摘要： A modem architecture that supports the application of joint source channel decoding (JSCD). The modem architecture includes two channel decoders, one of which is modified to provide improved signal quality. The modem architecture further includes transparent network layers that enable the passage of data from one layer to another layer. For example, the modem architecture enables the passage soft bits, when available, from a physical layer to an application layer. The soft bits may be utilized for JSCD, packet loss concealment, or other applications. The modem architecture enables encryption and decryption of data to incorporate extrinsic information in operating JSCD.

摘要： One aspect provides a method. The method comprises receiving a signal comprising a sequence of encoded symbols, each corresponding to one of a plurality of possible states. For each symbol in the sequence, the method further comprises determining a set of state metrics, each representing a probability that the respective symbol corresponds to the plurality of states. The method further comprises decoding the signal by processing runs of recursions using runs of forward recursions, whereby a later state metric in the sequence is updated based on a preceding state metric, and runs of recursions using runs of reverse recursions, whereby a preceding state metric in the sequence is updated based on a later state metric. The method further comprises outputting the decoded signal to a device. The decoding comprises performing a plurality of repeated iterations over the sequence.

摘要： A system and method for mapping and decoding codewords in acknowledgement information communications are provided. A method for communications device operations includes determining a hybrid automatic repeat request (HARQ) response for each component carrier (CC) in a set of configured CCs, thereby producing a set of HARQ responses, generating an information vector from the set of HARQ responses, encoding the information vector based on a (n, k) linear block code corresponding to the set of configured CCs, and transmitting the encoded information vector. A unique set of bits selected from the information vector is assigned to represent a HARQ response for each different CC in the set of configured CCs. The (n, k) linear block code is obtained by a linear transformation of an original (n, k) linear block code, where n is a length of code words, and k is a length of information vectors.

摘要： The receiver includes a signal determiner, a soft information determiner and a soft information decoder. The signal determiner determines a complex receive value for the receive signal received from a relay station. Further, the soft information determiner obtains a soft information represented by a combination of a first probability value and a second probability value. The first probability value is derivable by adding a value depending on an overall probability density function for each symbol of a modulation alphabet including a same first bit value at a same bit position of the symbols, wherein each symbol of the modulation alphabet represents at least two bits. Further, the overall probability density function indicates a probability of receiving the complex receive value, if a signal representing the respective symbol s considered for adding was transmitted from a transmitter to a relay station, wherein the signal representing the respective symbol causes the receive signal received from the relay station. The second probability value is derivable by adding a value depending on the overall probability density function for each symbol of the modulation alphabet including a same second bit value at the same bit position of the symbols. Further, the soft information decoder decodes payload data contained by the receive signal based on the obtained soft information.
