Abstract: Multi-code LDPC (Low Density Parity Check) decoder. Multiple LDPC coded signals can be decoded using hardware provisioned for a minimum requirement needed to decode each of the multiple LDPC coded signals. In embodiments where each LDPC matrix (e.g., employed to decode each LDPC coded signal) includes a common number of non-null sub-matrices, then a same number of memories are employed when decoding each LDPC coded signal. However, those particular memories employed can be different subsets for when decoding each LDPC coded signal. In embodiments where each LDPC code includes a different number of non-null sub-matrices within its respective LDPC matrix, then a different number of memories are employed when decoding each LDPC coded signal. Various degrees of parallelism in decoding can also be employed in which different numbers of bit engines and check engines can be employed when decoding different LDPC coded signals.

The method continues by, for each of the two transmission paths, determining at least one of: level of constellation, number of data subcarriers, rate code, and cyclic prefix duration.

Abstract: Symbol by symbol MAP detection for signals corrupted by colored and/or signal dependent noise. A novel means is presented for recursive calculation of forward metrics (?), backward metrics (?), and corresponding soft information (e.g., which can be provided as LLRs (log likelihood ratios)) within communication systems in which a trellis can be employed to perform demodulation of a received signal sequence. For signals that have been corrupted by colored and/or signal dependent noise, this means provides for the ability to perform novel soft information calculation for subsequent use in iterative decoding processing. Many types of communication channels can benefit from this novel means of detection including communication channels within hard disk drives (HDDs).

Abstract: A diagnostic tool for identifying priority errors within a data network is realized using a priority trace data packet. The priority trace data packet is originated at an originating node of interest and terminated at a terminating node of interest. At various intermediate network nodes along the data path between the originating and terminating nodes, the priority trace packet is inspected to determine the current priority value of the priority trace packet. The current priority value is stored in a priority trace field that can be analyzed by a network management node to identify one or more sources of priority errors.

Abstract: A search operation can implement a two step approach to provide geographically restricted and verified information to a user. First, high relevance search results are obtained by searching only in a specifically defined region. Second, the quality of the search results can be improved by performing contact address correlation. If the search server finds a reliable reference address in the search results these search results can be presented to the user after removing-search results not correlating well with legitimate and registered addresses. Therefore, the region-restricted presents only presents legitimate web pages or search results to a user. Thus, the region-restricted search operation improves quality and may minimize search time and reduce a huge volume of non-valued Internet traffic, which is likely to impair the overall performance and experience on the Internet.

The double transformer balun design also includes a matching Z (impedance) block that is operable to match the Z of an antenna or line that the PA is driving.

Abstract: Fixed-spacing parity insertion for FEC (Forward Error Correction) codewords. Fixed spacing is employed to intersperse parity bits among information bits when generating a codeword. According to this fixed spacing, a same number of information bits is placed between each of the parity bits within the codeword. If desired, the order of the parity bits may be changed before they are placed into the codeword. Moreover, the order of the information bits may also be modified before they are placed into the codeword. The FEC encoding employed to generate the parity bits from the information bits can be any of a variety of codes include Reed-Solomon (RS) code, LDPC (Low Density Parity Check) code, turbo code, turbo trellis coded modulation (TTCM), or some other code providing FEC capabilities.
