Abstract

Early detection of the entrance of a new user into a multiuser communication channel is considered. The matrix CUSUM (cumulative-sum) test, a multialternative quickest change detection method, is introduced and then applied to this problem. The general behavior of this algorithm is described in analytical results and simulations.
