Appl. No.:

09/578288

Inventors:

Eric M. Dowling - Holmes Beach FL
Umesh Jani - Richardson TX

International Classification:

H04B 169

US Classification:

375130

Abstract:

The present invention provides a processing apparatus and methods for the extraction of user information streams from a composite CDMA waveform. The apparatus and methods increase CDMA system capacity by orthogonalizing an individual users signal from thermal noise components, multi-access interference, and spatially diverse but non-orthogonal coded components. The present invention exploits both the temporal diversity and the spatial diversity present in the received composite CDMA waveform to increase performance. The smart antenna multiuser detector makes use of blind-block-adaptive nonlinear optimization strategies, which are used to separate user signal components from a composite CDMA waveform by jointly processing in both a chip (code) and spatial domain.

Appl. No.:

10/847275

Inventors:

Umesh Jani - Plano TX, US
Austin Hunt - Dallas TX, US

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H04B001/38

US Classification:

375222000

Abstract:

A system for, and method of, reducing noise estimation error during a digital subscriber line (DSL) communication session and a DSL modem incorporating the system or the method. In one embodiment, the system includes: (1) a memory configured to contain data regarding frequency-dependent noise estimation error experienced during a prior DSL communication session and (2) a noise injector coupled to the memory and configured to employ the data to introduce frequency-dependent synthetic noise during a training period of the DSL communication session.

Appl. No.:

12/235619

Inventors:

Michael Frederick Wedemeier - Richardson TX, US
Umesh G. Jani - Plano TX, US
Anne E. French - Allen TX, US

Assignee:

TEXAS INSTRUMENTS INCORPORATED - Dallas TX

International Classification:

H04N 5/50
H04N 7/12

US Classification:

348569, 37524025, 348E05097, 375E07027, 709230

Abstract:

On-screen-display contents are displayed by sending abstracted information of the on-screen-display contents to a data handler of the display device. The data handler translates the abstracted information and passes the translated information to an on-screen-display decoder. The on-screen-display decoder composes the on-screen-display contents using the translated information. The composed on-screen-display contents are displayed on a screen of the display device.
