Can S-SIX Technology Make Full-Duplex Communication a Reality? (.PDF Download)

CD: Can you tell us about simultaneous self-interference cancellation (S-SIX) technology?

SV: S-SIX is designed to enable wideband (around 1 GHz), low noise figure, tunable self-interference cancellation in both the analog and digital domains. It has traditionally been very difficult to achieve such wide bandwidths, tunability, and low noise figures for analog/RF systems. S-SIX is uniquely capable of achieving this, thus allowing for the design of good interference-cancellation systems.

Interference-cancellation systems that do not possess these characteristics may remove interference, but in doing so, introduce considerable noise. This can drastically impact the link budget, causing the system performance to be poor. Moreover, without wideband tunability, a new component would be required for any changes, giving the system no agility and reconfigurability. S-SIX offers it all in one: a solution that works across bands, with a noise figure that does not impact the link budget while eliminating interference.
