Presented in this study is a novel precoding scheme for orthogonal frequency division multiplexing systems to suppress the out‐of‐band emission (OOBE). The scheme suppresses the OOBE by making the transmitted signal satisfy the continuous derivative property and the notched frequency (NF) property, which have been proposed separately in some existing schemes. Unlike most of the continuous derivative related schemes that require iterative decoders, authors’ scheme employs a non‐iterative decoder. Numerical results show that their proposed scheme achieves superior OOBE suppression than the other non‐iterative continuous derivative precoding schemes and NF schemes. Computational complexity, peak‐to‐average power ratio, and bit error rate are also analysed.
