International Classification:

G06T 1120

US Classification:

345440, 345963

Dec 8, 2000

Appl. No.:

09/733478

Inventors:

Michael R Andrews - Berkeley Heights NJ
Michael James Gans - Holmdel NJ
Partha Pratim Mitra - Summit NJ

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

G01S 302

US Classification:

343726, 343850

Abstract:

A method of wireless communication is disclosed, in which polarization diversity can be utilized to improve fading performance or to increase the capacity of the communication channel in a scattering environment. Complementary signal information is impressed upon, or derived from, corresponding electric and magnetic polarized field components of a transmitted or intercepted electromagnetic wave. Four, five, or even six independent signal channels can thereby be utilized for communication using a localized antenna arrangement.

Nov 27, 2002

Appl. No.:

10/306811

Inventors:

Michael R. Andrews - Berkeley Heights NJ
Partha Pratim Mitra - Summit NJ
Alexander Polyakov - Brooklyn NY

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H01Q 2100

US Classification:

343725, 343726, 343853

Abstract:

A compact antenna and a communication unit having the same comprises one or more input feeds and one or more sets of elements. Each set of elements is coupled to one or more of the input feeds, and each set of elements has a property that input signals applied to input feeds coupled to the set of elements causes a directed beam to be emitted. At least one given element of the set or sets of elements has a largest dimension, and a smallest wavelength to be emitted from the antenna is larger than the largest dimension for the given element. The antenna is adapted to simultaneously transmit the input signals, and generally more than two input signals. When a concentration region for a directed beam is large enough, more than one degree of freedom can be contained in the concentration region. Techniques are presented for designing the compact antenna.

International Classification:

G01S003/02
G01S001/08
G01S001/24

US Classification:

342463, 342386, 342387, 342464

Abstract:

Systems and techniques for location determination. A plurality of tags emitting radio frequency signals are dispersed throughout a region, such as a building, within which a user's location is to be determined. The radio frequency signals emitted by the tags include information that can be used to identify the location in which the tags axe placed, or simply to distinguish the tags from one another. A portable device receives signals from the tags and provides the signal information to a location server that computes the location of the portable device by comparing the signal information received from the portable device to a map of location venus stored signal information, and identifies the location of the portable device as the location for which the stored signal information best matches the signal information received from the portable device.

Appl. No.:

10/195014

Inventors:

Michael R. Andrews - Berkeley Heights NJ, US

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H04B 7/02
H04L 1/02

US Classification:

375267, 375260, 455132, 455504

Abstract:

For use in a wireless communication network that includes a transmitter having a multi-element transmit antenna array, an information hiding system and a method of hiding information. In one embodiment, the information hiding system includes an information spreading subsystem that is configured to scramble the information across the multi-element transmit antenna array. The information hiding system further includes a coherence modification subsystem that is configured to reduce channel coherence randomly during transmission of the scrambled information via the multi-element transmit antenna array. By hiding the information, the information hiding system advantageously reduces an unauthorized eavesdropper's ability to determine the contents of the transmitted information.

Appl. No.:

10/194610

Assignee:

Alcatel Lucent - Paris

International Classification:

H04L 27/06

US Classification:

375340, 375230, 455501, 455 6711, 455296, 370252

Abstract:

This inventions provides techniques for estimating both temporal and spectral channel fluctuations with the duration of a data symbol. Certain pulse shaping functions are Discrete Prolate Spheroidal Sequences (DPSSs) and are used primarily because of their relatively limited Inter-Symbol Interference (ISI) properties. During reception, these properties allow one or more parameters of a joint time-frequency channel model to be more easily determined. Once the one or more parameters are determined, they can be applied to received symbols to correct the temporal fluctuations, spectral fluctuations, or both of the channel over which a communication took place. The techniques may be adapted for the Multiple-In, Multiple-Out communication situation.
