High sidelobes of orthogonal frequency-division multiplexing (OFDM) signals must be resolved for future wireless communications. In this study, we propose and analyze an efficient orthogonally linear precoding to suppress the sidelobes in OFDM systems. The proposed scheme uses a decomposed precoder on the real domain for a successive N-continuous technique. Comprehensive theoretical analyses justi...
