performance of co-existing systems in dense heterogeneous wireless networks. Context-aware waveform design can profitably overcome this limitation. However, the latter substantially ... -
A non-linear channel code for covert communications
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Restricted access - publisher's policyThis paper presents an explicit channel code design for covert communications in the Binary Symmetric Channel. The proposed architecture is composed of the serial concatenation of a linear code and a graph-based non-linear ... -
Joint energy and rate allocation for successive interference cancellation in the finite blocklength regime
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference lecture
Open AccessThis work addresses the optimization of the network spectral efficiency (SE) under successive interference cancellation (SIC) at a given blocklength n. We adopt a proof-of-concept satellite scenario where network users can ... -
Decentralized shaping for pilot generation and detection in opportunistic communications
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessThe uncoordinated design of pulse shaping filters for opportunistic communications is addressed. We show that under degrees-of-freedom sensing uncertainties the waveform design problem can be cast as a minimum-norm ...
