Low-Complexity Channel Estimation for Internet of Vehicles AFDM Communications With Sparse Bayesian Learning
Xiangxiang Li, Haiyan Wang, Yao Ge +4
Affine frequency division multiplexing (AFDM) has been considered as a promising waveform to enable high-reliable connectivity in the internet of vehicles. However, accurate channe…
Message Feedback Interference Cancellation Aided UAMP Iterative Detector for OTFS Systems
Xiangxiang Li, Haiyan Wang, Yao Ge +2
The designing of efficient signal detectors is important and yet challenge for orthogonal time frequency space (OTFS) systems in high-mobility scenarios. In this letter, we develop…
Delay-Doppler Reversal for OTFS System in Doubly-selective Fading Channels
Xiangxiang Li, Haiyan Wang, Yao Ge +2
The recent proposed orthogonal time frequency space (OTFS) modulation shows signifcant advantages than conventional orthogonal frequency division multiplexing (OFDM) for high mobil…
Time Reversal based MAC for Multi-Hop Underwater Acoustic Networks
Ruiqin Zhao, Hao Long, Octavia A. Dobre +3
Constrained-energy underwater acoustic nodes are typically connected via a multi-hop underwater acoustic network (MHUAN) to cover a broad marine region. Recently, protocols for eff…
Reliable IoT Storage: Minimizing Bandwidth Use in Storage Without Newcomer Nodes
Xiaobo Zhao, Daniel E. Lucani, Xiaohong Shen +1
This letter characterizes the optimal policies for bandwidth use and storage for the problem of distributed storage in Internet of Things (IoT) scenarios, where lost nodes cannot b…
