    Piecewise-linear companding transform for peak-to-average power ratio reduction of OFDM signals by YANG Pin-lu, HU Ai-qun

    Published 2011-01-01
    “…In order to reduce the peak-to-average power ratio(PAPR) of orthogonal frequency division multiplexing(OFDM) signals,a piecewise-linear companding transform was proposed.Small amplitudes were multiplied by a scale factor,while large ones were not only multiplied by a scale factor but also added by a shift.The resulting companding transform was piecewise-linear and continuous.It can provide significant PAPR reduction performance with low compu-tational complexity,and has low influence on system performances through piecewise transform.It is shown by theoreti-cal analysis and simulation that,a good trade-off between PAPR reduction and bit-error-rate performances can be achieved by carefully choosing the two scales and the shift.Furthermore,compared with existing linear and nonlinear companding transforms,a better power spectral density performance can be achieved.…”

    A new method to predict average flow velocity and conveyance capacity of meandering streams by Cristopher Alexander Gamboa-Monge, Ana Maria Ferreira-da-Silva, Laura Segura-Serrano, Isabel Guzmán-Arias

    Published 2020-07-01
    “…In addition, it is determined that the most influential components for the resistance factor in meandering conditions depend on the relation between channel-averaged flow depth (hav) and the average grain size of the bed material (D50), the deflection angle of a meandering flow at the crossover Oi (θ0), and also the relation between flow width (B) and the channel-averaged flow depth (hav); these relations are used to develop a mathematical expression capable to predict the resistance to flow due to the meandering of the stream. …”
