    摘要: A method for channel estimation, includes receiving an input signal due to a superposition of waveforms encoding symbols transmitted respectively by a plurality of transmitters in a common frequency band. Each transmitter among the plurality of transmitters modulates the symbols with a respective spreading code. The input signal is sampled at sampling intervals over the duration of an observation period, thus providing a sequence of samples. The sequence of complex samples is processed to estimate a channel response for each of the transmitters by maximizing, individually for each of the transmitters and based on the respective spreading code of the transmitter, a likelihood of correctly decoding the transmitted symbols using the estimated channel response.

    摘要: An apparatus and method are provided for updating one or more pluralities of pointers (i.e. one or more vector pointers) which are used for accessing one or more pluralities of data elements (i.e. one or more vector data elements) in a multi-ported memory. A first register file holds the vector pointers, a second register file holds stride data, and a plurality of functional units combine data from the second register file with data from the first register file. The results of combining the data are transferred to the first register file and represent updated vector pointers. Furthermore, a third register file is provided for holding modulus selector data to specify the size of a circular buffer for circular addressing.

    摘要: A digital signal processor (DSP) includes a SIMD-based organization wherein operations are executed on a plurality of single-instruction multiple data (SIMD) datapaths or stages connected in cascade. The functionality and data values at each stage may be different, including a different width (e.g., a different number of bits per value) in each stage. The operands and destination for data in a computational datapath are selected indirectly through vector pointer registers in a vector pointers datapath. Each vector pointer register contains a plurality of pointers into a register file of a computational datapath.

    摘要: Systems and methods for detecting end of a transaction in a computing environment are provided. The method comprises determining a target area in a graphical user environment displayed on a display screen, wherein a change is expected to occur when end of a transaction is reached; masking the target area at least partially to remove content included in the target area that is present before or after the transaction was initiated; monitoring the target area for change in content; and detecting the end of the transaction when the content of the target area has changed.

    摘要: A computer-implemented method for processing paper forms includes capturing at a computer system an image of a paper form in which information has been filled-in. A location identifier is extracted from the image. The location identifier indicates an address in a storage location external to the computer system, at which the filled-in information is electronically stored. The information is retrieved responsively to the location identifier by communication with the storage location via a wide area network (WAN), so as to convey the information electronically from the storage location to the computer system. The information is processed using a data processing application running on the computer system.
