Method And Apparatus For Burst Detecting
View pageUS Patent:
56217668, Apr 15, 1997
Filed:
Oct 31, 1994
Appl. No.:
8/332159
Inventors:
Bradley B. Bakke - Elgin IL
John W. Arens - Grayslake IL
John W. Arens - Grayslake IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H03D 100
US Classification:
375340
Abstract:
A burst detector (140) detects the occurrence of a burst in a signal receiver. A filter (220) having an impulse response characteristic of an expected burst filters a received signal. A subtractor (230) subtracts a filtered version of the received signal from a delayed and filtered version of the received signal to provide a detection signal. A burst edge detector (250) detects a leading edge of the burst based on the detection signal.
Method And Apparatus For System Acquisition For A Subscriber Unit
View pageUS Patent:
61636797, Dec 19, 2000
Filed:
Sep 8, 1998
Appl. No.:
9/149417
Inventors:
Bradley B Bakke - Lake in the Hills IL
Daniel T. Buhmann - Hainesville IL
R. Travis Jones - Lake Zurich IL
Daniel T. Buhmann - Hainesville IL
R. Travis Jones - Lake Zurich IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H04B 7185
US Classification:
455 121
Abstract:
A method for system acquisition for a subscriber unit (112) in a satellite communication system (100) maximizes life of a battery (320) of a battery-powered subscriber unit. A receiver (304) of the subscriber unit is energized only when ring bursts are expected from satellites in the system, serving to minimize consumption of battery power. During just two scans, the subscriber unit acquires enough information to enable it to identify the best beam for monitoring for a ring alert and to predict the nearby beams most likely to carry a ring alert targeted for the subscriber unit. From the received information, the subscriber unit can also perform necessary processes such as passive geolocation. The subscriber unit then enters a low-power standby mode, energizing the receiver only long enough to detect the best beam to scan for a ring alert targeted for the subscriber unit.
Method And Apparatus For Symbol Clock Recovery From Signal Having Wide Frequency Possibilities
View pageUS Patent:
54992737, Mar 12, 1996
Filed:
May 11, 1995
Appl. No.:
8/438721
Inventors:
A. Corbett S. Kull - Palatine IL
Bradley B. Bakke - Elgin IL
John W. Arens - Grayslake IL
Bradley B. Bakke - Elgin IL
John W. Arens - Grayslake IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H04L 700
US Classification:
375355
Abstract:
The present invention provides an apparatus for symbol clock recovery from a received signal having wide range of frequency errors or offsets. Magnitudes of received inphase and quadrature sampled signals are determined (210). These magnitudes are summed and distributed (227) into accumulator registers (231, 232, 233, 235, 237, 239) for accumulating sums of the first and second signals for each sample time and substantially over a length of an expected burst. A maximum-minimum determination circuit (240) chooses the sample time having a largest or smallest sum to provide a recovered clock signal (270). The carrier could then be recovered (260), and a downsampler (250) downsamples the received inphase and quadrature signals based on the recovered clock signal.
Communication Device With Variable Frame Processing Time
View pageUS Patent:
57269831, Mar 10, 1998
Filed:
Aug 9, 1996
Appl. No.:
8/694739
Inventors:
Bradley B. Bakke - Lake in the Hills IL
Victoria Francesca Atienza Buenviaje - Deerfield IL
Victoria Francesca Atienza Buenviaje - Deerfield IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H04B 7212
H04J 322
H04J 322
US Classification:
370337
Abstract:
A TDMA signal of frames of a nominal duration and having time slots is demodulated (120, 150, 160). A time slot assignment circuit (170) assigns and re-assigns time slots in a present and next frame based on TDMA control information. A real-time timing control circuit (180) determines a recovered-data duration for production of recovered data by a data decoder (190). The data decoder (190) produces the recovered-data during the receive-data duration by time compression or expansion during the next frame when a different time slot is re-assigned by the time slot re-assignment circuit (170).
