A Cross-Layer Architecture for Motion-Adaptive Video Transmission Over MIMO Channels
In this paper, the authors study the impact of spatio-temporal variations of a video sequence on wireless MIMO video transmission. In the light of their findings, they propose a cross-layer MIMO video communication architecture for efficient multimedia communication. Existing methods complement Spatial Multiplexing (SM) and Space Time Block Coding (STBC) with enhanced source and channel coding strategies to improve video PSNR at a MIMO receiver. However, these methods ignore the adverse impacts of spatio-temporal content variations on video quality and decoding complexity.
