    摘要: A system and method are provided for optimizing component composition in a distributed stream-processing environment having a plurality of nodes capable of being associated with one or more of a plurality of stream processing components. The system includes an adaptive composition probing (ACP) module and a hierarchical state manager. The ACP module probes a subset of the plurality of stream processing components to determine the optimal component composition in response to a stream processing request. The hierarchical state manager manages local and global information for use by said ACP module in determining the optimal component composition.

    摘要: A system and method for optimizing program code in dynamic languages includes gathering hot-type information from a program by employing inferencing or profiling to get the hot-type information for operator uses, and inserting guards in the program based on data flow in the program to guard against propagation failures during runtime where preconditions are violated or where the propagation is unlikely to return. The program is versioned into global versions including a hot path version and a cold path version, where the hot path version is expected to be executed if the values of variables in the code are expected types, and other exceptional cases are handled by the cold path version as triggered by the guards. Compiler optimizations are performed to remove redundant representations of values, and heavy overloading of operators to provide an optimized compiling of the code.

    摘要: Disclosed is a method for decoding received signals on communication channels between at least one transmit antenna and plural receive antennas in a space-time coded direct sequence (DS)-CDMA communication system. The decoding method includes steps of: adjusting the step-size which is an update unit for the tap weight vector for despreading received signals; updating the tap weight vector using the step-size; and despreading the received signals using the tap weight vector. According to the decoding method, the optimal performance can be achieved because the tap weight vector and the step-size are adaptively updated according to changes of communication environment. Such superior performance is more remarkable as the number of receive antennas and transmit antennas increases.
