Power optimization of wireless systems utilizing space-time block coding and successively refinable source coding

In this paper, power optimization of wireless systems utilizing multiple transmit antennas and successively refinable source coding is considered. We present a solution to a formulation of an optimization problem aimed at minimizing total power consumption of such wireless systems subject to a given level of QoS and an overall available bit rate. Our formulation takes into consideration the power consumption related to source coding, channel coding, and layered transmission of multiple transmit antennas. In our study, we consider a Gauss-Markov source model, a Rayleigh fading channel along with the Gilbert-Elliott loss model, and a space-time transmission block code.
