Waveforms for the Massive MIMO Downlink: Amplifier Efficiency, Distortion and Performance
, 2015 In massive MIMO, most precoders result in downlink signals that suffer from high PAR, independently of modulation order and whether single-carrier or OFDM transmission is used. The high PAR lowers the power efficiency of the base station amplifiers.
