This portfolio from Prof. Sachin Katti's lab at Stanford comprises five inventions that collectively enable full-duplex wireless communication, allowing radios to transmit and receive simultaneously on the same frequency.
The technologies address the core challenge of self-interference cancellation through adaptive tuning, programmable filtering for fragmented spectrum, and advanced multi-tap cancellation techniques. The portfolio culminates in prototype-validated single-antenna (SISO) and 3x3 MIMO full-duplex radios achieving near-theoretical doubling of throughput using standard WiFi PHY.
Applications span enterprise WiFi, cellular networks, LTE base stations, and point-to-point links.
