Perturbation-Assisted PAPR Reduction for Large-Scale MIMO-OFDM Systems via ADMM

10 Jul 2016 Bao Hengyao Fang Jun Chen Zhi Jiang Tao

We consider the problem of peak-to-average power ratio (PAPR) reduction for orthogonal frequency-division multiplexing (OFDM) based large-scale multiple-input multipleoutput (MIMO) systems. A novel perturbation-assisted scheme is developed to reduce the PAPRs of the transmitted signals by exploiting the redundant degrees-of-freedom (DoFs) inherent in the large-scale antenna array...
