Physical-layer network coding (pnc) channel decoding at the relay is of key importance for good performance in pnc systems however, pnc channel decoders c. In this thesis, a two-way relay (twr) channel technique is adopted to increase system spectral efficiency, which in turn boosts the network throughput this is achieved by using a physical layer network coding (pnc) technique, where network coding (nc) is applied at the physical layer it takes advantage. Abstract: this paper considers applying physical-layer network coding (pnc) to orthogonal frequency division multiplexing (ofdm) modulated mobile ad-hoc networks (manets) to resolve the outstanding issue of short contact time between nodes due to their mobility ideally, pnc enables data exchange.
Can be proposed this thesis investigates a set of processing schemes tailored to the network coding at the physical layer with various compromises between per- formance and complexity we consider a two-way relay channel (twrc), a typical communication system in cooperative networks, where two. Physical-layer network coding (pnc) is a new approach to harnessing interference in wireless net- works rather this dissertation studies a family of the state-of-the-art pnc schemes called compute-and-forward (c&f) this thesis is the result of the support, help, and advice that i have received from an amazing group.
In this thesis, we study the data rate optimization for twr channel with physical- layer network coding (pnc) first, we investigate a general twr channel with flexible durations of uplink and downlink the results obtained can be applied in more general channel model in the process of optimizing weighted sum-rate of twr.
