Gen-2 Open-Access Wideband Full-Duplex Radios
The PCB design of the Frequency Domain Equalization- (FDE)-based RFIC canceller that was presented in  is available below. A preliminary version of the system with this PCB canceller was presented in . A detailed discussion and system- and network-level evaluation of the canceller are available in .
Gen-2 FDE-based RF canceller
Please email Tingjun Chen (tingjun [at] ee.columbia.edu) if you use (or plan to use) the design of the FDE-based PCB canceller, or if you have any questions. We are currently working on an improved version of the PCB canceller and the design will be made available soon.
- PCB design (v1) (DesignSpark v8.1, for the PCB design and schematics)
- PCB design Gerber files (v1) (for PCB fabrication)
