Filed:

Nov 15, 2001

Appl. No.:

09/999261

Inventors:

Shimon B. Scherzer - Sunnyvale CA, US
Benjamin Friedlander - Palo Alto CA, US
Deepa Ramakrishna - Santa Clara CA, US

Assignee:

Kathrein-Werke KG - Rosenheim

International Classification:

H04M 1/00

US Classification:

4555621, 455446, 342368

Abstract:

Disclosed are systems and methods which provide communication network antenna pattern configuration for optimized network operation. Preferably, a statistical smart antenna configuration is provided in which antenna patterns associated with various base stations of the communication network are configured to capitalize on the complex morphology and topology of the service area in providing optimized communications. Antenna patterns are preferably configured using merit based determinations, based upon link propagation conditions such as associated with the complex morphologies and topologies of the service area, to aggressively serve areas which are best served thereby while not serving areas which are best served by other network systems.

Abstract:

Known antenna array manifold information is exploited to provide for fast and accurate channel estimation and demodulation on both the forward and reverse links, thereby increasing capacity in PCS and cellular CDMA networks that use adaptive antenna arrays. On the reverse link, an âextendedâ array manifold is used to assist the demodulator in maintaining a dynamic estimate of the spatial signature to use for beamforming and coherent demodulation. On the forward link, channel estimation is performed in the handset to provide a robust solution for beamforming.
