摘要： A linear envelope tracking radio frequency (RF) power amplifier having an adaptive analog signal processing circuit. The amplifier outputs a voltage which is sampled by the adaptive analog signal processing circuit. The adaptive analog signal processing circuit generates an error signal which varies the linearity of the power amplifier. In one embodiment, the error signal controls a modulator which in turn controls the supply voltage to the power amplifier. In another embodiment, the control signal varies a controller which in turn varies a load placed on the power amplifier. The load in turn varies in linearity of the amplifier.

摘要： A power linearizer of a CDMA system preferably includes a linearization input unit for compensating a level of an input signal to remove a non-linearity of a power amplifier; an amplification controller for controlling an amplification of the power amplifier; and the power amplifier operated under the control of the amplification controller, for amplifying the power of the level-compensated input signal. By adjusting the voltage inputted to the input terminal of the voltage controlled power amplifier (VCA), the non-linearity of the VCA can be accurately compensated and the power compensation can be easily performed. In addition, the capacity of the CDMA system can be increased.

摘要： Providing a distortion compensating device which can significantly remove residual distortion. The value of the matching circuit 11 is set up so that the distortion generated at the gain controlling unit 9 offsets the distortion remaining in the power amplifier 12. That is, the value of the matching circuit 11 is set up so that the phase of the residual distortion included in the output of the matching circuit 11 is rendered opposite to the phase of the residual distortion included in the output of the power amplifier 12. Thus, the residual distortion included in the output of the power amplifier 12 is offset by the residual distortion included in the output of the gain controlling unit 9, thereby the residual distortion can be removed.

摘要： The invention relates to a method of outsourcing intermediate results of an internal data processing to an external memory, to a corresponding device for processing data having an interface for outsourcing intermediate results, to a disk drive having a corresponding device for processing data, and a cellular phone having a device for processing data. This method can be applied when confidential data is processed but intermediate results thereof need to be stored externally to the processing. First intermediate result data units (I1) are combined with first verification data units (V1) in order to provide a data signal (S1), which is encrypted (E1) and stored in an external memory (5). When the intermediate result data units (I1) stored in the external memory (5) are needed during a subsequent internal data processing a data signal (E2) is read from the external memory (5). After the decryption of the read data signal second verification data units (V2) and second intermediate result data units (I2) are obtained. Said second read verification data units (V2) are verified with said first verification data units (V1) in order to detect any manipulation of the intermediate result data during the time that they were stored in the external memory (5).

摘要： A method and apparatus determines the presence of and source of instabilities, such as limit cycles, within a process control loop while the process control loop operates on-line within a process environment. The method and apparatus measures one or more signals within a process control loop when the process control loop is connected on-line within a process control environment, stores the measured signal as signal data and then performs one or more statistical analyses on the stored signal data to determine whether instabilities exist and, if so, whether the source of an instability is within a servo loop or outside of a servo loop and is due to friction, external forces or mechanical anomalies.

摘要： This invention relates to a phase and amplitude detector (160) required to identify small signal errors in a signal envelope having a large dynamic range, especially in the context of linearization of a power amplifier (122) arrangement employing a pre-distortion technique. A vector generator (300, 352, 372) responsive to a reference signal R (110) produces a frame of reference vectors R1-Rn (274-280) generated by a combination of the reference signal R (110) with first A (270) and second P (272) offset vectors that provide an amplitude and phase displacement of the reference signal R (110). A signal combiner (290-296, 360-366, 390-396) is arranged to generate difference vectors E1-En by combining the frame of reference vectors R1-Rn (274-280) and the feedback signal F (124, 150), with the difference vectors E1-En expressing the phase (p, 254) and the gain (a, 252) error terms relative to the reference signal R (110) and the first A (270) and second P (272) offset vectors. An error signal detector, (330-336) responsive to the difference vectors E1-En and arranged to provide a measure of the phase (p, 254) and the gain (a, 252) error terms, provides signal amplitudes that can be combined to generate error signals (182 (Y), 184 X)). The error signals take the general form:XnullP1nullP2nullP3nullP4nullnull8PpR;YnullP1nullP2nullP3nullP4nullnull8AaR
