Blind adaptive MUD with silence listening

This paper presents a blind multi-user detector with an additional adaptive branch which is designed to correct the wrong estimate of the wanted user’s signature caused by a multi-path channel. In order to reach this goal without training sequences, the knowledge of the time periods of silence, i.e. the time periods when the desired user is not transmitting any signal in the channel, is an additional information that is supposed to be available to the receiver.
