In-band Full-duplex Waveform Coexistence for Joint Communication and Sensing

Advantages

  • Simultaneous communication and sensing maximize how efficiently spectrum resources are used
  • System capacity grows by removing the need for separate dedicated frequency bands
  • Advanced interference cancellation significantly improves signal clarity and overall reception quality
  • Flexible deployment supports cellular networks, vehicle communications, monitoring, and interference detection

Summary

Wireless networks are buckling under the weight of spectral congestion. As connected devices multiply, the demand to unify data communication and environmental radar sensing into a single platform has never been greater. Relying on isolated systems for data transfer and spatial awareness is simply unsustainable, and the pressure to execute simultaneous communication and sensing within the same time and frequency resources is now critical.

This technology enables a transceiver to simultaneously transmit and receive signals across the same time and frequency resources by generating a superimposed signal that combines distinct communication and radar sensing waveforms. Unlike conventional approaches that compromise a single waveform for dual purposes, it uses dedicated, separable waveforms for each function. Advanced self-interference cancellation eliminates both direct path leakage and multipath reflections, enabling true full-duplex operation with no performance degradation across applications from cellular networks to vehicle-to-vehicle communications.
