Optimal Link Adaptation in Wideband CDMA Systems

Overview In this paper a general framework is developed for optimizing link adaptation for multiuser CDMA systems in the wideband limit. The framework is then used to solve for the optimal power control policy that minimizes average transmit power while satisfying a constraint on the per-user probability of packet loss due to deadline expiration. The optimal link adaptation is found through an infinite horizon dynamic program. Typical dynamic programming formulations do not perform well for CDMA systems since the size of the problem grows exponentionally with the number of users.

Gmail cookie flaw 'puts email at risk'

But that scenario is certainly less than optimal. According to Gatford, attackers could compromise a Gmail account - using a cross-site scripting [XSS] vulnerability - if the victim is logged in and clicks on a malicious link.
