Abstract

The self-interference (SI) channel in full duplex transceivers is investigated. The SI channel is measured using ultra wide-band antennas. Narrow-band measurement technique is used for the channel measurements so that spatial resolution of 4.3 cm is achieved. Measurements are done in a variety of locations including an anechoic chamber with different antenna orientation. Antennas are mounted on an old laptop frame. Coherence bandwidth of the SI channel is found to be varying between 1 MHz and 4 MHz, effectively making it a frequency selective channel. It is also observed that a major amount of power is transferred because of direct coupling between the antennas via the frame on which antennas are mounted.
