Simultaneous Transmission and Reception (STAR) on Shared 77-81 GHz Bands
Deploying analog RF circulators and digital finite-impulse-response (FIR) cancellation filters to eliminate >110 dB of self-interference when transmitting and listening simultaneously.
Multi-Stage Hybrid Cancellation Topologies
Analog cancellation taps cancel 70 dB of power at the antenna feed, allowing digital baseband estimators to scrub the remaining 40 dB with zero receiver saturation.
- Enables simultaneous gigabit V2X transmission and millimetric radar sensing.
- Over 110 dB total self-interference suppression across 4 GHz bandwidth.
- Reclaims 50% of otherwise fragmented automotive radio spectrum.
- Compliant with ITU-R and ETSI automotive radar regulatory mandates.
