AbstractThis paper presents experimental characterization of the self-interference (SI) channel for In-Band Full-Duplex (IBFD) communication systems that employ beam steering, Multi reconfigurable antennas (MRA), for passive SI suppression. First, we describe a system model of a full-duplex base station while highlighting channel impairments associated with each signal component. We present the SI channel power delay profiles measured by IBFD system operating on 5MHz, 10MHz and 20MHz bandwidths. We compare the measurements for beam patterns that result in line of sight suppression (and non-suppression) in both static and dynamic environments. We then statistically model the SI channel by performing probability distribution fitting to SI channel data, which is collected in dynamic environment, under high and low SI suppression conditions provided by MRA. Finally, candidate probability distribution models are compared using goodness of fit test.
