Appl. No.:

09/712888

James Nolan - Huntington NY, US
Leonid Kazakevich - Plainview NY, US
Fryderyk Tyra - Huntington Station NY, US
Robert Regis - Huntington NY, US
Fred Schreider - Commack NY, US

Assignee:

InterDigital Technology Corporation - Wilmington DE

International Classification:

G06F 9/455

US Classification:

703 28, 703 2, 716 5, 375224, 370248, 370249, 370252, 379 2201, 379 2208, 379 2704, 379 2902

Abstract:

A communication system emulator digitally emulates a plurality of signal impairments created by the transmitter and receiver components and communication medium in a typical communication system, for use in evaluating and refining modem design. A variety of linear and non-linear distortion characteristics are impressed on baseband signals between modulators and demodulators to evaluate and refine modem performance without requiring transmission frequency components or communication channel. The emulator comprises transmit modules, receive modules and communication media modules, and can accept or output analog or digital signals. Each module is configurable to allow modeling of simplex or duplex communication, or a common base station with multiple users transmitting or receiving, all configurations with or without communication media impairment emulation. Each module can be configured to add a plurality of linear and non-linear impairments to a baseband signal.

Assignee:

InterDigital Technology Corporation - Wilmington DE

International Classification:

H04B 17/00

US Classification:

375224, 375222

Abstract:

A method for emulating signal impairments to enable dynamic evaluation of transmit and receive modem performance through the use of computer-generated models enabling both an evaluation of system performance as well as a comparison of results obtained from system designs respectively exposed to both impaired and unimpaired conditions to enable direct comparison as well as comparison with standardized measurement values to facilitate system design activities prior to any hardware implementation.

International Classification:

H04W 24/00

US Classification:

4554561

Abstract:

A method and apparatus determines a physical location of a wireless infrastructure device. At least one coarse location data from an associated terminal device is determined. Additional coarse location data are stored and accumulated. The device location is considered accurate by determining that enough received coarse location data has been received.
