A link adaptation strategy for wireless multimedia transmission

In the context of multimedia wireless transmission, a link adaptation strategy is proposed, assuming that the source decoder may accept some remaining errors at the output of the channel decoder. Based on a mean bit error rate for erroneous frames criterion, a target bit energy-to-equivalent noise ratio is chosen. Under this constraint, a maximization of the minimum user information rate is applied through dynamic spreading gain and power control, allowing to guarantee a transmission for each and every user.
