With the proliferation of smart wireless devices in our homes, the cross-technology interference increasingly becomes an important issue. This paper presents a novel smart relay system, called SpaceHub, which leverages an multi-antenna relay node to mitigate cross-technology interference for all communicating devices which may only have single antenna. In SpaceHub, the relay node overhears wireless communications in the air, separates the collided signals, and forwards the separated (cleaned) signals to their intended receivers without a prior knowledge of the wireless signal structures. The core component of SpaceHub is a blind signal separator that constructs spatial filters using the angle-of-arrival information of collided signals. We have implemented SpaceHub on a software radio platform and our evaluation shows SpaceHub signal separator can suppress the interference up to 23dB, and is robust against the power or relative locations of interfering signals. |
