Abstract :
A Cartesian Feedback-Feedforward Transmitter for improving the linearity of the transmit path for high-data rate communications is described. A Volterra Series representation is used to analyze the linearity of the architecture. System simulations are used to demonstrate linearity enhancements achieved through a combination of feedback and feedforward.
