Abstract: A distributed storage network received a data segment. The data segment is partitioned into two or more portions. A first portion hash is calculated from the first portion of data and used to encrypt the second portion of data. A hash of the encrypted second portion of data is then used to either encrypt the next portion of data (in this case, a third portion of data) or to circle back to the beginning and encrypt the first portion of the data if the second portion of data is the last in data segment. This iterative process continues until all portions of the data segment are encrypted in a sequence. In essence, the data portions of the segment are sequentially processed in some order to encrypt the various portions in that progressing order. A reverse order is used to derive the hash values and decrypt the encrypted data portions into decrypted original data to recreate the data segment.

Abstract: A diagnostic tool is provided for calculating the availability of multi-segment pseudowires within an internet protocol (IP)-based mobile backhaul network. A control message is transmitted from an originating node towards a destination node within the IP-based mobile backhaul network over a primary multi-segment pseudowire and a secondary multi-segment pseudowire. From the response messages received from intermediate nodes positioned between the network node and the destination node along the primary multi-segment pseudowire and the secondary multi-segment psuedowire, the originating node determines the identities of each of the intermediate nodes, and calculates a respective individual availability of the primary multi-segment pseudowire and the secondary multi-segment pseudowire.

Abstract: Aspects of a method and system for utilizing tone grouping with Givens rotations to reduce overhead associated with explicit feedback information are presented. In one aspect of the invention, Givens matrices may be utilized to reduce a quantity of information communicated in explicit feedback information via an uplink RF channel. The explicit feedback information may include specifications for a feedback beamforming matrix that may be utilized when transmitting signals via a corresponding downlink RF channel. The feedback beamforming matrix may represent a rotated version of an un-rotated matrix. The Givens matrices may be utilized to apply one or more Givens rotations to un-rotated matrix. The rotated matrix may reduce the quantity of information communicated in the explicit feedback information. The quantity of information communicated in the explicit feedback information may be further reduced by utilizing tone grouping.

The receiving wireless device estimates a channel response based upon the preamble sequence and then determines an estimated transmitter beamforming unitary matrix based upon the channel response and a receiver beamforming unitary matrix. The receiving wireless device then decomposes the estimated transmitter beamforming unitary matrix to produce the transmitter beamforming information and then wirelessly sends the transmitter beamforming information to the transmitting wireless device.

Abstract: Permuted accelerated LDPC (Low Density Parity Check) decoder. This decoding approach operates by processing, in parallel, selected rows for multiple individual LDPC matrix rows from various sub-matrix rows (e.g., first group of rows from a first sub-matrix row, second group of rows from a second sub-matrix row, etc.). A memory structure of daisy chains is employed for memory management of APP (a posteriori probability) values and also for check edge messages/intrinsic information (?) values. A first group of daisy chains may be employed for memory management of the APP values, and a second group of daisy chains may be employed for memory management of the check edge messages. These daisy chains operate to effectuate the proper alignment of APP (or gamma(?)) values and check edge message/intrinsic information (?) values for their respective updating in successive decoding iterations.

Abstract: Accumulating LDPC (Low Density Parity Check) decoder. The accumulating decoding architecture described herein is applicable to LDPC codes operating on a parity check matrix, H, consisting of CSI (Cyclic Shifted Identity) sub-matrices (or matrix sub-blocks) or permuted identity sub-matrices (or matrix sub-blocks). In such a structure, the entire LDPC matrix is broken into square sub-matrices such that each sub-matrix consists of either a CSI sub-matrix or a permuted identity sub-matrix, or a null matrix. The iterative decoding process operates by updating of APP (a posteriori probability) or gamma (?) values and check edge message (?) values, and this by updating one or more individual rows within a number of sub-matrix rows (or all sub-matrix or sub-block rows) are processed in parallel. The amount of parallelism is specified by the designer and is typically an integer divisor of the sub-matrix (or sub-block) size.

Abstract: Low complexity communication device employing in-place constructed LDPC (Low Density Parity Check) code. Intelligent design of LDPC codes having similar characteristics there between allows for a very efficient hardware implementation of a communication device that is operative to perform decoding of more than one type of LDPC coded signals. A common basis of decoder hardware (e.g., decoder circuitry) is employed when decoding all of the various types of LDPC coded signals that such a communication device can decode. However, all of the decoder hardware is only employed to decode signals corresponding to the lowest code rate LDPC code supported by the communication device. A first subset of the decoder hardware is employed to decode signals corresponding to the second to lowest code rate LDPC code, a second subset (being less than the first subset) is employed to decode signals corresponding to the third to lowest code rate LDPC code, etc.

Abstract: Quasi-cyclic LDPC (Low Density Parity Check) code construction is presented that ensures no four cycles therein (e.g., in the bipartite graphs corresponding to the LDPC codes). Each LDPC code has a corresponding LDPC matrix that is composed of square sub-matrices, and based on the size of the sub-matrices of a particular LDPC matrix, then sub-matrix-based cyclic shifting is performed as not only a function of sub-matrix size, but also the row and column indices, to generate CSI (Cyclic Shifted Identity) sub-matrices. When the sub-matrix size is prime (e.g., each sub-matrix being size q×q, where q is a prime number), then it is guaranteed that no four cycles will exist in the resulting bipartite graph corresponding to the LDPC code of that LDPC matrix. When q is a non-prime number, an avoidance set can be used and/or one or more sub-matrices can be made to be an all zero-valued sub-matrix.
