Achieving single channel, full duplex wireless communication
This paper discusses the design of a single channel fullduplex wireless transceiver. The design uses a combination of RF and baseband techniques to achieve full-duplexing with minimal effect on link reliability. Experiments on real nodes show the full-duplex scheme achieves a median gain of 84% in aggregate throughput as compared to traditional half-duplexing wireless for a single hop network. This paper presents using Antenna Cancellation, a novel technique for self-interference cancellation. In conjunction with existing RF interference cancellation and digital baseband intereference cancellation, antenna cancellation achieves the amount of self-interference cancellation required for fullduplex operation. The paper also discusses potential MAC and network gains with full-duplexing. It suggests ways in which a full-duplex system can solve some important problems with existing wireless systems including hidden terminals, loss of throughput due to congestion, and large end-to-end delays...
