Abstract

Abstract: The nonlinear characteristics of power amplifiers are always ignored in the research of wireless sensor network system in which the single carrier quadrature amplitude modulation is adopted. In fact, the effect of the nonlinear characteristics of power amplifiers on the system is also very important. In this paper, we assume the characteristics of the power amplifier, which is processed with nonlinear distortion compensation, as the approximate ideal class A of power amplifier. The different effects of the power amplifier are analyzed from the roll-off coefficient of the filter and the power regression of the power amplifier aspects on the three parameters of constellation, power spectral density, and symbol error rate. The simulation results verify our theoretical analysis.

Key words: QAM, ideal power amplifier, power back-off, WSN
