Power Optimization of Wireless Media Systems With Space-Time Block Codes
We present analytical and numerical solutions to the problem of power control in wireless media systems with multiple antennas. We formulate a set of optimization problems aimed at minimizing total power consumption of wireless media systems subject to a given level of QoS and an available bit rate. Our formulation takes into consideration the power consumption related to source coding, channel coding, and transmission of multiple-transmit antennas. In our study, we consider Gauss–Markov and video source models, Rayleigh fading channels along with the Bernoulli/Gilbert–Elliott loss models, and space–time block codes.
