Patent number: 7693179Abstract: A hybrid ARQ retransmission method involves encoding data packets with a forward error correction (FEC) technique prior to transmission. The data packets are re-transmitted based on an automatic repeat request (ARQ) and subsequently soft-combined with previously received erroneous data packets either on a symbol-by-symbol or a bit-by-bit basis. The symbols of the erroneous data packets are modulated by employing a first signal constellation. The symbols of the re-transmitted data packets are modulated by employing at least a second signal constellation. Each symbol bit has a mean bit reliability defined by the individual bit reliabilities over all symbols of the predetermined signal constellation. The first constellation and the at least second signal constellation are selected such that the combined mean bit reliabilities for the respective bits of all transmissions are averaged out.Type: GrantFiled: December 6, 2004Date of Patent: April 6, 2010Assignee: Panasonic CorporationInventors: Alexander Golitschek, Christian Wengerter, Michael Philipp Schmitt, Eiko Seidel

Patent number: 5133508Abstract: An agitator mill has an in each case annular cylindrical exterior grinding chamber and an interior grinding chamber, which are delimitated from each other by a cup-shaped agitator element, the interior grinding chamber and the exterior grinding chamber being connected with each other by bypasses formed in the agitator element for the return of auxiliary grinding bodies. In order to improve the grinding result and to increase the lifetime of the auxiliary grinding bodies or to be able to use even smaller auxiliary grinding bodies without their reaching a separator device arranged ahead of a grinding stock exit, carriers are arranged in the area of the bypasses at the inner casing of the agitator element and extend over a substantial part of the radial width of the interior grinding chamber and into it.Type: GrantFiled: January 30, 1991Date of Patent: July 28, 1992Assignee: Draiswerke GmbHInventors: Norbert Stehr, Philipp Schmitt

Patent number: 5062577Abstract: An agitator mill for the treatment of flowable grinding stock has a grinding receptacle (3) with a mostly closed grinding chamber (9) and a rotatingly drivable agitator element (21) disposed therein. An interior stator (24) is disposed in the agitator element. A grinding stock supply chamber (53) is placed ahead of the grinding chamber. On the same side of the grinding receptacle (3) a separator device (34) is provided through which the grinding stock is discharged again after treatment. In order to prevent to a large extent wear on the separator device (34) and, at the same time, to achieve as even as possible a distribution of the grinding bodies in the grinding chamber (9), the agitator element (21) is designed approximately cup-shaped and disposed between the interior stator (24) and the wall of the grinding receptacle (3) with the formation of an exterior grinding chamber (9') and an interior grinding chamber (9").Type: GrantFiled: November 6, 1989Date of Patent: November 5, 1991Assignee: Draiswerke GmbHInventors: Philipp Schmitt, Norbert Stehr
