A rate-distortion optimized method for ARQ bit allocation
Gao Xiu-feng · 2006
An optimal rate-distortion model was proposed to improve picture quality according to error-prone wireless channel status for an ARQ system.This model combined intra refresh error resilience method with bit allocation for channel coding and source coding.Experiment shows that the optimal scheme can achieve higher quality than general ARQ system at the same environment (channel capacity and packet loss rate),especially in low bit rate channel.
