US Patent:

6771722, Aug 3, 2004

Filed:

Jul 31, 1998

Appl. No.:

09/126618

Inventors:

John W. Diehl - Elmhurst IL
Henry L. Kazecki - Arlington Heights IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04L 2706

US Classification:

375346, 375232, 375340

Abstract:

In a radiotelephone ( ), a channel estimator ( ) receives a time division multiple access (TDMA) information signal ( ) including a synchronous codeword ( ), formed of a first subset of seven sequential symbols ( ) followed by a second subset of seven sequential symbols ( ), followed by a data sequence ( ) formed of multiple sequential symbols. The channel estimator ( ) uses the first subset ( ) to train, via initializing ( ) and updating ( ), the channel estimator to stabilize the channel estimate. The channel estimator ( ) uses the second subset ( ) to train, via initializing ( ) and updating ( ), the predictor to improve the future accuracy of the channel estimate. The channel estimator ( ) then tracks ( ) the channel estimate over the data sequence ( ) by updating the channel estimator and the predictor over the data sequence ( ), without substantially affecting the stability of the channel estimate or the future accuracy of the channel estimate.

Appl. No.:

09/669015

Inventors:

Wayne H. Bradley - West Chicago IL
John W. Diehl - Elmhurst IL

Assignee:

PrairieComm, Inc. - Rolling Meadows IL

International Classification:

H04B 1702

US Classification:

455138, 4552411, 4552452, 4552511

Abstract:

A receiver generates two metrics, one that is used to control the gain of an amplifier and the other that is used to determine the presence of narrowband interference, such as IMD. The two metrics may represent analog-to-digital converter (A/D) saturation and average signal strength, either of which may be used to control gain or to detect the presence of narrowband interference.

Appl. No.:

8/198662

Henry L. Kazecki - Arlington Heights IL

Assignee:

International Classification:

H04B 710
H04L 102

US Classification:

375347

Abstract:

A diversity receiver (200) recovers clock information from different versions (301, 302) of a transmitted signal (106). The diversity receiver (200) receives the different versions (301, 302), converts the versions (301, 302) into samples (307, 317) via a common sampling clock (309). The receiver (200) then correlates the samples (307, 317) with like synchronization patterns and uses clock information from the received version (307 or 317) which gives the greatest correlation output signal (504, 506) for data detection in one of two detectors (323, 326). The choice of detectors (323, 326) is determined by the diversity receiver (200) by counting the total number of bit-differences output by detectors (323, 326) over a predetermined time period and comparing the total bit-differences with a number represented by a threshold signal (330).

International Classification:

H04L 512
H04L 2302

US Classification:

375261

Abstract:

A rectangular to phase converter (201) includes a first converter circuit (201B) which limits signals to a predetermined level. A phase selector (259) selects a relative phase from the limited signals. According to one aspect of the invention, input rectangular coordinate signals are mapped to the first quadrant in a first quadrant mapping circuit (201A) before the first quadrant signals are limited and the relative phase signal is returned to the original quadrant by an original quadrant mapping circuit (260).

International Classification:

H04K 2700
G06F 752

US Classification:

375259

Abstract:

A complex constellation point multiplier (600) multiplies a complex number by a point in a digital modulation constellation. The desired constellation point is mapped to a digital control word. The complex number is connected to multiplicand input nodes (610, 615) and the digital control word is connected to control input nodes (620, 623, 626). Via logic gates (602, 603, 605, 606, 607, 609), the control word controls switches (651-658) and simple arithmetic blocks, such as accumulators (650, 659), scaler blocks (663, 665), and negation blocks (643, 646), to generate an output complex number that is the product of the input complex number and the constellation point. This complex constellation point multiplier provides a lower size and lower power-consumption alternative to traditional complex number multipliers.

Abstract:

A computer system configured to generate data to provide an interactive graphical interface for display on a remote user device is configured to provide an interactive graphical interface including first and second screen areas, and icons for user manipulation, each icon corresponding to a user goal. Icons corresponding to user goals of a first set are displayed within the first screen area, and icons corresponding to user goals of the second set are displayed in the second screen area. A gap is calculated and displayed based on data associated with icons and stored data. Responsive to receipt of data indicative of drag and drop movement of an icon between the first and second screen areas, the gap is recalculated and a resized gap is displayed.
