Abstract

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.

摘要

我们给出了具有多天线的无线媒体系统中功率控制问题的解析解和数值解。我们制定了一组优化问题，旨在在给定的服务质量（QoS）水平和可用比特率的条件下，使无线媒体系统的总功耗最小化。我们的公式考虑了与源编码、信道编码以及多发射天线传输相关的功耗。在我们的研究中，我们考虑了高斯 - 马尔可夫和视频源模型、瑞利衰落信道以及伯努利/吉尔伯特 - 埃利奥特损耗模型，还有空时分组码。
