Division circuits that are not used may be disabled to reduce power consumption. At another stage of the decoding process where the decoder generates coefficients that are used to identify locations of errors in the codeword, the decoding process can limit power consumption by reducing the number of iterations of a polynomial generator by incorporating termination decision circuitry. | 2011-05-05 |
| 20110107189 | APPARATUS AND METHOD FOR TRANSMITTING DATA IN COMMUNICATION SYSTEM - An apparatus for transmitting data in a communication system includes: a first repeater configured to repeat information bits of data to be transmitted a first repetition number of times; an interleaver configured to interleave the information bits repeated the first repetition number of times; an accumulator configured to accumulate-code the interleaved information bits; a second repeater configured to repeat the accumulate-coded information bits a second repetition number of times; a puncturer configured to puncture the information bits repeated the second repetition number of times; and a P/S converter configured to convert the punctured information bits and the information bits of the data and output RA-coded information bits. | 2011-05-05 |
| 20110107190 | OBSCURING INFORMATION IN MESSAGES USING COMPRESSION WITH SITE-SPECIFIC PREBUILT DICTIONARY - Obscuring information in messages to be exchanged over a communications network. In one aspect, the information comprises path name information and parameters for use in a Uniform Resource Locator (“URL”). In another aspect, the information comprises links and parameters used in forms, where hidden parameters are removed from a form and used as URL parameters. A compression dictionary is used to create a compressed form of the information. An identifier of the dictionary and an error detection code (such as a checksum) computed over the compressed information are concatenated with the compressed information, and this is encoded for sending on an outbound message. The original information is then recovered from an inbound message which contains the obscured information by reversing the processing used for the obscuring. | 2011-05-05 |
| 20110107191 | Method of detecting error in a semiconductor memory device - A semiconductor memory device and a memory system including the same are provided. The semiconductor memory device may include a first memory cell array block generating first data, a second memory cell array block generating second data, and first and second error detection code generators. The first error detection code generator may generate a first error detection code and may combine a portion of bits of the first error detection code with a portion of bits of a second error detection code to generate a first final error detection signal. The second error detection code generator may generate the second error detection code and may combine the remaining bits other than the portion of bits of the second error detection code with the remaining bits other than the portion of bits of the first error detection code to generate a second final error detection signal. | 2011-05-05 |
| 20110107192 | Authoring Tool and Method for Creating an Electrical Document - An authoring tool for creating an electronic document, a method for creating the electronic document, a data storage medium for instructing a computer to execute the method for creating the electronic document and a data storage medium for instructing a computer to display the electronic document. The authoring tool comprises; a template module for selecting a template for the electronic document, the template comprising one or more display pages; a content management module for arranging one or more media files on each display page with selected interrelationships between the media files; a generating module for creating an electronic page file for each display page, wherein the media files are embedded in the respective electronic page files based on the selected interrelationships and in a manner such that each electronic page file includes interrelationship data defining the interrelationships of the embedded media files in said each electronic page file with other media files in said each electronic page file and with other media files in other electronic page files of the electronic document; and a binding module for electronically binding the respective electronic page files so as to create the electronic document. | 2011-05-05 |
