Illustrating PNC Using Rectangular Pulses

摘要

Physical-layer network coding (PNC) opens up a whole new research area because it innovatively proposes implementing upper-layer functions (i.e., network coding) at the physical layer. Study shows that PNC can achieve 100% throughput improvement compared with the traditional scheme. This paper aims at providing an entry-level tutorial that can help readers quickly and thoroughly understand the basic idea of PNC. In this paper, we first overview basic assumptions, bitwise XOR operation, network coding (NC), and then illustrate the decoding process and the performance of PNC using the example of rectangular pulses.
