Statistical Characterization of Power Amplifier Nonlinearity at 60 GHz: MIMO Beam-forming Analysis

This paper presents an analytical framework to model and characterize the power amplifier nonlinearity at 60 GHz. Using extension of Bussgang theorem, we propose a closed form expression for the variance of power amplifier nonlinearity noise as a function of the power amplifier output backoff. The variance is subsequently used to estimate the capacity of MIMO beam-forming subject to the power amplifier nonlinearity at the transmitter.
