Cognitive radio assisted quality compensation for scalable video multicast in cellular networks

作者：

Highlights：

• A novel cognitive radio assisted video quality compensation scheme is proposed.

• An easily-implemented spectrum access scheme is presented.

• An adaptive relay rates scheduling scheme is proposed.

• The performance of the proposed scheme attributed to several important factors is systematically evaluated.
