Full-duplex wireless communications using off-the-shelf radios: Feasibility and first results

Melissa Duarte, Ashutosh Sabharwal
2010 2010 Conference Record of the Forty Fourth Asilomar Conference on Signals, Systems and Computers  
We study full-duplex wireless communication systems where same band simultaneous bidirectional communication is achieved via cancellation of the self-interfering signal.  ...  Our experimental results show that while the amount of self-interference increases linearly with the transmitted power, the self-interference can be sufficiently cancelled to make full-duplex wireless  ...  The more separation between interfering antennas the better, but this will have an impact on the size of the wireless nodes.  ...

Elsayed Ahmed, Ahmed M. Eltawil, Ashutosh Sabharwal
2013 2013 Asilomar Conference on Signals, Systems and Computers
