    Abstract: A communication system is provided with a reconfigurable hardware structure to provide implementation flexibility while minimizing a reduction in low power consumption performance. The communication system includes a plurality of processing element (PE) blocks for processing data based on multiple wireless transmission standards, memories for storing data being processed or to be processed by the PE blocks, and a controller for controlling data processing in the PE blocks, a data input operation to the PE blocks and a data output operation from the PE blocks, and for controlling transmission of data being processed in and input/output to/from the PE blocks. Each of the PE blocks includes a plurality of PE modules, and each of the PE modules includes a predetermined number of PEs that perform different functions. Operation and input/output of the PE blocks, the PE modules and the PEs are controlled by the controller.

    Abstract: A rake receiver for high data rate communications systems is provided that is able to share resources between demodulating branches without using independent hardware resources for each finger. The rake receiver of the present invention uses less circuitry while keeping functional equivalence, and it requires relatively smaller additional area when increasing the number of demodulating branches, thereby having a significantly smaller size, being able to track more demodulating paths for increasing performance, and being less complex as compared to conventional rake receivers for high data rate communications systems.

    Abstract: Broadband, ultra wideband and ultra narrowband (UWN) reconfigurable, interoperable communication and broadcasting system architectures, combinations and hybrids of ultra wideband (UWB), ultra narrowband (UNB) and efficient broadband wireless, baseband, intermediate frequency (IF) and radio frequency (RF) implementations for Bit Rate Agile (BRA) reconfigurable and interoperable systems, Adaptive Modulation and Coding (AMC). Processing the data signals, of clock signals, and/or carrier cycles waveforms leads to shaped radio-frequency (RF) cycles, waveforms and wavelets. With Multiple Input Multiple Output (MIMO) diversity and protection system configuration the performance and capacity of these systems may be further enhanced.

    Abstract: In order to perform, according to a received signal (r), a channel-estimation procedure and a cell-search procedure in cellular communication systems, there are executed at least one first operation of correlation of said received signal (r) with secondary synchronization codes (SSC) and a second operation of correlation of said received signal (r) with known midamble codes (mid, MPL, MPS), whilst said channel-estimation procedure comprises a third operation of correlation of at least part of said received signal (r) with known midamble codes (mid, MPL, MPS), said first, second, and third correlation operation being executed by sending at least part (emidamble) of said received signal (r) to an input of a correlation bank. There are envisaged the operations of: sending, in a first time interval, the received signal (r) to said correlation bank for executing the first operation of correlation of said received signal (r) with secondary synchronization codes (SSC); sending, in a second time interval, at least part (emidamble) of said received signal (r) to said same correlation bank for executing the second operation of correlation of said received signal (r) with known midamble codes (mid, MPL, MPS); sending, in a second time interval, the received signal (r) to said same correlation bank for executing the third operation of correlation of at least part (emidamble) of said received signal (r) with known midamble codes (mid, MPL, MPS). Possible application is in mobile communication systems based upon standards such as UMTS, CDMA2000, IS95 or WBCDMA.

    Abstract: Improved apparatus for a radio communication network having a multiplicity of mobile transceiver units selectively in communication with a plurality of base transceiver units which communicate with one or two host computers for storage and manipulation of data collected by bar code scanners or other collection means associated with the mobile transceiver units. The radio network is adaptive in that in order to compensate for the wide range of operating conditions a set of variable network parameters are exchanged between transceivers in the network. These parameters define optimized communication on the network under current network conditions. Examples of such parameters include: the length and frequency of the spreading code in direct-sequence spread spectrum communications; the hop frame length, coding, and interleaving in frequency-hopping spread spectrum communications; the method of source encoding used; and the data packet size in a network using data segmentation. The invention is preferably to be applicable as an upgrade of an existing data capture system wherein a large number of hand-held transceiver units operate over an extensive area to gather data in various places, requiring the use of multiple base stations. In a variety of such installations such as warehouse facilities, distribution centers, and retail establishments, it may be advantageous to utilize not only multiple bases capable of communication with a single host, but with multiple hosts as well.

    Abstract: An apparatus and method for adjusting a desired expression section according to input bit values in a mobile communication system that expresses only a defined partial section of the input bit values in order to make the number of output bits be less than the number of the input bits, and maps bit values included in unexpressed sections to a specific value is provided. In the apparatus and method, a measurer divides possible output bit values into at least three sections, and measures output frequencies of output bits for the respective sections for a predetermined time. A controller adjusts the desired expression section, when an output frequency for a specific section is greater than output frequencies for other sections.
