The combination of massive multiple-input multiple-output (MIMO) with beamforming (BF) and orthogonal frequency division multiplexing (OFDM) signaling can achieve high-rate data transmission with wide coverage area thanks to the high BF gain. The drawback to this transmission scheme is its high peak-to-average power ratio (PAPR). High PAPR is due to the transmission power variation among transmission antennas due to BF in addition to the multicarrier-based OFDM signaling. This paper investigates the performance of our previously reported adaptive PAPR reduction method using null space of MIMO channel in the eigenmode massive MIMO-OFDM signals. The adaptive PAPR reduction method using null space of MIMO channel can mitigate the data throughput degradation due to the interference from the PAPR reduction signal generated by the clipping and filtering (CF) algorithm, by restricting the transmission of PAPR reduction signal only to the null space of MIMO channel. In the massive MIMO scenario, since the number of spatial streams is in general much less than that of the transmitter antennas, the effect of the adaptive PAPR reduction method is expected to be enhanced due to the increase in dimension of the null space of MIMO channel. Computer simulation results show that the adaptive PAPR reduction method is effective especially when (i) the number of the transmitter antennas is large, (ii) the required PAPR is low, and (iii) the signal-to-noise ratio (SNR) is high. |
