With the rapid development of the Internet of Things (IoT), simultaneous wireless information and power transfer (SWIPT) has recently drawn significant attention in both academia and the industry. In this talk, Dr Chan introduced the physical-layer network coding with SWIPT (PNC-SWIPT) scheme. Unlike conventional interference mitigation schemes in wireless communications, the PNC-SWIPT scheme does not minimise the interfering signals at the receivers. The PNC-SWIPT scheme cancels out the undesired messages over a finite field by PNC for information decoding. It significantly preserves the interfering signals, which are beneficial energy sources for energy harvesting.
