Full-duplex testbed with a base station, transmit and receive antennas, and power amplifiers — Fig. 8(a). Flexible-duplex proof-of-concept testbed; cropped from the original figure.

Nonlinear self-interference (SI) cancellation is essential for mitigating the impact of transmitter-side nonlinearity on overall SI cancellation performance in flexible duplex systems, including in-band full-duplex (IBFD) and sub-band full-duplex (SBFD).
