Abstract
This paper proposes a cooperative multiple-input multiple-output (MIMO) architecture to transmit the video reliably. By exploring the configurable resources of the scalable video and the coded MIMO system, we further propose a novel joint source-channel coding (JSCC) framework with optimal tradeoff among diversity, multiplexing and coding gains. In this framework, the concatenated low-density parity-check codes (LDPC) and diversity-embedded space-time block codes (DE-STBC) provide double unequal error protection for the video layers, and the STBCs switching enables the adaptability to the varying channel. Experiments demonstrate the superiority of cooperative architecture and the effectiveness of our JSCC algorithm.
