20130094345 | DYNAMICALLY SELECTING METHODS TO REDUCE DISTORTION IN MULTI-CARRIER MODULATED SIGNALS RESULTING FROM HIGH PEAK-TO-AVERAGE POWER RATIOS - In one embodiment, an algorithm dynamically selects a method for reducing distortion in a multi-carrier modulated signal, such as an orthogonal frequency division multiplexing (OFDM) signal. The algorithm directs a transmitter to transmit peak-to-average power ratio (PAPR)-reduction signals over reserved tones (i.e., frequencies) if reserved tones are available. If reserved tones are not available, then the algorithm directs the transmitter to transmit PAPR-reduction symbols over free tones if free tones are available. If the free tones for this transmitter are used by adjacent transmitters, then interference-reduction techniques may be used to reduce interference with the adjacent transmitters. If reserved tones and free tones are not available, then the transmitter may use an alternative method to reduce distortion, such as successive clipping and filtering. In another embodiment, the transmitter may transmit PAPR-reduction symbols over both free and reserved tones, if available. | 04-18-2013 |

20090080506 | RECEIVER EMPLOYING NON-PILOT REFERENCE CHANNELS FOR EQUALIZING A RECEIVED SIGNAL - In one embodiment, a receiver has a reference generator and a main equalizer. The reference generator equalizes a received signal using one or more pilot reference signals. Then, the reference generator decodes one or more predetermined data channels of the equalized signal, makes hard decisions on the data of each decoded channel, and regenerates the original coding sequence of each decoded channel. The main equalizer uses each re-encoded channel as an additional reference signal along with one or more pilot signals to equalize a time-delayed version of the received signal. In alternative embodiments, the receiver might also have a step-size generator which selects optimum step sizes from a look-up table based on the number of re-encoded channels and the power of those channels. The step size is then used by the main equalizer along with the re-encoded channels to equalize the time-delayed received signal. | 03-26-2009 |
20090296798 | HSDPA CO-PROCESSOR FOR MOBILE TERMINALS - In one embodiment, an HSDPA co-processor for 3GPP Release 6 Category 8 (7.2 Mb/s) HSDPA that provides all chip-rate, symbol-rate, physical-channel, and transport-channel processing for HSDPA in 90 nm CMOS. The co-processor design is scalable to all HSDPA data rates up to 14 Mb/s. The coprocessor implements an Advanced Receiver based on an NLMS equalizer, supports RX diversity and TX diversity, and provides up to 6.4 dB better performance than a typical single-antenna rake receiver. Thus, 3GPP R6 HSDPA functionality can be added to a legacy R99 modem using an HSDPA co-processor consistent with embodiments of the present invention, at a reasonable incremental cost and power. | 12-03-2009 |
20100177832 | CALCULATING PEAK-TO-AVERAGE POWER RATIO REDUCTION FOR MULTI-CARRIER MODULATED SIGNALS USING A GRADIENT-DESCENT APPROACH - In one embodiment, the present invention is a method for reducing the peak-to-average power ratio (PAPR) of a multi-carrier modulated symbol, such as an orthogonal frequency division multiplexed (OFDM) symbol. The method first transforms a set of data symbols into a multi-carrier modulated symbol. The method then uses the multi-carrier modulated symbol and a gradient-descent algorithm to generate a set of symbols for PAPR-reduction tones. The data symbols and the PAPR-reduction symbols are then transformed to generate an updated multi-carrier modulated symbol. The PAPR-reduction symbols are iteratively updated until a terminating condition occurs (e.g., an acceptable PAPR is achieved for the multi-carrier modulated symbol). In another embodiment, the method uses the multi-carrier modulated symbol generated in the first step and a gradient-descent algorithm to generate an updated multi-carrier modulated symbol directly, where the need for transforming the data symbols and the PAPR-reduction symbols is eliminated for subsequent iterations. | 07-15-2010 |

The request includes (i) an indication that a user invoked the digital mapping service in a vehicle and (ii) an identifier of the user. In response to the request, profile data for the user is automatically retrieved. The profile data includes indications of previous interactions of the user with a digital mapping service. Geographic content then is generated based on the indications of previous interactions in view of relevance of the previous interactions to an automotive context. The generated geographic content is provided to the client device for presentation in the vehicle. | 12-03-2015 |

20100180155 | DYNAMIC TESTING OF NETWORKS - Service providers strive to maintain networks with high levels of availability and performance. To maintain the networks, the service providers measure performance and perform network diagnostics. Measuring performance and performing network diagnostics typically involves manual verification of functionality or performing individual tests between user agents. Service providers who maintain networks and service providers who use networks can dynamically run tests with operations of a signaling protocol (e.g., session initiation protocol) to diagnose network problems and determine appropriate responses. An agent manager can coordinate the dynamic tests across multiple user agents to gather more information to increase problem diagnosis accuracy. | 07-15-2010 |
