20130163694 | ARCHITECTURE OF A LOW BANDWIDTH PREDISTORTION SYSTEM FOR NON-LINEAR RF COMPONENTS - Systems and methods for compensating for non-linearity of a non-linear subsystem using predistortion are disclosed. In one embodiment, a system includes a non-linear subsystem and a predistorter configured to effect predistortion of an input signal of the non-linear subsystem such that the predistortion compensates for a non-linear characteristic of the non-linear subsystem. In addition, the system includes a narrowband filter that filters a feedback signal that is representative of an output signal of the non-linear subsystem to provide a filtered feedback signal, and an adaptor that adaptively configures the predistorter based on the filtered feedback signal and a reference signal that is representative of an input signal of the non-linear subsystem. By utilizing the filtered feedback signal, rather than the feedback signal, a complexity, and therefore, cost of the adaptor is substantially reduced. | 06-27-2013 |
20130165060 | ARCHITECTURE OF NONLINEAR RF FILTER-BASED TRANSMITTER - Systems and methods for compensating for a non-linear characteristic of a non-linear filter in a transmit chain of a transmitter using predistortion are disclosed. In one embodiment, a transmitter includes a power amplifier configured to amplify a radio frequency input signal to provide an amplified radio frequency signal, a non-linear filter configured to filter the amplified radio frequency signal to provide an output signal of the transmitter, and a predistorter configured effect predistortion of the amplified radio frequency signal, where the predistortion compensates for a non-linear characteristic of the non-linear filter. In this manner, the output signal is as if the non-linear filter were a linear, or substantially liner, filter. The predistortion applied by the predistorter may be fixed or adaptive. | 06-27-2013 |

20100110955 | SIGNALLING CHANNEL AND RADIO SYSTEM FOR POWER SAVING IN WIRELESS DEVICES - Wireless devices, transmitters, systems and methods are provided that have a narrow band signalling channel and a wide band channel, for example an OFDM channel. In order to save power, the wireless device is nominally powered down with the exception of a receiver specific to the narrow band signalling channel. Once instructed to do so over the narrow band signalling channel, the wireless device wakes up the rest of its wide band receive circuitry. | 05-06-2010 |
20140347125 | EFFICIENT POWER AMPLIFICATION OVER LARGE OPERATING AVERAGE POWER RANGE - Embodiments of a Doherty power amplifier that maintain efficiency over a large operating average power range are disclosed. In one embodiment, the Doherty power amplifier includes reconfigurable main and auxiliary output matching networks and a fixed combining network. The reconfigurable main and auxiliary output matching networks can be reconfigured such that together the reconfigurable main output matching network, the reconfigurable auxiliary output matching network, and the fixed combining network provide proper load modulation for multiple different back-off power levels. As a result, the Doherty power amplifier maintains high efficiency over an extended back-off power level range. | 11-27-2014 |
20140362951 | CREST FACTOR REDUCTION OF CARRIER AGGREGATED SIGNALS - The present disclosure advantageously provides methods and systems for crest factor reduction of multi-standard carrier aggregated signals. In one embodiment, a method of providing crest factor reduction for a carrier aggregated signal is provided. In one embodiment, the method comprises estimating a peak of a carrier aggregated signal based on a summation of instantaneous amplitudes of baseband representations of a number of component carriers of the carrier aggregated signal. The number of component carriers of the carrier aggregated signal is greater than or equal to 2. The method further comprises clipping the baseband representations of the component carriers if the estimated peak of the carrier aggregated signal is greater than a predefined clipping threshold. | 12-11-2014 |

20080236092 | METHOD OF MANUFACTURING TERRAZZO TILES, TERRAZZO TILES AND FLOORING SYSTEM ASSEMBLED WITH TERRAZZO TILES - A method of manufacturing terrazzo tiles and tiles manufactured in accordance with the method is described. A resin, curing agent, filler, and pigment are poured into a mold. Stone chips are then poured into the mold to settle with the majority at the bottom of the mold. Thereafter, curing occurs to result in rough tiles which are ground and then polished with the upper surface being the resulting tile surface at which the majority of the stones settle. The tiles are assembled onto a floor with grout lines resulting from spacing of the tiles, one from another. Grout is then poured in and skived, and the floor polished to result in a sealed monolithic surface. | 10-02-2008 |
