Eigendecomposition-Based Partial FFT Demodulation for Differential OFDM in Underwater Acoustic Communications
Jing Han, Lingling Zhang, Qunfei Zhang +1
Differential orthogonal frequency division multiplexing (OFDM) is practically attractive for underwater acoustic communications since it has the potential to obviate channel estima…
Sparse Bayesian Learning for DOA Estimation in Heteroscedastic Noise
Peter Gerstoft, Santosh Nannuru, Christoph F. Mecklenbräuker +1
The paper considers direction of arrival (DOA) estimation from long-term observations in a noisy environment. In such an environment the noise source might evolve, causing the stat…
The Dual Graph Shift Operator: Identifying the Support of the Frequency Domain
Geert Leus, Santiago Segarra, Alejandro Ribeiro +1
Contemporary data is often supported by an irregular structure, which can be conveniently captured by a graph. Accounting for this graph support is crucial to analyze the data, lea…
Consistent Sensor, Relay, and Link Selection in Wireless Sensor Networks
Rocio Arroyo-Valles, Andrea Simonetto, Geert Leus
In wireless sensor networks, where energy is scarce, it is inefficient to have all nodes active because they consume a non-negligible amount of battery. In this paper we consider t…
