Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H03K 9/00
H03D 1/04

US Classification:

375316, 375346, 375147

Abstract:

The disclosed embodiments relate to a communication system and method. The system may comprise a pre-whitening device that applies pre-whitening data to a received signal from an antenna array to produce a pre-whitened signal, at least one detector that is adapted to recognize a pattern corresponding to a request for access in the pre-whitened signal and compute correlation data corresponding to the pattern, and a threshold detector that determines whether the correlation data exceeds a threshold and indicates that an acknowledgement signal should be transmitted if the threshold is exceeded. The method may comprise the acts of creating a pre-whitened signal by applying pre-whitening data to a received signal, detecting a pattern that corresponds to a request for access in the pre-whitened signal, computing correlation data corresponding to the pattern, determining whether the correlation data exceeds a threshold, and indicating that an acknowledgement signal should be transmitted if the threshold is exceeded.

International Classification:

H04Q 7/00

US Classification:

370334, 370337, 370350, 4554522, 455439

Abstract:

A wireless communication system () includes using multiple antennas () for simultaneous transmissions to multiple mobile stations (). A distributed multiple antenna scheduling (DMAS) technique includes selecting a plurality of mobile stations for at least receiving simultaneous transmissions on at least one selected subcarrier from within a carrier bandwidth having orthogonal frequency division multiplexing (OFDM). In a disclosed example, a plurality of mobile stations are selected for each subcarrier within the carrier bandwidth. A disclosed example includes grouping subcarriers together into subsets to reduce computation complexity for determining which mobile stations to select for the simultaneous transmission.

International Classification:

H04M 15/00

US Classification:

3791142, 37911415

Abstract:

A point-of-sale electronic distribution system for distributing an access code (e. g. , a personal identification number (PIN)) is provided. The system allows retailers/distributors to purchase access codes for use with pre-paid products using conventional telephones and without requiring the use of a dedicated terminal or personal computer at the point-of-sale. A telephone call relating to a request for an access code is received at a central server. An access code is obtained from a database of access codes and transmitted to the caller by telephone, facsimile, or e-mail. Reports relating to a pre-paid calling card account can be requested during the telephone call.

International Classification:

G01R 31/02
G01R 31/00

US Classification:

32476201, 3247503

Abstract:

An integrated circuit includes a process sensor, a temperature sensor, and a voltage sensor. The process sensor is configured to sense a process parameter indicative of a semiconductor process by which the integrated circuit is formed and, based upon the sensed process parameter, to provide a characterization of the semiconductor process to the output of the process sensor. The temperature sensor is configured to provide an indication of a temperature of the integrated circuit to an output of the temperature sensor and the voltage sensor is configured to provide an indication of a power supply voltage level of the integrated circuit to an output of the voltage sensor. The output of the process sensor is coupled to at least one of the temperature sensor and the voltage sensor to compensate at least one of the indication of the temperature and the indication of the power supply voltage level.
