Rotationally Invariant Coded Modulation for Physical Layer Network Coding in Two-way Relay Fading Channel
This paper investigates a novel coded modulation scheme for Physical Layer Network Coding (PLNC) in the Two-Way Relay (TWR) fading channel. Using a fully-adaptive adaptive soft demodulator and Independent Decoding Levels, the proposed scheme can eliminate the effect of fading on the TWR Channel. To reduce system complexity at the relay, we also provide a low-complexity scheme with a series of f...
متن کاملMobile Lattice-Coded Physical-Layer Network Coding With Practical Channel Alignment
Physical-layer network coding (PNC) is a communications paradigm that exploits overlapped transmissions to boost the throughput of wireless relay networks. A high point of PNC research was a theoretical proof that PNC that makes use of nested lattice codes could approach the information-theoretic capacity of a two-way relay network (TWRN), where two end nodes communicate via a relay node. The c...
متن کاملPhysical-Layer Network Coding with M-QAM Modulation
The denoise-and-forward (DNF) method of physical-layer network coding (PNC) is a promising approach for wireless relaying networks. Most related work in the literature focuses on low-level modulations, such as binary phase-shift keying (BPSK) or quadrature phase-shift keying (QPSK). In this paper, we consider DNF-based PNC with high-level modulations, specifically the M-ary quadrature amplitude...
متن کاملNoncoherent LDPC-Coded Physical-Layer Network Coding using Multitone FSK
A noncoherent two-way relaying system is developed using physical-layer network coding for improved throughput over conventional relaying in a fading channel. Energyefficient noncoherent operation is achieved using multitone frequency shift keying (FSK). A novel soft-output demodulator is developed for the relay, and corresponding achievable exchange rates are found for Rayleigh fading and AWGN...
متن کاملPhysical-layer network coding in coherent optical OFDM systems.
We present the first experimental demonstration and characterization of the application of optical physical-layer network coding in coherent optical OFDM systems. It combines two optical OFDM frames to share the same link so as to enhance system throughput, while individual OFDM frames can be recovered with digital signal processing at the destined node.
