Lagrange multiplier selection based on SATD for H.265/HEVC

open access: yesTongxin xuebao, 2017
In order to improve the coding performance of intra rough mode decision,a SATD-based Lagrange multiplier selection algorithm was proposed for H.265/HEVC.The characteristic of Hadamard transform was first analyzed,and following the new Lagrange multiplier

PAPR reduction of optical OFDM signals in visible light communications

open access: yesICT Express, 2019
Orthogonal frequency division multiplexing (OFDM) is extensively used in optical communications to achieve high rate transmission. In this paper, Vandermonde like matrix (VLM) pre-coding approach is offered to reduce the high peak-to-average power ratio (
