Patent number: 7830952Abstract: The computational complexity required for interference suppression in the reception of wireless communications from multiple users is reduced by sharing information among the users. In some situations, information indicative of a statistical characteristic of the interference is shared among the users. Delays used to produce the interference statistic information are determined based on rake finger delays employed by the users. In some situations, a parameter estimate that is used to calculate combining weights for the users is shared among the users.Type: GrantFiled: February 13, 2006Date of Patent: November 9, 2010Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Hakan Bengt Eriksson, Carmela Cozzo, Ali S.

Publication number: 20050036881Abstract: A device for continuous and individual feeding of sheets from a stack to a depositon site comprises gripping members (15) for grasping and hoding the sheets, and a movement device for displacing the gripping members (15) between the stack and the deposition site. The movement device displays two arms (12, 13), which are provided with the gripping members (15). The arms (12, 13) are pivotal about a vertical pivot axis (14) and are movable therealong in the verical direction to positions (33) for both depositing and picking a sheet. Further, the one arm (12, 13) may be pivoted past the other (12, 13). A feeder station for feeding in accordance with the foregoing includes at least one sheet stack, a deposition site and a feeder device. The stack and the deposition site are disposed on a common arc of a circle, and the feeder device has a pivotal arm (12, 13) which is provided with gripping members (15).Type: ApplicationFiled: June 14, 2002Publication date: February 17, 2005Inventors: Bengt Eriksson, Brodde Bengtsson

Patent number: 6101224Abstract: An apparatus and method generate a linearly modulated signal in a polar modulation system. A signal for transmission is separated into a phase component and an amplitude component, and a carrier signal is modulated with the phase component in a phase modulator, creating a phase distortion. A compensator compensates for the phase distortion created by the phase modulator by modifying the amplitude component. The phase modulated carrier signal is amplitude modulated by the compensated amplitude component to produce a linearly modulated signal.Type: GrantFiled: October 7, 1998Date of Patent: August 8, 2000Assignee: Telefonaktiebolaget LM EricssonInventors: Bengt Lindoff, H.ang.kan Bengt Eriksson

Patent number: 5986512Abstract: A .SIGMA..DELTA. modulator-controlled, phase-locked-loop circuit, and an associated method, generates a frequency-regulated signal which does not exhibit undesired tones. Dithering signals are generated and are provided to a .SIGMA..DELTA. modulator. The .SIGMA..DELTA. modulator forms a division-factor control signal used to control the division factor of a frequency divider forming a portion of the PLL circuit. The dithering signals applied to the .SIGMA..DELTA. modulator reduce the likelihood that the .SIGMA..DELTA. modulator shall enter a limit cycle and generate repetitive output signals.Type: GrantFiled: December 12, 1997Date of Patent: November 16, 1999Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventor: H.ang.kan Bengt Eriksson

Patent number: 5013183Abstract: The invention relates to an apparatus for drawing off ground air under the foundation slab of a house. A tube is placed in an excavation made some meters away from the house. The bottom end part of the tube is downwardly open and is provided with a plurality of rows of holes through which a blower, arranged inside the pipe, draws air from the ground. The ground air which is withdrawn departs via an evacuation duct opening out above the ground surface. A lid is arranged airtight at the upper end of the tube. The evacuation duct connects up with the tube in an area above the blower.Type: GrantFiled: September 29, 1989Date of Patent: May 7, 1991Inventors: Bengt Eriksson, Bertil Clavensjo
