In this paper, the authors consider a wireless multimedia system by mapping Scalable Video Coded (SVC) bit-stream upon Super-Position 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. Their 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.
