In this paper, we devise a new convex optimization strategy to both reduce the peak-to-average power ratio (PAPR) and the PAPR variance of orthogonal frequency-division multiplexing (OFDM) symbols. There are three distinctions of our proposed method as compared to existing methods: 1) PAPR, error vector magnitude (EVM), and free subcarrier power overhead(More)
In many wireless communications/radar applications, constant modulus sequences with low correlation sidelobes levels are desired. In this letter, we present an efficient optimization method to design them. Firstly, we formulate a fourthorder polynomial, but unconstrained, minimization problem. And then, a customized LBFGS (Limited-Memory Broyden Fletcher(More)
