Communication systems face challenges from high-power adjacent
channel signals, or blockers, inducing nonlinear behavior in RF front
ends. Ensuring robust performance in the presence of blockers is
crucial for IoT and other spectrum-consuming devices coexisting with
advanced transceivers. This paper proposes a flexible, data-driven
solution using a Deep Belief Network (DBN) to mitigate third-order
intermodulation distortion (IMD) during demodulation. Numerical
evaluations of AI-enhanced receivers employing DBN as an IMD
canceler and demodulator show significant improvements in bit error
rate (BER) performance. The effectiveness of DBN varies with RF
front end characteristics, notably the third-order intercept point (IP3).
