Modulation Feature Enhancement with a Multi-Stage Attention Network for Underwater Acoustic Target Recognition
Jiaping Yu, Shefeng Yan, Linlin Mao +2
Underwater acoustic target recognition is critical for maritime applications, yet it faces challenges arising from the complex and diverse nature of ship-radiated noise. To address…
Distributed Detection and Bandwidth Allocation with Hybrid Quantized and Full-Precision Observations over Multiplicative Fading Channels
Linlin Mao, Zeping Sui, Michail Matthaiou +1
A hybrid detector that fuses both quantized and full-precision observations is proposed for weak signal detection under additive and multiplicative Gaussian noise. We first derive…
Ambiguity-Free Broadband DOA Estimation Relying on Parameterized Time-Frequency Transform
Wei Wang, Shefeng Yan, Linlin Mao +2
An ambiguity-free direction-of-arrival (DOA) estimation scheme is proposed for sparse uniform linear arrays under low signal-to-noise ratios (SNRs) and non-stationary broadband sig…
Multi-bit Distributed Detection of Sparse Stochastic Signals over Error-Prone Reporting Channels
Linlin Mao, Shefeng Yan, Zeping Sui +1
We consider a distributed detection problem within a wireless sensor network (WSN), where a substantial number of sensors cooperate to detect the existence of sparse stochastic sig…
