  • Patent number: 7359313
    Abstract: A system employs space-time coding characterized at the transmitter by bit-interleaved coded modulation (BICM) combined with multi-carrier Orthogonal Frequency Division Multiplexing (OFDM) modulation. Space-Time coding techniques improve transmission efficiency in radio channels by using multiple transmit and/or receive antennas and coordination of the signaling over these antennas. Bit-interleaved coded modulation provides good diversity gain with higher-order modulation schemes that employ binary convolutional codes. OFDM modulation allows for wideband transmission over frequency selective radio channels. A receiver demodulates the OFDM signal and applies multi-input, multi-output (MIMO) demapping to estimate the BICM encoded bitstream. After deinterleaving of the BICM encoded bitstream, maximum a posteriori (MAP) decoding is applied to the resulting bit stream to generate soft output values.

  • Patent number: 7095812
    Abstract: A system employs space-time coding characterized at the transmitter by bit-interleaved coded modulation (BICM) combined with modulating several streams of the BICM encoded data for transmission over two or more antennas. Space-time coding techniques improve transmission efficiency in radio channels by using multiple transmit and/or receive antennas and coordination of the signaling over these antennas. Bit-interleaved coded modulation provides good diversity gain with higher-order modulation schemes that employ binary convolutional codes. A receiver demodulates the received signals and applies multi-input, multi-output (MIMO) demapping to estimate the BICM encoded bitstream. After deinterleaving of the BICM encoded bitstream, maximum a posteriori (MAP) decoding is applied to the resulting bit stream to generate soft output values. By applying well-known turbo-decoding principles to iteratively demap and decode, the overall receiver performance is significantly improved.

  • Patent number: 6961432
    Abstract: In a digital audio broadcast system, to utilize transmission bandwidth efficiently, representations of a stereo audio signal for transmission are generated in accordance with an inventive multidescriptive coding technique. The representations, as generated, are then transmitted through multiple communication channels, respectively. The transmitted representations are received by a receiver where one or more of the representations are selected for recovery of the stereo audio signal. Because of the design of the multidescriptive coding used, the more representations are selected to recover the stereo audio signal, the higher the quality of the recovered signal.

  • Patent number: 6931372
    Abstract: The invention provides methods and apparatus for processing information, e.g., audio, video or image information, for transmission in a communication system. In an illustrative embodiment, a joint multiple program coder determines the value of a single-bit or multiple-bit criticality measure, e.g., criticality flag, in a designated interval, e.g., the duration of an audio frame, for each of the programs in a set of multiple programs to be transmitted in the system. The joint multiple program coder allocates a pool of available bits to the programs based at least in part on the determined values of the criticality measures, such that a program with a higher-valued criticality measure in the designated time interval is allocated a greater percentage of the available bits for that interval than another one of the programs with a lower-valued criticality measure. The joint multiple program coder repeats the determination and allocation operations for each of a number of time intervals, e.g.

  • Patent number: 6874115
    Abstract: Techniques are disclosed for processing received information in a communication system, such that performance is significantly improved in the presence of certain types of interference, e.g., partial-band interference. In an illustrative embodiment, first and second digital sidebands are transmitted on either side of an AM or FM host carrier signal in a hybrid in-band on-channel (HIBOC) digital audio broadcasting (DAB) system. The compressed digital audio information in the sidebands is encoded using an error correcting code such as a Reed-Solomon (RS) code. A receiver attempts to detect interference within a designated portion of a given one of the sidebands. If the interference is detected, the receiver eliminates the portion of the frequency band from consideration in the decoding process by using a fixed-erasure decoding (FED) technique to decode the error correcting code.

  • Patent number: 6768778
    Abstract: The invention provides optimal complementary punctured convolutional codes for coding information bits in a communication system. In an illustrative embodiment, an optimal pair of complementary punctured codes is selected from a set of potential code pairs. The set of potential code pairs includes all non-catastrophic complementary punctured code pairs which combine to produce to a specified full-bandwidth code, and thus includes both equivalent and non-equivalent complementary codes. The optimal code pair may be selected, for example, as the pair of equivalent or non-equivalent codes which has the best free Hamming distance and minimum information error weight of all the pairs in the set. In addition, the invention provides both rate-compatible and rate-incompatible codes suitable for use in providing unequal error protection (UEP) for different classes of information bits.

  • Patent number: 6728924
    Abstract: A method for providing packet loss recovery in a data packet-based network used for real-time multimedia communications. In accordance with a first illustrative embodiment of the present invention, the information payload associated with a given data packet k is identically copied and appended to data packet k+w (i.e., the information payload is repeated with a delay of w transmitted packets). More generally, the present invention provides a method of coding a sequence of data packets representing a contiguous stream of information, with each data packet comprising, a set of payload information representative of a segment of the stream of information corresponding thereto.

  • Patent number: 6694474
    Abstract: Source-coded information from a multi-mode source encoder is channel coded for transmission in a communication system. A multi-mode channel encoder associates a different channel coding error protection profile with each of the modes of the multi-mode source encoder. The channel encoder determines a mode used by the multi-mode source encoder to source code a given frame or other designated portion of the information, and channel codes the source-coded portion of the information utilizing an error protection profile identified at least in part based on the determined mode. A multi-mode channel decoder is operative to hypothesize that a particular one of the modes of the multi-mode source encoder was used to source code the designated portion of the information.

  • Patent number: 6684367
    Abstract: Digital information is processed for transmission in a communication system using a hidden puncturing technique. The digital information is encoded using a channel code having at least one puncturing pattern associated therewith. The puncturing pattern is preferably a rate compatible puncturing pattern. In accordance with the invention, there is no puncturing of the channel code applied at a transmitter side of the system. Instead, the resulting channel coded bits are assigned to different sections of a digital sideband or other portion of a frequency spectrum of the system, based at least in part on the puncturing pattern. The coded channel bits are then transmitted through the system in the assigned sections, and can be decoded at different code rates in a receiver of the system depending on which of the sections are used in the decoding process.
