A Physical Layer Scheme in Two-Way Relay Networks with Soft Network Coding
The previous schemes are introduced, including traditional network coding (NC) scheme, physical-layer network coding (PNC) scheme, soft network coding (SNC) scheme and pseudo physical-layer network coding (PPNC) scheme. As an improved scheme of PNC, PPNC does not need synchronization mechanism, however its BER performance gets worse due to the hard decision applied on the relay node. The new pr...
متن کاملSer-minimization Relay Selection for Two-way Relay Channels with Physical Layer Network Coding
This paper explores the relay selection scheme for two-way relay channels with physical layer network coding (PNC), where two end nodes exchange information via a selected relay node with the minimal symbol error rate (SER) performance among multiple candidate relay nodes. To reduce the computational complexity, we also propose a suboptimal minimal SER-based relay selection. The end-to-end SER ...
متن کاملSER - Based Relay Selection for Two - Way Relaying with Physical Layer Network Coding
© 2013 ETRI Journal, Volume 35, Number 2, April 2013 To enhance the symbol error rate (SER) performance of the two-way relay channels with physical layer network coding, this letter proposes a relay selection scheme, in which the relay with the maximal minimum distance between different points in its constellation among all relays is selected to assist two-way transmissions. We give the closed-...
متن کاملEigen-Direction Alignment Based Physical-Layer Network Coding for MIMO Two-Way Relay Channels
In this paper, we propose a novel communication strategy which incorporates physical-layer network coding (PNC) into multiple-input multiple output (MIMO) two-way relay channels (TWRCs). At the heart of the proposed scheme lies a new key technique referred to as eigen-direction alignment (EDA) precoding. The EDA precoding efficiently aligns the two-user’s eigen-modes into the same directions. B...
متن کاملEnergy-efficient resource allocation for OFDMA-based two-way relay channel with physical-layer network coding
Physical-layer network coding (PNC) is a novel cooperative technique for two-way relay channel (TRC), where two users exchange information via intermediate relay node(s). On the other hand, the issue of green communications to reduce energy consumption has recently started to arouse much attention. This article studies the energyefficient resource allocation problem for orthogonal frequency div...
