Patent number: 7725798Abstract: A method and system for recovering useful information, in particular useful information transmitted in digital form on terrestrial or satellite-based information paths, for example as voice, image or data signal, from channel-coded data streams encoded with turbo codes with a predefined code rate is disclosed. The data streams are received by a turbo decoder with a presettable number of decoder components and subsequently decoded in an iterative process according to the MAP and/or Max-Log-MAP standard. The iterative process is controlled by a stop criterion, wherein after termination of the iterative process in the turbo decoder at least one of the decoder components, in particular the associated lattice diagram, is used for an additional decoding process that is different from the MAP and/or Max-Log-MAP standard. This approach lowers the error floor of the turbo code.Type: GrantFiled: February 24, 2005Date of Patent: May 25, 2010Assignees: Joanneum Research Forschungsgesellschaft mbH, Technische Universität Graz Institut für Kommunikationsnetze und SatellitenkommunikationInventors: Johannes Ebert, Wilfried Gappmair
