Abstract
This paper proposes a novel solution to cross-layer optimization for streaming of image/video over adaptive MIMO-OFDM wireless networks. Joint source-channel coding (JSCC) that includes progressive coding and adaptive modulation/code set (MCS) is applied to a singular value decomposition (SVD)-based MIMO-OFDM transmission system. Armed with a packet error rate (PER) model that considers modulation, code rate and SNR, we present a novel resource allocation algorithm that determines the optimal set of parameters. Wireless transmission simulation indicates that the proposed design can deliver images at same level of PSNR with 3–5dB smaller required channel SNR than the conventional approach.
