H.264 rate-distortion model based joint source channel coding scheme over wireless channels
Published 2008-01-01“…A new rate-distortion model of H.264 encoder was firstly set up according to the rate distortion(R-D) charac-teristics of H.264.Then,the end-to-end video transmission distortion was analyzed and based on the R-D model of the H.264 encoder and the error combat characteristics of the Turbo code,an adaptive joint source channel coding(JSCC) over wireless channel was proposed,which could optimize the rate allocation of the available network bandwidth be-tween source coding and channel coding adaptively according to the actual condition of current wireless channel,so as to improve the robustness of the video transmission.The experiment results indicate that,compared with fix choice of channel coding rate,the proposed JSCC scheme is can greatly improve the transmission robustness and achieve better reconstructed video quality at the receiver.…”

Analysis of operational channel selection of dynamic spectrum sharing wireless communication system based on RF front-end
Published 2011-01-01“…Because of the existence of primary user signals and the inevitable nonlinearity of some RF devices,the inter-ference signals such as three-order intermodulation signal would be produced in the front-end of RF receiver.To reduce the impact of interference signals,the interference which was caused by primary user signals to dynamic spectrum shar-ing wireless communication system was analyzed on the front-end of RF receiver side.Then,the restriction on opera-tional channel selection of dynamic spectrum sharing wireless communication system was derived.By following the re-striction,the negative effects caused by interference signals could be reduced and the quality of communication in dy-namic spectrum sharing system was guaranteed.Finally,availability of the restriction on operational channel selection is verified experimentally in UHF dynamic spectrum sharing wireless communication system.…”
