If SNR cur =SNR pre +d 1 |
then J cur=J pre−d 2, |
where SNR cur and SNR pre represent the input SNR after and before |
increasing its value, |
J cur and J pre denote the corresponding buffer size before and after |
decreasing its value, |
d 1 and d 2 are the step sizes for the SNR and the buffer size, respectively. |
