In massive multi-input multi-output (mMIMO) orthogonal frequency division multiplexing (OFDM) systems, reduction of high peak-to-average power ratio (PAPR) is a challenging problem. Although deliberate amplitude peak limiting is a promising PAPR reduction approach, it causes un-desired nonlinear in-band distortion and out-of-band radiation. Thus, the joint use of a peak limiter and band-limitation filter such as clipping-and-filtering (CF) is required. The objective of this paper is to evaluate the effect of CF based PAPR reduction for mMIMO-OFDM systems, where a band-limitation filter is designed to limit out-of-band radiation due to clipping while mitigating peak amplitude regrowth due to filtering. We discuss the effect of utilizing extra degrees of freedom for compensating in-band distortion due to CF in mMIMO systems. Simulation results verified the effectiveness of the above approach in terms of instantaneous peak power, adjacent channel leakage power ratio (ACLR) and signal-to-distortion power ratio (SDR) in mMIMO-OFDM downlink.
