Novel Baseband Equivalent Models of Quadrature Modulated All-Digital Transmitters
Omer Tanovic, Rui Ma, Koon Hoo Teo
In this paper an exact baseband equivalent model of a quadrature modulated all-digital transmitter is derived. No restrictions on the number of levels of a digital switched-mode po…

Baseband Equivalent Models and Digital Predistortion for Mitigating Dynamic Continuous-Time Perturbations in Phase-Amplitude Modulation-Demodulation Schemes (Expanded version)
Omer Tanovic, Alexandre Megretski, Yan Li +2
We consider baseband equivalent representation of transmission circuits, in the form of a nonlinear dynamical system in discrete time (DT) defined by a series interconn…

Discrete-Time Models Resulting From Dynamic Continuous-Time Perturbations In Phase-Amplitude Modulation-Demodulation Schemes
Omer Tanovic, Alexandre Megretski, Yan Li +2
We consider discrete-time (DT) systems S in which a DT input is first tranformed to a continuous-time (CT) format by phase-amplitude modulation, then modified by a non-linear CT dy…
