  • Patent number: 8352847
    Abstract: In one embodiment, a matrix-vector multiplication (MVM) component generates a product vector based on (i) an input matrix and (ii) an input vector. The MVM component has a permuter, memory, and an XOR gate array. The permuter permutates, for each input sub-vector of the input vector, the input sub-vector based on a set of permutation coefficients to generate a set of permuted input sub-vectors. The memory stores a set of intermediate product sub-vectors corresponding to the product vector. The XOR gate array performs, for each input sub-vector, exclusive disjunction on (i) the set of permuted input sub-vectors and (ii) the set of intermediate product sub-vectors to update the set of intermediate product subvectors, such that all of the intermediate product sub-vectors in the set are updated based on a current input sub-vector before updating any of the intermediate product sub-vectors in the set based on a subsequent input sub-vector.

  • Patent number: 8352830
    Abstract: In one embodiment, a method for processing data packets having a payload and a checksum, wherein the payload has a first portion of interest. If a received data packet fails a CRC check, then it is determined whether the first portion has a valid relationship with one or more previous first portions of one or more corresponding previous payloads of one or more corresponding previous data packets. If the relationship is valid, then the first portion is output. The method enables recovery of first portions of interest from corrupted data packets having transmission errors in other parts of the data packets, thereby potentially decreasing retransmissions and increasing throughput.

  • Patent number: 8352714
    Abstract: A processor (e.g., a Digital Signal Processor (DSP) core) rewinds a pipeline of instructions upon a watchpoint event in an instruction being processed. The program execution ceases at the instruction in which the watchpoint event occurred, while the instruction and subsequent instructions are cancelled, keeping the hardware components associated with executing the program in their previous states, prior to the watchpoint. The rewind is such that the program is refetched to enable execution to continue from the instruction in which the watchpoint event occurred. The watchpoint event is executed in a “break before make” manner.

  • Patent number: 8351520
    Abstract: In one embodiment, an algorithm dynamically selects a method for reducing distortion in a multi-carrier modulated signal, such as an orthogonal frequency division multiplexing (OFDM) signal. The algorithm directs a transmitter to transmit peak-to-average power ratio (PAPR)-reduction signals over reserved tones (i.e., frequencies) if reserved tones are available. If reserved tones are not available, then the algorithm directs the transmitter to transmit PAPR-reduction symbols over free tones if free tones are available. If the free tones for this transmitter are used by adjacent transmitters, then interference-reduction techniques may be used to reduce interference with the adjacent transmitters. If reserved tones and free tones are not available, then the transmitter may use an alternative method to reduce distortion, such as successive clipping and filtering. In another embodiment, the transmitter may transmit PAPR-reduction symbols over both free and reserved tones, if available.

  • Patent number: 8335542
    Abstract: A wireless transmission system supporting at least first and second high-isolation transmission modes. In the first TX mode, first and second incoming data streams are processed independently within first and second TX paths to generate first and second analog outgoing signals for separate transmission via first and second antennas. In the second TX mode, the two incoming data streams are combined to form a combined data stream. First and second versions of the combined data stream are processed by the first and second TX paths to generate two analog signals that are combined for transmission via a single antenna. In the second TX mode, a feedback signal, based on differences between the two analog signals, is used to adjust the relative phase and/or delay of the two versions of the combined signal in the digital domain to reduce phase differences between the two analog signals, thereby increasing signal transmission power.

  • Patent number: 8331552
    Abstract: In one embodiment, the presence of double talk (DT) is detected in a telecommunications network having a near-end user and a far-end user. The energies of both (1) a signal received from the far-end user by the near-end user and (2) a signal to be communicated from the near-end user to the far-end user are computed. An echo return loss (ERL) estimate is calculated based on the energy calculations, and a preliminary decision is made as to whether DT is present based on the ERL estimate and the energy calculations. If DT is detected, then a counter is set to a hangover value. If DT is not detected, then the counter is reduced. This process is repeated, and, for each iteration, a final decision as to whether DT is present is made based on the counter value.

  • Patent number: 8331217
    Abstract: A ground- or roof-top-based repeater in an OFDM system uses multiple transmission antennas to transmit multiple identical OFDM signals. Dithering is performed by introducing a slight variable-frequency phase offset to all but one of the multiple identical transmitted OFDM signals. The effective overall channel is more dynamic and provides spatial diversity to minimize long periods of fading in fading subchannels of the OFDM signals when the receiver is in a slow moving or stationary situation. To overcome the additional cancellation problem that can occur when two or more of the transmitting antennas are (i) in a line-of-site position with the receiver and (ii) approximately the same distance from the receiver, a delay is deliberately introduced to make the delayed signals appear to be reflected signals. This delay will not negatively impact the OFDM receiver performance as long as the delay is within the guard interval used in the OFDM process.

  • Patent number: 8332528
    Abstract: A communication system that enables a specified end-user device to obtain a media file corresponding to a delayed-play entry of a content-definition table prior to the scheduled play time. To deliver the media file to the end user, a service provider requests and receives the corresponding content from a content provider, generates the media file based on the received content, and temporarily stores the media file in a storage unit associated with the service provider. The service provider then breaks the media file into a plurality of data frames and transmits them to the end-user device during an appropriate delivery-opportunity window for storage in local storage unit (e.g., a hard drive) associated with the end-user device. At the play time, the service provider transmits to the end-user device a media-activation packet to initiate rendering thereat a copy of the media file assembled from the data frames stored in the local storage unit.

  • Patent number: 8327235
    Abstract: In one embodiment, an LDPC decoder has one or more reconfigurable adders that generate variable-node messages and one or more reconfigurable check-node units (CNUs) that generate check-node messages. The LDPC decoder has a five-bit precision mode in which the reconfigurable adders and CNUs are configured to process five-bit variable-node and check-node messages, respectively. If the LDPC decoder is unable to properly decode codewords in five-bit precision mode, then the decoder can be reconfigured in real time into a ten-bit precision mode in which the reconfigurable adders and CNUs are configured to process ten-bit variable-node and check-node messages, respectively. By increasing the size of the variable-node and check-node messages from five bits to ten bits, the probability that the LDPC decoder will decode the codeword correctly may be increased.
