在本文中，我们考虑了一个无线多媒体系统的映射可伸缩视频编码（SVC）的比特流叠加编码（SPC）信号，简称（SVC-SPC）结构。使用软件定义无线电（SDR）仿真器进行实证实验，以更好地了解其效率，具体来说，由于不同的功率分配比的接收信号的影响。我们的实验结果表明，为了保持高的视频质量，分配给基本层的功率应该比分配给增强层的功率高大约四倍。
In this paper we consider a wireless multimedia system by mapping scalable video coded (SVC) bit stream upon superposition coded (SPC) signals, referred to as (SVC-SPC) architecture. Empirical experiments using a software-defined radio(SDR) emulator are conducted to gain a better understanding of its efficiency, specifically, the impact of the received signal due to different power allocation ratios. Our experimental results show that to maintain high video quality, the power allocated to the base layer should be approximately four times higher than the power allocated to the enhancement layer.
