Appl. No.:

11/617011

Inventors:

Stephen N. Levine - Itasca IL, US
Lawrence M. Ecklund - Wheaton IL, US
Stephen L. Kuffner - Algonquin IL, US

Assignee:

MOTOROLA, INC. - Schaumburg IL

International Classification:

H04Q 7/00
H04Q 7/24

US Classification:

370329, 370338, 370401, 370466

Abstract:

A node of a wireless mesh network assigns a radio frequency (RF) channel for operation by sensing an interference level in a number of RF channels, determining which RF channels are available for use and selecting the available RF channel having the best performance. The node then attempts to communicate with neighboring nodes of the wireless mesh network using the selected RF channel. If communication with a sufficient number of nodes is not achieved, the node selects an available RF channel having the next best performance, and attempts to communicate with neighboring nodes using the selected RF channel. The process is repeated until the node can communicate with a sufficient number of nodes. The selected RF channel is then assigned for node operation.

International Classification:

H04Q 7/00

US Classification:

370329

Abstract:

A method and apparatus for allocation of shared spectrum in a wireless communication system uses a radio frequency (RF) beacon signal that is transmitted between access points of the wireless communication system. The information content of the RF beacon signal includes an identifier of the access point that generated the signal, identifiers of clients of that access point; and identifiers of the communication channels assigned to those clients. The client identifier may include at least part of an Internet Protocol (IP) address of the client. Additionally the beacon signal may contain client attributes to enable negotiation of the sharing of available communication channels between access points and clients.

Appl. No.:

8/258134

Inventors:

Stephen N. Levine - Itasca IL
Michael P. Metroka - Algonquin IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H03M 1300

US Classification:

371 35

Abstract:

The extended error correction process of the present invention error corrects a data message that has been transmitted a plurality of times. The process first receives the data message at least twice, logically combining the first and second messages received to form an error indication word. The error indication word is then used to locate the error locations in each message after which some of the errors are complemented, depending on the total number of errors found. The message is then decoded and used for transmit power changes, channel reassignment, to release a call, etc.

Appl. No.:

8/344251

Inventors:

Cheung Auyeung - Hoffman Estates IL
Stephen N. Levine - Itasca IL
James J. Kosmach - Atlanta GA

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04N 1417
H04N 712

US Classification:

3582612

Abstract:

The present invention provides a method (100) and device (200) for allocating bits to video pictures in a video compression system. A sequence of video frames or pictures is received, and the number of bits used to compress a previously encoded frame and a signal-to-noise ratio for the immediately previously encoded video frame are determined. Rate distortion model parameters are updated. Then, first, second, and third deviations are determined. Finally, the bit allocation for the frame is determined based on the first number of bits used to compress a previously encoded frame, the first deviation, the second deviation, and the third deviation.

International Classification:

H04N 1417

US Classification:

39520077

Abstract:

A method (100, 200), device (300) and microprocessor (400) are provided for selectively compressing video frames of a motion compensated prediction-based video codec based on a predetermined set of compression techniques. An energy estimate of the current displaced frame difference, DFD, is used to compute a ratio between the estimate and a historical mean of energy estimates. The ratio is iteratively compared to a predetermined set of thresholds which are associated with the predetermined set of compression techniques. The comparisons are used to choose a technique based on the thresholds, and a technique is selected to be used for encoding the current DFD.
