    摘要: A method of location positioning of a Radio Access Point (AP) is provided in an embodiment of the present invention. The method includes: querying the Connectivity Session Location and Repository Function (CLF) according to the IP address of the AP to obtain the Access Line Location Identifier (ALLI) of the AP to access a network. The ALLI is configured to identify the line location of the AP. The location of the AP is determined on the basis of the ALLI. A method of location verification of an AP is provided herein in an embodiment of the present invention. The method includes: the CLF is queried according to the IP address of the AP to obtain the ALLI of the AP; the location of the AP is not changed if the obtained ALLI of the AP is the same as the stored ALLI of the AP. A home register and a system are also provided herein to accurately locate and verify the location of the AP, thus checking the validity of the AP location.

    摘要: An adjacent channel interference rejection mechanism is provided to detect and reject CCK-modulated signals from an adjacent channel in a wireless communication receiver. Replicas of the baseband signals are frequency-shifted and then analyzed through a series of correlations to compare the power of the correlation outputs. An adjacent channel interference of a CCK-modulated signal is determined and rejected based on the comparisons meeting a predetermined tolerance level.

    摘要: Techniques are provided for estimating the cardinality of a virtual result table that is produced by executing path-based table functions within a query, such as the XMLTABLE function. Some path-based table functions apply a path expression to input from a base table of XML documents to select rows to produce the result table. Path statistics are collected for the path expressions for the base table. The path statistics are used to estimate the cardinalities of the result table. The estimated cardinality of the result table is useful for estimating costs of query execution plans that are generated for the query.

    摘要: A query is rewritten to combine streaming evaluation and XML index evaluation. The query is rewritten to include a streaming operator (e.g. function) that, when executed, uses streaming evaluation. Further, the query is rewritten so that XML index evaluation of a path expression also produces location information that identifies the location of a node within an XML document. The streaming operator is able to exploit the location information to begin and end scanning rather than scanning the entire XML document.

    摘要: In a multiple-input, multiple-output system, the frequency of transmitted signals can be partitioned into some number of frequency bins. During an exchange of sounding signals, a first station can monitor the quality of the signals to select a second station that is qualified to participate in a calibration procedure. The first station can generate a first set of channel characteristics for a particular frequency bin based on the sounding signal it receives from the second station. The first station also receives channel state information from the second station which can be used to generate a second set of channel characteristics for the particular frequency bin. Then, the selected subsets of the first and second sets can be manipulated in order to determine a set of correction values for that frequency bin as well as for other frequency bins.

    摘要: A wireless transmitter can include a plurality of bandwidth modules, each bandwidth module processing data based on a predetermined frequency band. In one embodiment, such a wireless transmitter can include encoding components for receiving transmit data and generating encoded data. A multiple-input multiple-output (MIMO) stream parser can receive the encoded data and generate a plurality of MIMO streams. A first module parser coupled to a first MIMO stream can generate a first plurality of partial MIMO streams. A first bandwidth module can include a first interleaver that interleaves bits of the first partial MIMO stream and generates first interleaved data. A second bandwidth module can include a second interleaver that interleaves bits of the second partial MIMO stream and generates second interleaved data. A first inverse fast Fourier transform (IFFT) unit can combine and process the first and second interleaved data and generate a first transmission MIMO stream.

    摘要: An AGC control unit coordinates AGC gain changes between individual receive chains included within a MIMO receiver block. Coordinated AGC gain changes reduce time periods of unaligned MIMO data produced by the receive chains. Reducing the unaligned data periods advantageously increases the time that the output data may be combined to improve overall performance of the receiver block. Coordinated AGC control also enables a faster response to saturated signals since the gain of multiple receive chains may be changed contemporaneously.

    摘要: Techniques for estimating the cost of processing a database statement that includes one or more path expressions are provided. One aspect of cost is I/O cost, or the cost of reading data from persistent storage into memory according to a particular streaming operator. Binary-encoded XML data is stored in association with a synopsis that summarizes the binary-encoded XML data. The synopsis includes skip length information for one or more elements and indicates, for each such element, how large (e.g., in bytes) the element is in storage. The skip length information of a particular element thus indicates how much data may be skipped during I/O if the particular element does not match the path expression that is input to the streaming operator. The skip length information of one or more elements is used to estimate the cost of processing the database statement.
