—A non-parametric technique to model the behavior of power amplifiers is presented. The proposed technique relies on the principles of density estimation using the kernel method and it is suited for the application of power amplifier modeling. The proposed methodology transforms the input domain to an orthogonal memory domain. In such a domain,(More)
This paper analyzes the joint effects of in-phase and quadrature (I/Q) imbalance and power amplifier (PA) distortion for RF multiple input multiple output (MIMO) transmitters in the presence of crosstalk. This paper proposes candidate models for the digital predistortion of static I/Q imbalanced sources exciting a dynamic MIMO Volterra system. The proposed(More)
