Patent number: 7340498Abstract: Apparatus and method for determining a fixed point in a mobile communication system are disclosed. An initial fixed point is set through simulation and a saturation for an output of a target device is compared with a reference saturation. Then, the position of the initial fixed point is adaptively changed according to the change in the output range of the target device. Therefore, when a floating point is converted into a fixed point, the performance of the system can be improved while the complexity of the hardware can be reduced.Type: GrantFiled: May 28, 2003Date of Patent: March 4, 2008Assignee: LG Electronics Inc.Inventors: Tan Joong Park, Sung Lark Kwon, Hee Gul Park

Patent number: 7058361Abstract: A method and apparatus for performing channel compensating in a mobile communication terminal calculates a channel prediction value by varying an energy cumulative interval based on channel variation occurring in a radio channel. In accordance with one illustrative embodiment, the energy cumulative interval is varied from a minimum 2T to a maximum 6T according to a traveling speed of a terminal. As a result of this compensation, channel prediction error is reduced. And accordingly more accurate channel compensation is performed.Type: GrantFiled: December 30, 2002Date of Patent: June 6, 2006Assignee: LG Electronics Inc.Inventors: Tan-Joong Park, Hun-Geun Song
