Patent number: 7933371Abstract: Method and Apparatus for controlling combining coefficients of multiple receive antennas according to the channel conditions in a mobile communication system, to improve data restoration performance. A mobile station detects preamble, pilot and data from a signal received from a base station via the multiple receive antennas, measures a channel correlation from the detected preamble, classifies time-domain/frequency-domain intervals having a channel correlation exceeding a predetermined threshold as calculation regions, and calculates MMSE coefficients for the calculation regions. In this way, the mobile station finds the optimal coefficients for combining the signal received via the multiple receive antennas, thereby optimizing the reception performance.Type: GrantFiled: November 27, 2007Date of Patent: April 26, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Huigiang Zhou, Jong-Hun Rhee, Min-Goo Kim, Sung-Soo Kim

Patent number: 7801103Abstract: A method and apparatus provide a broadcast parameter message in a mobile communication system providing a broadcast service. If the provided broadcast service is time domain multiplex (TDM)-multiplexed, a message generator generates the broadcast parameter message by setting a field indicating the TDM multiplexing, setting a field indicating a position of the broadcast service in each sub-buffer, setting a field indicating whether one sub-buffer includes one service and a field indicating validity of the field, and setting a field exclusively indicating actual broadcast service data stored in one sub-buffer.

Patent number: 7539928Abstract: A method and apparatus for decoding inner and/or outer codes in a mobile communication system. The inner and/or outer codes are decoded at low power and high speed. An inner decoder performs channel decoding and cyclic redundancy checking (CRC) on symbols received through a wireless network. An outer decoder performs outer coding on the received symbols. An erasure symbol identifier outputs information of erasure symbols in which a reception error has occurred. The reception error is determined from a result of the CRC on the received symbols. A controller counts the number of received symbols and the number of erasure symbols, and stops an operation of at least one of the inner and outer decoders when at least one of the number of received symbols and the number of erasure symbols is equal to a preset reference value.Type: GrantFiled: May 31, 2005Date of Patent: May 26, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Jong-Hun Rhee, Su-Yean Kim, Min-Goo Kim
