  • Patent number: 9024690
    Abstract: An amplification unit is provided. The amplification unit, comprises a first amplifier, a second amplifier, a first sensor, a first predistortion component, and a signal combiner. The first amplifier amplifies a first signal to produce a second signal. The first sensor produces a third signal based on the second signal. The second amplifier turns on and to amplifies a fourth signal to produce a fifth signal when the amplitude of the fourth signal exceeds a threshold amplitude and turns off when the amplitude of the fourth signal is less than the threshold amplitude. The first predistortion component produces the first signal based on a first input signal, based on the third signal, and based on an on-off state of the second amplifier. The signal combiner produces an output of the amplification unit based on the second signal and the fifth signal.

  • Publication number: 20140094163
    Abstract: Data is downloaded to a wireless device before needed by the user. The data may be downloaded before needed, for example while connected to a high-bandwidth network, slowly over a bandwidth constrained network, during a time when the network is not busy, or when the network operator has reduced tariff for data usage. The data may be downloaded contiguously or may updated over a period of time. At a later point in time, the previously downloaded data is used to provide information to the user without requiring contemporaneous information transmission on the wireless network.

  • Patent number: 8629722
    Abstract: An amplifier having a Doherty-type architecture and a method for operation thereof are provided. The amplifier comprises a main amplifier path comprising a main amplifier, an auxiliary amplifier path comprising an auxiliary amplifier, and an signal preparation unit configured to develop a main amplifier input signal for the main amplifier path and an auxiliary amplifier input signal for the auxiliary amplifier path based on an amplifier input that is to be amplified and a transition threshold associated with the amplifier input. By driving the main and auxiliary amplifiers as a function of the transition threshold, the gain of the Doherty-type amplifier may be increased.

  • Patent number: 8519889
    Abstract: A method and apparatus for estimating location of wireless stations in a wireless communication network are provided. An estimation of a bearing angle of a wireless station from a reference point of a multi-beam antenna pattern is made based on a plurality of beaming angles of a multi-beam antenna pattern and a received signal property, at the wireless station, of each of a plurality of wireless signals transmitted on respective beams of the multi-beam antenna pattern for each of the plurality of beaming angles.
