On robustness of physical layer network coding to pollution attack

Physical Layer Network Coding

A main distinguishing feature of a wireless network compared with a wired network is its broadcast nature, in which the signal transmitted by a node may reach several other nodes, and a node may receive signals from several other nodes simultaneously. Rather than a blessing, this feature is treated more as an interference-inducing nuisance in most wireless networks today (e.g., IEEE 802.11). Th...

Investigation on Gaussian Waveforms to Improve Robustness in Physical Layer Network Coding

In this paper, two-way relaying networks using physical layer network coding under practical constraints are considered. In the multiple access phase, both users transmit their messages simultaneously on the same resources. At the relay a superposition of both massages is received containing the influence of the channel as well as the impact of Carrier Frequency Offsets (CFOs) and Timing Offset...

Algebraic Approach to Physical-Layer Network Coding

The problem of designing physical-layer network coding (PNC) schemes via nested lattices is considered. Building on the compute-and-forward (C&F) relaying strategy of Nazer and Gastpar, who demonstrated its asymptotic gain using information-theoretic tools, an algebraic approach is taken to show its potential in practical, non-asymptotic, settings. A general framework is developed for studying ...
