Abstract :
This paper proposes a simplified algorithm for linearizing MIMO nonlinear systems. The linearization technique is designed for MIMO systems with nonlinear cross-talk. The new algorithm relies on estimating the coupling factor and building the 2×2 DPD based on two 1×1 DPDs. The algorithm is around two times faster than the conventional method whilst the performance is reasonably close to the conventional technique.
