Predistortion System And Method Using A Pilot Signal

View page
US Patent:
6496062, Dec 17, 2002
Filed:
Jul 13, 2001
Appl. No.:
09/904611
Inventors:
William Allen Nitz - Rockaway Township, Morris County NJ
Josef Ocenasek - Whippany NJ
Christopher F. Zappala - Annandale NJ
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
H03F 366
US Classification:
330 52, 330136, 330149
Abstract:
A predistortion system uses a pilot signal to determine a predistortion function which is used to produce amplitude and/or phase adjustment(s) of an input signal on a signal path. Rather than simply detecting the input signal envelope before and after distortion generating circuitry, such as an amplifier, a pilot signal is provided on the signal path prior to the distortion generating circuitry. After the distortion generating circuitry, the pilot signal is detected. The predistortion system can determine the predistortion function by using the generated pilot signal and the detected pilot signal, for example, to provide improved characterization of the amplifier amplitude and/or phase response or to directly improve the determination of the predistortion function. In certain embodiments, the predistortion function is implemented using a look-up table to produce the amplitude and/or phase adjustment values, and the pilot signal is produced on the signal path by adding the pilot signal to the amplitude and/or phase adjustment values of the look-up table.

System And Method For Producing An Amplified Signal Using Plurality Of Amplitudes Across Spectrum

View page
US Patent:
6674324, Jan 6, 2004
Filed:
Aug 24, 2000
Appl. No.:
09/645125
Inventors:
Josef Ocenasek - Whippany NJ
Christopher F. Zappala - Annandale NJ
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
H03F 366
US Classification:
330 52, 330149, 330151
Abstract:
An amplifier distortion reduction system detects a plurality of amplitudes corresponding in time within a frequency band of operation. In response to at least one of the plurality of amplitudes, adjustments can be made to components within the frequency band of operation, enabling the amplifier distortion reduction system to adapt to changing operating conditions. In a feed forward embodiment having a carrier cancellation loop and IMD cancellation or distortion cancellation loop, the output of the carrier cancellation loop can be monitored and equalizer adjustments provided to reduce the amplitude of the carrier signal(s) equally over the frequency band of operation. The output of the IMD cancellation loop can be monitored and equalizer adjustments provided to reduce the IMD components equally over the frequency band of operation. Thus, processing circuitry can monitor amplitudes corresponding in time over the frequency band of operation and provide improved performance over the frequency band.

Pre-Distortion Cross-Cancellation For Linearizing Power Amplifiers

View page
US Patent:
7062234, Jun 13, 2006
Filed:
Jul 28, 2003
Appl. No.:
10/628263
Inventors:
Josef Ocenasek - Whippany NJ, US
James C. Giacobazzi - Bloomingdale IL, US
Assignee:
Andrew Corporation - Orland Park IL
International Classification:
H04B 1/04
H04K 1/02
H04L 25/03
US Classification:
4551143, 455 631, 455 6713, 375297, 330149
Abstract:
In an amplifier system having two or more different amplifier sub-systems, the input signal to at least one of the amplifier sub-systems is pre-distorted based on the combined output signal from the two or more amplifier sub-systems. In one embodiment, each other amplifier sub-system pre-distorts its input signal based on only its own output signal. In one operational scenario, during initial operations, each amplifier sub-system separately pre-distorts its input signal based on only its own output signal. After pre-distortion has settled, one of the amplifier sub-systems is switched to pre-distort its input signal based on the combined output signal, while the other amplifier sub-systems continue to pre-distort their input single based on only their own output signals.

