Scalable Self-Calibrating And Configuring Radio Frequency Head For A Wireless Communication System

View page
US Patent:
8285221, Oct 9, 2012
Filed:
Aug 31, 2009
Appl. No.:
12/550432
Inventors:
Thomas J. Kundmann - Cary IL, US
Gregory T. Nash - Arlington Heights IL, US
Aaron W. Netsell - Woodstock IL, US
Thomas J. Kovarik - Grayslake IL, US
Assignee:
Motorola Mobility LLC - Libertyville IL
International Classification:
H04W 24/00
US Classification:
455 6714, 4555621
Abstract:
A method, a system and a device for implementing a scalable, self-calibrating and configuring, radio frequency head in a wireless base station that performs phase calibration for coherent combining of a pair of transmitter outputs. Configurable Antenna Calibration (CAC) logic initiates phase calibration for coherent combining by selecting a first configuration and triggering the transmission of a reference signal by radio frequency (RF) transmitters using different sub-carriers. The CAC logic generates a vector of phase values by comparing the reference signal with the respective signals received by a calibration receiver. The CAC logic also generates calibration coefficients for coherent combining by normalizing the phase values. In addition, a passive combiner mechanism is employed to implement coherent combining. The CAC logic performs calibration of smart antennas by providing calibration coefficients via a second configuration which utilizes both a calibration transmitter and the calibration receiver.

US Patent:
7362820, Apr 22, 2008
Filed:
May 18, 2005
Appl. No.:
11/131714
Inventors:
Asad U. Aman - Schaumburg IL, US
Thomas J. Kundmann - Cary IL, US
Gregory T. Nash - Arlington Heights IL, US
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H04K 1/02
US Classification:
375297, 375295
Abstract:
A programmable modulator () is programmable to operate in either of a GMSK or 8PSK mode. When operating in a GMSK mode, a signal modulating circuit receives () a bit stream (), maps the bit stream () to a phase value in complex I, Q form and applies a progressive rotation to the phase value according to GMSK specifications. The output () is filtered by a filter circuit (), preferably using a complex Finite Impulse Response (FIR) filter using the standard coefficients for an 8PSK modulation to create () an approximate GMSK output (). A GMSK correction circuit () determines a correction term that is added to the filter circuit output () so as to correct amplitude variations to allow the output to conform to GSM/EDGE standards. The same modulator () may be programmed to operate in an 8PSK mode with linear predistortion.

US Patent:
20100111221, May 6, 2010
Filed:
Oct 30, 2008
Appl. No.:
12/261534
Inventors:
Gregory T. Nash - Arlingotn Heights IL, US
Michael S. Gleason - McHenry IL, US
Thomas J. Kundmann - Cary IL, US
Assignee:
Motorola, Inc. - Schaumburg IL

A transmit data signal () is generated from a baseband data signal (). The transmit data signal () can include one or more non-linear and/or quadrature distortions. An RF receiver circuit () receives the transmit data signal (). A received signal, from the RF receiver circuit (), includes a digital representation of the received transmit data signal (). The received signal is statistically analyzed (). A representation of each distortion of the one or more distortions is identified in the transmit data signal (). At least one information signal () including an information set of distortion adjustments is generated. Distortion of the transmit data signal () is adjusted () based on the information set to reduce the one or more distortions in the transmit data signal ().

Wireless Audio Equipment Using A Quadrature Modulation System

View page
US Patent:
20120163627, Jun 28, 2012
Filed:
Dec 22, 2010
Appl. No.:
12/975730
Inventors:
Michael Joseph Goodson - Bloomingdale IL, US
Thomas J. Kundmann - Cary IL, US
Jeffrey Arthur Meunier - Deerfield IL, US
Assignee:
Shure Incorporated - Niles IL
International Classification:
H04B 15/00
US Classification:
381 941, 375285
Abstract:
A communications system, e.g., a wireless microphone, incorporates a quadrature modulator system to reduce power consumption with respect to traditional approaches and is general in nature to support any two-dimensional digital technique. The quadrature modulator system comprises different subsystems, including a digital-analog transformation circuit, a baseband filter, and a quadrature modulator. The digital-analog transformation circuit converts discrete time samples to a continuous time signal, and further includes an oversampling noise-shaping modulator such as a sigma-delta modulator. The baseband filter then removes out-of-band energy including sampling images and quantization noise. Some of the circuit components may comprise discrete devices that may result in a reduction of power consumption for the quadrature modulator system. Alternatively, some or all of the circuit components may be incorporated in a single electronic device. For example, an in-phase/quadrature-phase (I/Q) converter and oversampling noise-shaping modulator may be implemented within one field-programmable gate array.

Method And Apparatus For Detecting Bad Frames Of Information In A Communication System

View page
US Patent:
60922303, Jul 18, 2000
Filed:
Sep 15, 1993
Appl. No.:
8/121809
Inventors:
Sandra L. Wood - Kenosha WI
Thomas J. Kundmann - Streamwood IL
Lee M. Proctor - Elgin IL
Ken Stewart - Palatine IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H03M 1300
US Classification:
714755
Abstract:
A communication system implements detection of bad frames of information by utilizing multiple bit correction thresholds. Equipment used within the communication system adapts to different signaling environments by dynamically altering the bit correction threshold based on a history of the number of consecutive bad frames of information that have been previously erased and the number of bits corrected by a channel decoder (202). By implementing this dynamic bit correction threshold, sufficient bad frame indication (BFI) detection and receiver sensitivity can be obtained simultaneously, which results in an improved perceived audio quality to the end user.

Increased Frequency Resolution In A Synthesizer

View page
US Patent:
54955050, Feb 27, 1996
Filed:
Dec 20, 1990
Appl. No.:
7/630708
Inventors:
Thomas J. Kundmann - Streamwood IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H04L 2720
H04L 2712
US Classification:
375308
Abstract:
A direct digital frequency synthesizer increases the frequency resolution of the analog output signal by using fractionalization techniques. The best integer value I. sub. FR of a digital signal is determined and the next integer value I. sub. FR +1 of a digital signal is used to determine a weighted fractionalized value of the digital signal. The fractionalized value of the digital signal is used to synthesize the analog output signal having increased frequency resolution. In addition, IFR and IFR+1 are optimally distributed during the weighting process to ensure a minimum cumulative phase error.

Filter Co-Processor

View page
US Patent:
59057572, May 18, 1999
Filed:
Oct 4, 1996
Appl. No.:
8/725871
Inventors:
Thomas Kundmann - Streamwood IL
Mack Mansouri - Wheeling IL
Moshe Tarrab - Holon, IL
Eran Pisek - Holon, IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H03H7/30
US Classification:
375229
Abstract:
A filter co-processor within a Digital Signal Processor (DSP) takes advantage of the orthogonal nature of modulated signals during the equalization process. Since, after reception, only certain real/imaginary values of the received signal are useful for demodulation, the filter co-processor only processes those values to estimate the transmitted signal. By processing only those values useful for demodulation, the filter co-processor is able to process more information in a given amount of time, leading to increased processing when compared to the prior art.
