In LEGO-Fi, we propose a key concept called cross-demapping, which leverages the mapping between the distinguishable patterns of ZigBee/Bluetooth symbols to decode ZigBee/Bluetooth signals. We take ZigBee-to-WiFi CTC as an example, highlights of our design mainly include: (1) the light-weight downsampling technique to bridge the bandwidth gap between ZigBee and WiFi, (2) exploiting the periodicity of ZigBee preambles to detect ZigBee packet at WiFi, (3) the symbol synchronization scheme built on top of the SFD structure, and (4) the matching filter based cross-demapping scheme.