Paralleling Digital-Input Amplifiers

View page
US Patent:
7081794, Jul 25, 2006
Filed:
Jun 4, 2004
Appl. No.:
10/861045
Inventors:
Michael E. Burke - Morris Plains NJ, US
Josef Ocenasek - Whippany NJ, US
Jeffrey A. Siegel - Middletown NJ, US
Assignee:
Andrew Corporation - Westchester IL
International Classification:
H03F 3/68
US Classification:
330124R, 330295
Abstract:
Two or more digital-input RF amplifiers are configured in parallel such that a combiner combines their respective outputs to generate a relatively large composite RF output signal. A feedback control architecture minimizes the phase differences between the various amplifier outputs so that the outputs can be efficiently combined. The feedback control can measure the return loss for each amplifier to determine how to adjust each amplifier's phase. In some embodiments, the feedback control can also measure the composite RF output signal for use in phase adjustment. In certain implementations, phase adjustment is implemented by an iterative coarse phase-adjustment mode (e. g. , based on either the return loss or the composite output signal) followed by an iterative fine phase-adjustment mode (e. g. , based on the return loss).

Linearization Of Amplifiers Using Baseband Detection And Non-Baseband Pre-Distortion

View page
US Patent:
7321635, Jan 22, 2008
Filed:
Aug 8, 2003
Appl. No.:
10/637777
Inventors:
Josef Ocenasek - Whippany NJ, US
John S. Rucki - New Providence NJ, US
Assignee:
Andrew Corporation - Westchester IL
International Classification:
H04K 1/02
US Classification:
375297, 375296, 375141, 375130, 330149, 330151, 330136, 4551143, 455 631, 455126
Abstract:
In an amplifier system that linearizes an amplifier by pre-distorting the input signal prior to amplification, a baseband pre-distortion processor processes the input signal in a digital baseband domain to generate one or more pre-distortion parameters based on the power of the digital baseband input signal. The digital baseband signal is up-converted and D/A-converted into a non-baseband (e. g. , IF or RF) signal which is then pre-distorted, e. g. , using a phase/gain adjuster or a vector modulator. By generating the pre-distortion parameters at baseband, while pre-distorting the input signal at non-baseband, the amplifier system avoids the cost and inaccuracies associated with analog signal delay and RF power detection of prior-art “all-RF” pre-distortion implementations, while avoiding the wider-bandwidth filtering of prior-art “all-baseband” pre-distortion implementations.

Amplifer System For Cell Sites And Other Suitable Applications

View page
US Patent:
20100227599, Sep 9, 2010
Filed:
Mar 4, 2009
Appl. No.:
12/397491
Inventors:
Josef Ocenasek - Whippany NJ, US
Jeffrey G. Strahler - Grove City OH, US
Christopher F. Zappala - Annandale NJ, US
Assignee:
ANDREW LLC - Hickory NC
International Classification:
H04M 3/22
H04M 1/00
H03F 1/00
US Classification:
455418, 4555521, 455561, 330 1 R
Abstract:
In one embodiment, an amplifier system has a tap, a delay filter, a linearized amplifier, and a hybrid combiner. The tapped portion of an input signal is amplified by the amplifier, the untapped portion of the input signal is delayed by the delay filter, and the combiner combines the resulting amplified, tapped portion and the delayed, untapped portion to generate an amplified output signal. By re-combining the delayed, untapped portion of the input signal with the amplified, tapped portion, the power of the untapped portion is not lost, and the amplifier does not have to compensate for all of the distortion that would otherwise be associated with the total output power level. Such an amplifier system is applicable, for example, in upgrading an existing GSM cell site to support both GSM communications as well as UMTS communications without degrading GSM operations.

Coupled Loop Controller For A Laser Transmitter

View page
US Patent:
46776320, Jun 30, 1987
Filed:
Oct 28, 1985
Appl. No.:
6/792160
Inventors:
Richard J. Lisco - Whippany NJ
Josef Ocenasek - Parsippany NJ
Assignee:
American Telephone and Telegraph Company, AT&T Bell Laboratories - Murray Hill NJ
International Classification:
H01S 313
US Classification:
372 38
Abstract:
The power output from a laser transmitter is maintained within predetermined levels. These levels are maintained at fixed percentages on either side of the average laser output power which is transmitted, regardless of variations in ambient temperature. This is achieved by coupling the bias current control loop to the modulation current control circuit.
