摘要： The present techniques provide systems and methods for modulation coding of data on optical disks, such as holographic data disks, and techniques for reading that data back from the disks. The techniques involve parsing a bit stream into a sequence of individual bit-patterns, and then using the individual bit patterns to select a symbol, or matrix, from a lookup table of previously selected matrices. The symbols are selected according to predetermined criteria that may help make the disk more resistant to interferences and errors, such as surface scratches, and the like. For example, criteria that may be used to select the symbols are the number of reflective and non-reflective regions within each matrix, and the number of sequential reflective regions, among others. The symbols may be written to the disk in a two-dimensional fashion, e.g., across adjacent tracks, or in a three-dimensional fashion, e.g., across adjacent data layers.

摘要： The present techniques provide methods and systems for reading and processing a data signal read from an optical data disc. In embodiments, an optical reader system may read data bits from a data ring in the disc. The data rings may be concentric, and a beginning of a sequence of data on the data ring may be in substantially the same position as an ending of the sequence. The reader may identify a data ring and begin the read process on the targeted data ring, and may end the read process when the reader reaches the starting point. The data sequence read from the data ring may be decoded to form a bit stream, which may be provided to various output devices. A circular trellis formed from the bit stream may enable the reading of a targeted data sequence without additional tail bits to improve data transmission efficiency.

摘要： Systems and/or methods for relaying messages between nodes in a network (e.g. a wireless network) are provided. In accordance with certain exemplary embodiments, substantially simultaneous communications between nodes may be accomplished. At least one secondary turbo-coded message may be piggybacked onto a turbo-coded primary message. Messages in the network may be queued and sent from a transmitter to at least one receiver based at least in part on the signal-to-noise ratio(s) of the receiver nodes with respect to the transmitter. Thus, it may be possible to realize a network that reduces collision problems, reduces delays in communications, and/or increases throughput.

摘要： A wide-band overlay sequence generator adds an overlay signal to a television signal which is transmitted through a channel. At a receiver, a replica of the transmitted overlay sequence is generated and synchronized to the overlay signal in the received signal. An adaptive equalizer filter effectively adjusts the received television signal so that the channel perturbations are removed from the signal.

摘要： A turbo decoder control comprises an address generator for addressing systematic data, parity data, and systematic likelihood ratios according to a pre-determined memory mapping. The systematic data samples are accessed in the order required by the MAP decoding algorithm such that interleaving and de-interleaving functions in the MAP decoding algorithm are performed in real-time, i.e., without delay. Such memory-mapping in combination with data handling functions (e.g., multiplexing and combinatorial logic) minimizes memory requirements for the turbo decoder and allows for use of programmable interleavers, variable block lengths, and multiple code rates.

摘要： A high-speed turbo decoder utilizes a MAP decoding algorithm and includes a streamlined construction of functional units, or blocks, amenable to ASIC implementation. A gamma block provides symbol-by-symbol a posteriori state transition probability estimates. Two gamma probability function values are provided via selection switches to the alpha and beta blocks for calculating the alpha and beta probability function values, i.e., performing the alpha and beta recursions, respectively, in parallel, thus significantly increasing decoding speed. A scaling circuit monitors the values of the alpha and beta probability functions and prescribes a scale factor such that all such values at a trellis level remain within the precision limits of the system. A sigma block determines the a posteriori state transition probabilities (sigma values) and uses the sigma values to provide soft-decision outputs of the turbo decoder.
