PACE: Redundancy Engineering in RLNC for Low-Latency Communication

IEEE Access, 2017
Random linear network coding (RLNC) is attractive for data transfer as well as data storage and retrieval in complex and unreliable settings. The existing systematic RLNC approach first sends all source symbols in a generation without encoding followed ...

Reflective Metasurface With Steered OAM Beams for THz Communications

IEEE Access, 2023
The abundant spectrum resources and low beam divergence of the terahertz (THz) band, can be combined with the orthogonal propagation property of orbital angular momentum (OAM) beams to multi-fold the capacity of wireless communication systems.

SpaRec: Sparse Systematic RLNC Recoding in Multi-Hop Networks

IEEE Access, 2021
Sparse Random Linear Network Coding (RLNC) reduces the computational complexity of the RLNC decoding through a low density of the non-zero coding coefficients, which can be achieved through sending uncoded (systematic) packets.
