Abstract: Interference-reducing circuits include a feed-forward circuit for subtracting all or part of a desired transmitter-signal component from a signal coupled from the power amplifier's output path. The error signal from this feed-forward circuit contains a replica of distortion in the power amplifier output. A cancellation loop adjusts the phase and/or amplitude of this error signal and combines this adjusted error signal with an interference-carrying signal, removing some of the undesired distortion. A spread-spectrum pilot signal is used in one or both loops, to provide a reference signal that can be monitored by an adjustment circuit, which measures the magnitude and/or phase of a spread-spectrum signal that is injected into the interference-carrying signal and, based on that measurement, adjusts the amplitude, phase, and/or delay of the cancellation signal that is added to the interference-carrying signal. This yields a reduced-interference signal in which undesired distortion is reduced.

Abstract: Methods and apparatus are provided for efficiently amplifying or converting a signal. An input signal is decomposed into a plurality of two state signals, each two state signal having a respective on level and off level. This may involve sigma-delta modulation and phase splitting. For amplifier applications, each of the two state signals is amplified with a respective switching power amplifier to produce a respective amplified signal.

Abstract: Embodiments of a centralized predistortion system and corresponding adaptive predistortion processes are disclosed. In general, a central node includes one or more centralized predistortion components that enable predistortion for one or more remote transmit chains in order to compensate for non-linearity of power amplifiers in the one or more remote transmit chains. For instance, in one embodiment, the central node is a hub base station and the one or more remote transmit chains are included in one or more transmitters at one or more satellite base stations.

Abstract: A device is provided having a local oscillator (LO) configured to generate a first signal comprising at least one of: timing information; frequency information; phase information; and combinations thereof. The device also has a LO error corrector comprising an input, the input configured to receive a second signal comprising at least one of: timing information; frequency information; phase information and combinations thereof, wherein the second signal is used for disciplining the LO. The LO error corrector is configured to: if the second signal is unavailable to discipline the LO, discipline the LO using a source that is less accurate than the second signal. Upon the second signal becoming at least temporarily available, the LO corrector determines an offset error of the LO relative to the second signal. If the second signal becomes unavailable before the device uses the second signal to discipline the LO on an ongoing basis, the LO corrector corrects the offset error of the LO relative to the second signal based information obtained during the second signal's temporary availability and disciplines the LO using a source that is less accurate than the second signal until the second signal becomes at least temporarily available at a subsequent time.
