Power Amplifier Energy Efficiency Enhancement via Adaptive Polarization-QAM Modulation Scheme in OFDM Systems
In this paper, an adaptive polarization-QAM modulation (APQAM) scheme is proposed to improve the power amplifier (PA) energy efficiency (EE) in orthogonal frequency division multiplexing (OFDM) systems. Since we found that polarization modulation (PM) has better EE performance than QAM in the nonlin...
