| 20110216626 | DIGITAL HYDROPHONE - A digital underwater acoustic sensor system is disclosed. The system can include an acoustic sensor configured to detect an underwater acoustic signal and form an analog signal proportional to the underwater acoustic signal. The acoustic sensor can include an interior cavity. A digital communication module can be positioned within the interior cavity. The digital communication module comprises an amplifier configured to amplify the analog signal. An analog to digital converter is configured to convert the analog signal to a digital signal. A digital signal transmission module is configured to communicate the digital signal to a receiver. | 09-08-2011 |

| 20100266007 | DUAL PDFE SYSTEM WITH FORWARD-BACKWARD VITERBI - The present invention provides a novel technique for improving the performance of equalizers by reducing the effects of error propagation in equalizers that use a Viterbi Decoder. Methods and systems are described that can improve the performance of equalizers by reducing the effects of error propagation in equalizers that use a Viterbi Decoder. Systems and methods of symbol correction in prediction decision feedback equalization (“pDFE”) architectures are described. Systems are described that include one or more enhanced Viterbi decoders together with novel methods of symbol correction to obtain better system performance. Systems and methods are described that utilize dual pDFEs and can use a blending algorithm to reduce errors in symbol decoding. Dual pDFEs are described that include forward and backward Viterbi decoders wherein the backward Viterbi decoded may operate on time reversed data blocks and with some degree of latency. Forward and backward Viterbi decoders can generate different decoded symbols from the same equalized data. A blending algorithm is described for weighting results based on reliability of the respective decoded symbols. A forward-backward blender can additionally increase performance of the second pDFE by blending long delayed trellis symbols from the first Viterbi decoder with symbols output by the second Viterbi decoder. | 10-21-2010 |

| 20090163167 | AUTOMATIC GAIN CONTROL FOR BEAMFORMED SIGNALS - A method of selecting an RF gain of an automatic gain control amplifier includes the steps of measuring a strength of a received signal, the signal reliable and consistent power characteristics, and then measuring an interference level of the received signal, and determining either a target output power level or a target output interference power level based on a ratio of the measured signal strength to the measured interference level. The method also includes determining a gain that, when applied to an incoming signal, will produce a corresponding one of the determined target output power level and the determined target output interference power level. | 06-25-2009 |

| 20100284482 | METHOD AND APPARATUS FOR RADIO RESOURCE ALLOCATION IN AN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING COMMUNICATION SYSTEM - In an OFDM communication system, wherein a frequency bandwidth is divided into multiple Physical Resource Units (PRUs), a Frequency Partitioning Configuration Module (FPCM) is provided that configures a physical layer for use in multiple coverage areas. The FPCM divides the PRUs into a first group, for frequency selective allocations, and a second group, for frequency diverse allocations. The FPCM subdivides each of the two groups into multiple sets of PRUs, maps the sets of PRUs from the first group to consecutive PRUs allocated for contiguous segment allocation (CS-PRUs), and maps the sets of PRUs from the second group to consecutive PRUs allocated for distributed segment allocation (DS-PRUs). The FPCM permutes the DS-PRUs and allocates the CS-PRUs and the permuted DS-PRUs to at least one frequency partition. | 11-11-2010 |

| 20100260234 | CLOSED-LOOP TRANSMISSION FEEDBACK IN WIRELESS COMMUNICATION SYSTEMS - Channel information feedback takes place by calculating channel information to feed back to the base station. The channel quality information is spread by a remote unit with spreading codes from mutually unbiased bases and transmitted to the base station. The advantages of spreading the feedback channel are that multiple mobiles can send their feedback on the same time-frequency resources making the feedback very efficient and also improving feedback performance through orthogonal spreading which gives a spreading gain above noise and interference. Using the spreading codes from mutually unbiased bases can reduce interference across sectors. | 10-14-2010 |
