Error performance of CE-OFDM based AF systems with relay selection by Tao JIANG, Guangqiu LI, Jianhui CAI

“…Constant envelope (CE) orthogonal frequency division multiplexing (OFDM) can develop the advantages of OFDM,and eliminate the shortcomings of high peak-to-average power ratio (PAPR) and sensitivity to non-linear distortion of power amplifiers.The error performance of OFDM based amplify-and-forward (AF) cooperative system with relay selection will be deteriorated due to feedback delay and other factors.Minimum mean square error (MMSE) Wiener channel predictor can alleviate the deterioration of error performance of wireless systems caused by feedback delay.For this reason,the CE-OFDM based AF cooperative system with relay selection and MMSE channel prediction which can overcome the shortcomings of OFDM and the influence of feedback delay was proposed,and its lower bound expressions for the average bit error rate (ABER) of rectangular quadrature amplitude modulation over Rayleigh block fading channels were derived.The numerical calculation and simulation results show that the lower bound expressions for the ABER of the above system has high accuracy when the modulation coefficients are small and can be used to design the AF cooperative system with CE-OFDM,channel prediction,and relay selection.…”

Omni directional video coding rate distortion optimization method based on weighted-to-spherically-uniform structural similarity by Yufeng ZHOU, Mei YU, Baozhen DU, Yang SONG, Gangyi JIANG

“…Aiming at the shortcomings of the coding rate distortion model in traditional video coding,considering the characteristics of equal rectangular omnidirectional video,a method of omnidirectional video coding rate distortion optimization based on spherical weighted structural similarity (WS-SSIM) was proposed.By considering the distortion of the internal structural similarity of the projection plane and the relationship between the spherical distortion and the projection plane distortion,the “spherical weighted structural similarity” was proposed to describe the degree of distortion of the planar omnidirectional image local block relative to the viewing sphere,which was applied to the rate-distortion optimization process of omnidirectional video coding and adaptive selection of quantization parameters to improve vision-based coding efficiency.The experimental results show that compared with the HEVC video coding standard HM16.9 test platform,the proposed method can save an average of 24.48% code rate under the same visual quality,which indicates that the method has significant performance for improving the omnidirectional video coding rate distortion performance.…”
