SNDR Analysis for Transceiver Nonlinearities in AWGN Channels

Nonlinear effects can significantly degrade the performance of communication systems. We propose a signal-to-noise-and-distortion ratio (SNDR) analysis framework for the general case when nonlinearities exist at both the transmitter and the receiver. In some cases, the nonlinearities can be modeled by polynomials, and closed-form expressions for the SNDR are possible. We provide examples to illustrate the usefulness of the analysis and the insight that closed-form SNDR analysis provides.
