  • Publication number: 20090077447
    Abstract: A wireless communication device (200) including a first CRC coder that generates a first block of CRC parity bits on a transport block and associates the first block of CRC parity bits with the transport block, a segmenting entity that segments the transport blocks into multiple code blocks after associating, and a second coder that generates a second block of CRC parity bits on each code block and associates a second block of CRC parity bits with each code block. The first and second blocks of CRC parity bits are based on first and second generator polynomials. In one embodiment, the first and second generator polynomials are different. In another embodiment, the generator polynomials are the same and the transport block is interleaved before segmenting or the code block are interleaved before encoding with the second block of CRC parity bits.

  • Patent number: 7493298
    Abstract: A method for efficiently engineering large, complex systems is provided. The method uses a uniquely defined decision model to lead the design effort by structuring and analyzing decision making needs of the people who will use the system before any design efforts can constrain the solution. While other methods may suffice for incremental system developments, i.e., system developments where small improvements over legacy systems are the objective, this method is particularly useful where revolutionary system improvements, or wholly new system developments is the objective.

  • Publication number: 20080316995
    Abstract: The present invention provides a broadcast channel signal and apparatus for managing the transmission and receipt of broadcast channel information, where a known difference in the data prior to encoding for transmission produces a predictable difference, which can be removed or cancelled from the multiple received active frames, such that their differences can be negated prior to combining and subsequently decoding. In at least one embodiment one or more applied linear encoding techniques can allow for a predictable difference in the encoded values based upon a knowledge of the difference prior to encoding.

  • Publication number: 20080320527
    Abstract: The present invention provides a method for transmitting broadcast channel information as part of a broadcast channel signal having one or more transmission intervals, where each transmission interval includes a plurality of transmissions, and one or more of the transmissions are active frames in which broadcast channel information is transmitted. Invariant portions that are present in the broadcast channel information are identified separate from any variant portions and are encoded for transmission, and the variant portions are used to select transmission specific configurations, which can be detected during the decoding by the receiver. Upon detection of the transmission specific configuration used to encode the invariant portions, the value of the variant portion can be identified and reintroduced as part of the received broadcast channel information.

  • Publication number: 20080279312
    Abstract: A method and apparatus for jointly decoding a first and second message is disclosed. The signaling scenario illustrated by FIG. 1 and using the codeword properties defined herein, the various embodiments may combine multiple messages under the hypothesis that the value of a message portion corresponding any subsequent observed transmission is different. Accordingly a first buffer may store the first observed message frame (509) and a second buffer may sum the LLR's of subsequent observed frames (513). In the embodiments disclosed, two decoding hypotheses are required only; a first where the two buffers are combined directly (513) and a second where the difference codeword bit LLR's of the first buffer (509) are inverted before combining with those of the second buffer (519). A maximum of N transmissions is allowed by the receiver (523), after which a decoding failure is declared.

  • Patent number: 7000173
    Abstract: An improved turbo code based incremental redundancy includes a first step of puncturing a data stream for a first transmission to provide a set of first unpunctured trellis sections. A next step includes puncturing a data stream for a second transmission to provide a set of second unpunctured trellis sections. A next step includes incremental redundancy combining the first and second transmissions of the trellises to provide non-adjacent first and second unpunctured trellis sections. The above arrangement results in a uniform distribution of punctured and unpunctured bits to provide lower errors.
