N2 - In-band full-duplex (IBFD) transmission has the potential to nearly double the throughput by improving the spectral efficiency. To achieve this, the self-interference (SI) at the receiver due to one's own transmission must be suppressed, such that it does not obscure the desired signal. Compact on-frequency repeaters are suitable candidates for initial implementation of IBFD. However, the design, evaluation, and optimization of such systems require realistic SI channel models. In this contribution, we characterize measured multiple-input multiple-output (MIMO) SI channels as a 2-D site-specific geometry-based stochastic channel model. The model includes smooth walls causing specular reflections, diffuse scatterers along the smooth walls, and mobile scatterers modeling pedestrians and vehicles.
