An efficient nonlinear companding transform (NCT) scheme is proposed for reducing the peak-to-average power ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) signals. The proposed new scheme transforms the Gaussian-distributed signals into the specified statistics form based on a piecewise function. By choosing the companding coefficients,(More)
A GRA-BKP (Grey Relational Analysis-Bounded Knapsack Problem) scheme was proposed for the radio resource management of the 5G networks. It consists of two steps, access selection and admission control. The former step was executed via GRA, whereas the latter problem was formulated as a bounded knapsack problem. Accordingly, an optimal solution of the BKP(More)
