Joint Maximum Likelihood Sequence Estimation algorithm for decollision of AIS signals in maritime surveillance context

This paper addresses the Joint Maximum-Likelihood Sequence Estimation (JMLSE) algorithm of AIS (Automatic Identification System) signals decollision in maritime surveillance context. The AIS is a Self-Organized Time Division Multiple Access (SO-TDMA) system, in which vessels periodically transmit information. The main idea of this paper is the decollision of signals received by a Low Earth Orbit (LEO) satellite lead to a global surveillance of maritime traffic using JMLSE algorithm. Simulations are provided in order to evaluate the behavior of the JMLSE algorithm for separation and estimation of sources
