Abstract: A method of adaptive error correction coding includes processing data during a connection between a transmitting entity and a receiving entity, where the data is processed in accordance with a predetermined coding scheme. More particularly, processing data can include encoding one or more sequences received by an error correction encoder of the transmitting entity, or decoding one or more block codes received by an error correction decoder of the receiving entity. During the connection, then, the method can include selecting or receiving a selection of feedback code information. Thus, during at least a portion of the connection, the data processing can be switched to processing data in accordance with a parity-check coding technique based upon the feedback code information.

Each puncture sequence S i for a code rate R i is related to the puncture sequence S i-1 of the previous code rate R i-1 and preferably S 1 ⊆S 2 ⊆...⊆S max - 1 ⊆S max . The puncture sequences are groups of one or more memory elements, each of which is a variable degree, a variable node location, a check degree, or a check node location.

Abstract: An illustrative seismic while drilling system includes a drill string having at least one seismic sensor that can be employed to detect seismic signals during pauses in the drilling process, e.g., when extending the length of the drill string. An embedded processor digitizes a signal from the seismic sensor to obtain a digital waveform and processes the digital waveform to derive a compressed waveform representation for storage or transmission. Compression is provided by adaptively reducing the sampling rate and quantization resolution subject to one or more quality constraints including, e.g., error in first break timing, error in first break sign, mean square error, and bit count. Reasonably good representations of the received acoustic waveforms can be achieve with less than 200 bits.

Abstract: A system, transmitter, receiver, method, and computer program product are provided in which a plurality of structured interleavers permute data bits arranged in a data bit matrix for Zigzag encoding. For each interleaver, the data bits in each column of the data bit matrix are cyclically shifted, with the amount of the shift being predefined and different for each column. In addition to the cycle shift, each column may be bit reverse ordered, and entire columns may be swapped. The interleaved data bit matrix may then be encoded using a Zigzag encoder to generate parity bits that may be transmitted, along with the data bits, from a transmitter to a receiver where the data may be iteratively decoded.

Abstract: A method of constructing a puncture sequence includes providing a seed puncture sequence including a plurality of elements. The elements of the seed puncture sequence are based upon non-zero elements of a plurality of columns of a parity-check matrix having a column dimension and a row dimension. In this regard, the parity-check matrix defines an error correction code, and has been constructed based upon a seed parity-check matrix derived from an edge ensemble. After providing the seed puncture sequence, a variable node-puncture sequence can be constructed based thereupon. The variable node-puncture sequence, then, corresponds to a puncture sequence configured for processing an error correction code.
