Cross-layer optimization for 3-D video transmission over cooperative relay systems

作者：

Highlights：

• A novel optimization algorithm using Lagrange multiplier is proposed to solve the optimum problem.

• We investigate the impacts of relay selection on the video system performance.

• Estimation procedures of the total SNR are proposed to control the source and destination nodes.

• We investigate the impacts of total instantaneous SNR estimation on the video system performance.

• The performance of video system is very sensitive to the accuracy of the total SNR estimation.
