Da shan Shiu, Durga P Malladi: Scheduling techniques for a packet-access network. D Scott Juneau, January 26, 2010: US07653028 (5 worldwide citation)

Multiple access interference may be substantially removed by introducing a near-far situation in which a near mobile and a far mobile (“near” and “far” based on signal strength) are selected, resources allocated among these and other mobiles, and the data is packetized for transmission during a tran ...

Da shan Shiu, Durga P Malladi, Srikrishna Bhashyam: Noise and channel estimation using low spreading factors. Qualcomm Incorporated, Thomas R Rouse, Charles D Brown, Milan I Patel, August 7, 2007: US07254170 (2 worldwide citation)

Noise measurements are made within a fraction of a single symbol period of a longest orthogonal code symbol. A control processor identifies an unoccupied code having a spreading factor that is less than a longest spreading factor for the system. A despreader measures symbol energy based on the unocc ...

Da shan Shiu, Iwen Yao: Buffer architecture for a turbo decoder. Qualcomm Incorporated, Philip Wadsworth, Kent D Baker, S Hossain Beladi, May 21, 2002: US06392572 (83 worldwide citation)

A buffer structure for storing intermediate results (i.e., APP data) for a Turbo decoder to increase access throughput, the buffer structure is designed to support concurrent access of APP data for two or more bits for each access cycle. This is achieved by partitioning the buffer into a number of b ...

Da shan Shiu, Serge Willenegger, Richard Chi, Parvathanathan Subrahmanya, Chih Ping Hsu: Power control for a channel with multiple formats in a communication system. Qualcomm Incorporated, Philip R Wadsworth, Thien T Nguyen, January 3, 2006: US06983166 (59 worldwide citation)

Techniques to more efficiently control the transmit power for a data transmission that uses a number of formats (e.g., rates, transport formats). Different formats for a given data channel (e.g., transport channel) may require different target SNIRs to achieved a particular BLER. In one aspect, indi ...

Da Shan Shiu, Avneesh Agrawal: Data buffer structure for physical and transport channels in a CDMA system. Qualcomm, Philip R Wadsworth, Charles D Brown, Kenyon S Jenckes, March 6, 2007: US07187708 (22 worldwide citation)

A buffer structure for storing symbols received via a number of (e.g., physical or transport) channels. Each channel is associated with a particular time interval (e.g., a radio frame period or a transmission time interval (TTI)) over which the received symbols are processed (e.g., interleaved). The ...
