Abstract
Conventional two-way wireless communication nodes require separate channels to receive or transmit. The two channels are usually multiplexed in time and/or frequency. A system which can support both links (transmit and receive) at the same time is referenced as a as a full duplex system. Systems and methods are described to create the two links simultaneously, overlapping in frequency and in time domains, while avoiding the hardware complexity and/or lack of flexibility inherent to conventional systems, by reducing the amount of self interference between transmitter and receiver sections. The self interference may be reduced by using at least one of antenna design techniques comprising antenna selection and signal processing techniques to maximize the signal-to-interference plus noise ratio.
