20080240305Message Decoding With Apriori Information and Soft Combining - A method and arrangement for improving channel decoding performance in a radio receiver. Data bits from previously decoded messages are analyzed to provide a priori information to a channel decoder which is decoding a currently received message of the same type.

20120123984OPTIMAL PERSISTENCE OF A BUSINESS PROCESS - Embodiments of the invention provide for automatically selecting optimal fetch settings for business processes as a function of database query load and relational context by determining whether data loaded for data retrieval points is dependent upon a query result from another query process and automatically selecting an eager fetch setting if dependent upon a query result from another query process, or a lazy fetch setting if not. Usage of the data retrieval points is monitored with respect to defined units of work to define retrieval patterns and automatically update the fetch settings, including by revising selected eager fetch settings to lazy fetch settings if a datasize of a defined retrieval pattern is larger than a permissible memory resource threshold.05-17-2012
20120136907VIRTUAL NODE SUBPOOL MANAGEMENT - Virtual file system virtual nodes are grouped in subpools in response to identified resource components and managed as a function of their subpool groupings. Virtual nodes are decomposed into individual components linked to each other within each node. The components that have repetitive accesses by applications within the virtual file system and their respective frequencies of repetitive access are identified. Modules of linked occurrences of the repetitive components within each of the plurality of virtual nodes are formed, and subsets of the virtual nodes sharing common modules are grouped into subpools. Accordingly, in response to an application of the virtual file system requesting a service that is satisfied by a subpool common module, selection of a virtual node for reinitiating for reuse by the application is restricted to virtual nodes within the subpool associated with the common module.05-31-2012

20110064043SYSTEM, METHOD, AND APPARATUS FOR IMPROVED SPACE-TIME CODING AND DYNAMIC SWITCHING WITH ADVANCED RECEIVERS - Methods and apparatus for allocating time-frequency resources to mobile terminals in a wireless communications system in which time-frequency resources may be selectively used according to a first multiple-input multiple-output (MIMO) transmission scheme or a second MIMO transmission scheme that differs from the first MIMO transmission scheme. An exemplary method comprises, for at least a first scheduling instance, identifying a first group of mobile terminals corresponding to the first MIMO transmission scheme and a second group of mobile terminals corresponding to the second MIMO transmission scheme, allocating time-frequency resources in a first pre-determined time-frequency zone exclusively to mobile terminals belonging to the first group, and allocating time-frequency resources in one or more additional pre-determined time-frequency zones to one or more mobile terminals belonging to the second group. This method may be implemented in a base station of a WiMAX system, for example.03-17-2011
