Abstract
A power-allocation method for scalable video transmission over MIMO system includes: encoding a video sequence into L layers; performing MCSs to the layers and estimating bit error rate or symbol error rate respectively for each of the layers after MCSs procedure based on channel quality feedbacks from the receiver side; performing power allocations of L sub-problems and obtaining candidate power allocation solution of each of the sub-problems respectively based on bit error rate or symbol error rate of each of the layers and derivative of bit error rate or symbol error rate of each of the layers; and choosing one of the candidate power allocation solution with the largest quality of experiences as the power allocation of the scalable video transmission over MIMO system. This invention considers transmission-error-rate of PHY layer and video coding structure of APP layer and optimizes quality of experiences at user end with cross-layer design.
