This paper proposes a peak-to-average power ratio (PAPR) reduction method that utilizes the null space in a multiple-input multiple-output (MIMO) channel for downlink MIMO-orthogonal frequency division multiplexing (OFDM) signals with multiple-antenna amplify-and-forward (AF)-type relaying. In order to achieve sufficient coverage enhancement using beamforming with multiple antennas an... https://foldlyers.shop/product-category/front-loader/
