What happened
Collection of recent wireless/ISAC research highlights affecting sensing, positioning, and multi-antenna communications. Key findings: carrier-phase ranging estimators become biased under deterministic multipath (threatening positioning integrity); digital leakage suppression is fundamentally limited by quantization noise (reducing self-interference cancellation and increasing residual transmit leakage); hardware impairments and ADC resolution tradeoffs significantly affect parametric channel estimation and sensing/communication performance; several works propose mitigation/estimation methods—
