Cross-layer optimization for wireless streaming via adaptive MIMO OFDM

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...

Description
Summary: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.
