Signal modulation method resistant to echo reflections and frequency offsets
ActiveUS9083595B2Improve performancePromote decompositionNetwork traffic/resource managementMulti-frequency code systemsHigh rateEngineering
A method of modulating communications signals, such as optical fiber, wired electronic, or wireless signals in a manner that facilitates automatic correction for the signal distortion effects of echoes and frequency shifts, while still allowing high rates of data transmission. Data symbols intended for transmission are distributed into N×N matrices, and used to weigh or modulate a family of cyclically time shifted and cyclically frequency shifted waveforms. Although these waveforms may then be distorted during transmission, their basic cyclic time and frequency repeating structure facilitates use of improved receivers with deconvolution devices that can utilize the repeating patterns to correct for these distortions. The various waveforms may be sent in N time blocks at various time spacing and frequency spacing combinations in a manner that can allow interleaving of blocks from different transmitters. Applications to channel sounding / characterization, system optimization, and also radar are also discussed.

Method and apparatus for mobile station management and system
ActiveUS20060128371A1Radio/inductive link selection arrangementsTransmission monitoringAccess networkCommunications system
A communication system optimizes system performance by selectively managing which mobile stations (MSs) are to serve as test MSs. The test MSs report system operating parameters in order to detect sleeping cells, coverage holes, or other flaws in system coverage or in order to determine an impact of a change in an access network configuration. The communication system further provides for end-to-end messaging between the test MSs and network servers via an access network and a core network, thereby permitting network elements that are best able to perform system optimization to control the monitoring, measuring, and reporting by the MSs. To minimize system and user inconvenience, reporting by a test MS further may be based on one or more of whether the MS is in an area of low mobility, has an acceptable power source output level, and is operating in a cell with an acceptable load level.

To maintain the integrity and operability of enterprise database systems, queries intended for a particular database engine are intercepted, preferably by a separate processing system, prior to being acted upon by the database engine. The query is evaluated to determine its projected impact on available database system resources. The variables evaluated include user rights, administrator-imposed limits to searches, the amount of presently-available system resources, the cost of query and the like. If the query's potential impact does not surpass a predetermined threshold, it is submitted to the search engine.

System and method for dynamically allocating associative resources
InactiveUS20040078532A1Easy to useLower levelResource allocationMemory adressing/allocation/relocationSystem optimizationDistributed computing
A method and structure for balancing associative resource (e.g., cache lines or buffers) allocation with respect to load, wherein said resources are allocated / deallocated to requesting processes or "agents" based on their reference history and demand. User agents that fail to meet minimum use criteria, are forced to relinquish logically allocated resources to high demand agents. Otherwise, an agent maintains control of its resources in the presence of other high demand agents, without cross-agent thrashing for resources. An associative resource "pool" is logically divided into m partitions. A small "partition reference" counter is employed for each partition to record its usage history. A global "persistence reference" counter functions to erase the "set reference" counter history at a programmable rate. Low "partition reference" counter values imply low usage, and make partition resources available to high usage partition(s) when needed. Programmable thresholds permit "weighting" the criteria for system optimization.
