Backscatter Device-aided Integrated Sensing and Communication: A Pareto Optimization Framework
Passive backscatter tags used as ambient reflectors can improve both sensing and communication in an OFDM-based ISAC system, and a block-coordinate-descent algorithm can trace the resulting sensing-rate Pareto trade-off.
