摘要： Circuitry for providing improved pulse-type enhancement of the voltage supplied to a power amplifier (101) that is fed by a power supply that is connected to the power amplifier (101) at a feeding point through a main supply path that is connected via an inductor (L1). A second feeding point is used for enhancement by a capacitor that is discharged. A transformer L2, L3, M) is formed by mutually coupling an additional inductor (L3), through which an additional supply path is connected. Enhancement power is provided partially through the transformer L2, L3, M) and the remaining part thorough the capacitor (C1). This way, the total level of possible enhancement is increased, while minimizing distortion of the envelope of the amplified RF signal.

摘要： A method and apparatus for estimating channel impulse response and data in a signal transmitted over a channel in a communication system. The channel impulse response is estimated uses correlative channel sounding, and then, using the estimated channel impulse response, the data in the signal is estimated. The output is then fed back to the channel impulse response estimator and the channel impulse estimation is repeated. The data estimation and channel impulse response estimation may be iterated a number of times.

摘要： Method and apparatus for improving the efficiency and the dynamic range of a power amplifier operated with signals having a large peak-to-average ratio. A reference level is determined, above which at least a portion of the magnitude of an input signal being a modulated signal that is input to the power amplifier, or a baseband waveform that is used to generate the modulated signal, is defined as an excess input signal. The magnitude of the input signal is continuously sampled, for detecting an excess input signal. A lower level of operating voltage is supplied to the power amplifier, if no excess input signal is detected. The lower level of operating voltage is sufficient to effectively amplify input signals having a magnitude below the reference level. A higher level of operating voltage is supplied to the power amplifier, whenever an excess input signal is detected. The higher level of operating voltage is sufficient to effectively amplify input signals having a magnitude above the reference level.

摘要： Method and circuit for stabilizing the output power of a power amplifier, operated with signals having a large peak-to-average ratio and fed by a DC power supply with fluctuating output voltage. An allowable fluctuating range for the voltage output from the DC power supply and a constant voltage level are determined. A controllable voltage enhancement circuitry that can output an enhancement voltage is provided. The input of the voltage enhancement circuitry and a first DC supply path are connected to the output of the DC power supply. The output of the voltage enhancement circuitry is connected to a second DC supply path. While the instantaneous value of the fluctuating output voltage is lower than the constant voltage level, the voltage enhancement circuitry generates an enhancement voltage that causes the sum of the voltages supplied through the first and the second supply paths, to be identical to the constant voltage level.

摘要： The invention provides methods and apparatus for adaptive adjustment of the phase and amplitude controllers that are needed in Feed Forward Linearized Amplifiers (FFLA) to balance, first, the desired signal component and then the distortion component for the eventual full suppression of the latter. The particular advantage of the methods of the invention is that the adaptive adjustment is achieved without the need for additional RF reference or pilot signals and without RF correlators as proposed in prior art; rather, it is based solely on envelope-detected samples of the signal at two test points and on perturbations of the quiescent operating points of the amplifiers and/or other components, such as vector modulators, by appropriately selected voltage patterns. All these operations are at base band frequencies which makes the apparatus for the adaptive control implementable in simple digital circuitry.

摘要： A method and apparatus for producing a frequency-controlled loop in a phase-diversity receiver for demodulating received ON-OFF-keyed (OOK) and phase shift keying (PSK) signals, by feeding a reference frequency signal and the received signals to a quadrature mixer (QM) which produces two output signals in phase quadrature at nominally zero intermediate frequency. Quadrature continuous wave signals void of the modulation are produced from the phase quadrature output signals. A voltage proportional to the frequency of the quadrature continuous wave signals is generated and is utilized for controlling the frequency of the generated reference frequency signal.
