Abstract: A method for scheduling of periodic real time processes in an operating system, comprising the steps of defining a reference point in time for a periodic real time process, and scheduling the periodic real time process from the reference point in time. Preferably a future point in time is defined as the reference point in time at the start up of the operating system. The real time process is preferably a periodic control process during which a relative control point in time, counted from the beginning of the subsequent control cycle, is calculated during each cycle with absolute time correction counted from the reference point in time. The absolute time correction corresponds to the period of the periodic process multiplied with the number of passed control periods until the beginning of the subsequent control cycle, at which the absolute control point in time is calculated through an addition of the relative control point in time with the absolute time correction. In one embodiment the method according to the invention is applied in an active filter for compensation of variations in an apparatus current consumption from a power grid as a result of changes in the apparatus' electrical load.

Abstract: A combination of a phase shifter, a measurement receiver, and an offset estimator enable the d.c. offset in the transmit path of a quadrature transmitter to be distinguished from the d.c. offset in the measurement receiver. The measurement receiver performs a first measurement on the transmit path output with a “normal” phase shift of 0 degrees and 90 degrees for in-phase (I) and quadrature (Q) components, and a second measurement with a “special” phase shift for the I and Q components. In one embodiment, the “special” phase shift for the I and Q components is 180 degrees and 270 degrees, respectively.

Abstract: Predistortion that will compensate for distortion introduced by a power amplifier circuit is determined by applying a time-varying reference signal to the power amplifier circuit, wherein at each moment the time-varying reference signal has a reference amplitude and a reference phase. A corresponding output signal supplied by the power amplifier circuit is measured, wherein at each moment the output signal has a measured amplitude and a measured phase. Amplitude predistortion is determined by comparing the reference amplitude with the measured amplitude, and phase predistortion is determined by comparing the reference phase with the measured phase. A relationship between the phase predistortion and the reference amplitude is determined such that, for any value of the reference amplitude, a corresponding value of the phase predistortion is identified.

Abstract: A wireless communication transmitter is configured to determine transmitter phase shift, and correspondingly includes a derivation circuit, one or more slope polarity tracking circuits, and a phase shift computation circuit. The derivation circuit derives a reference signal from a signal input to the transmitter and a feedback signal from the transmit signal corresponding to that input signal. So derived, differences in the reference and feedback signals reveal the effect the transmitter has on the transmit signal. Accordingly, the transmitter focuses on differences in the polarities of the reference signal's slope and the feedback signal's slope to determine the effect the transmitter has on the phase of the transmit signal. That is, the slope polarity tracking circuits track the slope polarities of the reference and feedback signals, while the phase shift computation circuit computes the transmitter phase shift as a function of differences in those tracked slope polarities.

Abstract: A method and apparatus adaptively compensates for nonlinearities of a power amplifier by measuring a distortion characteristic across the power amplifier during amplification of a distortion detection signal. The distortion detection signal has a well-defined input power versus time relationship, such as ramp-up signal or ramp-down signal. Due to this well-defined relationship, the distortion characteristic can be calculated as a function of the input power level. This calculated function is then utilized to update a predistortion lookup table.
