Interference-Constrained IRS-aided SWIPT [PDF]
2021 IEEE 22nd International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2021 We consider a spectrum underlay setup comprised by a primary and a secondary multiple-input single-output (MISO) broadcast system. The latter performs simultaneous wireless information and power transfer (SWIPT) with the aid of an intelligent reflecting surface (IRS).

Tone-Index Multisine Modulation for SWIPT [PDF]
IEEE Signal Processing Letters, 2019 We propose a new simultaneous wireless information and power transfer (SWIPT) technique that embeds information bits in the tone-index of multisine waveforms. By varying the number of subcarriers of the transmitted bandwidth-constrained multisine signal, the proposed scheme enables efficient radio-frequency energy harvesting and low-complexity ...
