Abstract

Adaptive modulation is an effective scheme to observably improve the performance of interactive video data transmission over mobile wireless channels. The effectiveness of adaptive modulation is affected by the accuracy of channel quality estimation. We analyzed in this paper the effect of channel quality estimation error on the performance of the adaptive modulation scheme with four parameters we proposed: Extra BER Cost (EBC), Potential Theoretical Channel Capacity Loss (PTCCL), average system EBC (EBCs) and average system PTCCL (PTCCLs). Without considering the details of specific multimedia information to be transmitted, our measurements are simple and direct.
