    摘要： A full-duplex RF communication system and corresponding methods use digital adaptive filters for interference cancellation. As provided, the techniques allow full-duplex radio frequency communication without frequency-, time-, or code-division multiplexing and without the use of hardware RF cancellers. Such techniques may be useful for wireless communication, such as cellular communication, radio communication, broadcasting, short-range point-to-point communication, wireless sensor networks, and wireless computer networks.

    摘要： Provided are methods and systems of selectively decoding optical data read from an optical storage medium based on a checksum algorithm technique. In one embodiment, optical data is converted into a data stream and buffered, and the checksum algorithm is applied to the data stream. If the calculated checksum matches an encoded checksum of the data stream, the data stream may be output without requiring further decoding. If the calculated checksum does not match the encoded checksum, the buffered data stream may be decoded to produce a corrected data stream, and the checksum algorithm may be applied to the corrected data stream. In some embodiments, the optical data may be re-read if the corrected data stream does not pass the checksum test, and the data stream obtained from the re-reading may be combined with the buffered data stream for further decoding.

    摘要： Techniques are provided for increasing storage capacity in a holographic storage system. While typical holographic storage systems involve binary storage for each data position in a holographic disk, present techniques involve storing data such that more than two data levels may be recorded in each data position. In some embodiments, a recording beam directed to the disk may be adjusted to different power levels depending on the data level to be recorded. Furthermore, the recording time at a data position may be adjusted to increase the energy directed to the data position by increasing the amount of time the recording beam is impinged on the data position. Embodiments are suitable for different types of holographic storage, including dye-based medium.

    摘要： The present techniques provide methods and systems for more reliable reading of optical data disks. In embodiments, a multi-pixel detector that is segmented into multiple areas, or detector segments, may be used to detect a pattern in the light reflected from an optical data disk. The pattern may include light scattered from a single bit that may be under a center detector, as well as light scattered from proximate bits. The detector system may then combine the quantized values from each of the detector segments mathematically to determine the presence or absence of a bit or bits of data. The mathematical combination may also use data that is known about the status of adjacent data bits (such as previously read bits, or bit patterns which are allowed or not allowed by specific data encoding schemes) to improve the accuracy of the bit prediction.

    摘要： A method for processing information is provided. The method includes directing a laser beam to a first track of a first layer of a holographic storage medium. The method also includes recording a base voltage based on a look-up table. The method includes directing the laser beam to a target track in the first layer, based on position information in tracks. Further, the method includes recording an offset voltage for the target track into the look-up table. Still further, the method includes directing the laser beam to a target layer based on position information in vertical wobbles. The method also includes recording an offset voltage for the target layer into the look-up table. Finally, the method includes determining a final voltage based on the look-up table and applying the final voltage to an actuator for moving the laser beam to a final target position in the holographic storage medium for recording and retrieval of information.

    摘要： Provided are methods and systems of managing vertical handoffs in a wireless communication network. Embodiments include analyzing wireless device usage to determine usage patterns, which may include locations and times at which the wireless device is typically accessing the network. The network may recognize points in the usage patterns at which signal quality parameters are typically reduced. Such reductions in signal quality parameters may lead to inefficient vertical handoffs. The network may decrease adverse effects of inefficient vertical handoffs by reducing ping ponging, selecting links between wireless devices and network nodes, or indicating to a user of the wireless device that delays and/or data loss may occur.

    摘要： The present techniques provide systems and methods for decoding a data signal with a control bit to improve bit estimation. The techniques in one embodiment involve using decoding algorithms to estimate the a posteriori state probabilities and the a posteriori transition probabilities of the data encoding, and estimating bit state probabilities. The techniques further involve using a control bit in the bit stream and comparing the estimation of the control bit state in the segment of the bit stream with a test control bit determined based on an average of bit states from the encoded segment of the bit stream. If the estimation of the control bit and the test control bit are not equal, the state of the bit estimate with the lowest confidence probability will be changed.
