Popis: Due to high data rates and limited bandwidth as well as limited battery power, wireless multimedia communications systems must be optimized in every possible way. We develop a generic matching scheme for wireless image and video communication in which the three most significant components: the source coder, the channel coder, and hardware power consumption, are jointly optimized. That is, we maximize the end-to-end image quality subject to a total power constraint on both the RF transmission power and the power consumption of the digital implementation of the channel coder, which represents a major portion of the total hardware power in short-range applications.
