Modeling and Compensation of Non-Linear Effects in Highly Integrated MIMO Transmit Arrays

This talk presents a computationally efficient multi-physical modeling framework suitable for integrated-circuit transmitters, enabling joint analysis of power-amplifier behavior, antenna interactions, and communication/sensing signals within a unified environment. Combined with circuit-aware digital signal processing for impairment identification and compensation, the approach is demonstrated through simulations and measurements from various transmitter prototypes, illustrating how system-level insight can drive improved PA efficiency and linearity in future wireless systems.
