Filed:

Jan 21, 2000

Appl. No.:

09/489477

Inventors:

Nelson Ray Sollenberger - Farmingdale NJ
Jack Harriman Winters - Middletown NJ

Assignee:

ATT Wireless Services, Inc. - Redmond WA

International Classification:

G01S 124

US Classification:

342387, 342457

Abstract:

A method of locating a mobile telephone includes steps of receiving, transmitting, increasing and determining. In the receiving step, a first base station receives a call from a mobile telephone, the call including a dialed number and a TDMA signal. In the transmitting step, the base station transmits a control message to the mobile telephone when the dialed number meets a predetermined criterion, such as being 911. The control message instructs the mobile telephone to transmit the TDMA signal at a maximum power. In the increasing step, the mobile telephone increases the TDMA signal to maximum power in response to the control message. Then in the determining step, location information for the mobile telephone is determined based on at least one characteristic of the TDMA signal received at at least one of the first base station and other base stations. In an alternate embodiment, the method is practiced in a mobile telephone and the power level is automatically increased in response to the dialed number meeting a predetermined criterion.

International Classification:

H04B 702

US Classification:

455504, 4552781, 455506, 342383, 375267, 375349

Abstract:

The present invention discloses a method for predicting fast fading using sinusoidal modeling techniques. The method first applies a finite impulse response low pass filter to the incoming signal thus increasing the fading power to noise ratio. Applying a root-MUSIC frequency estimation model, a sinusoidal model for the fading process is obtained. This model can be used to enhance the performance of spatial diversity schemes or temporal processing schemes to reduce the effect of the fading.

Assignee:

ATT Corp. - New York NY

International Classification:

H04B 710

US Classification:

375347, 455135

Abstract:

The present invention provides techniques to determine an antenna selection and associated weights for a transmission system having multiple antennas. A receiver first samples signals received on each antenna and the channel characteristics for each received signal is calculated. The signal-to-interference-plus-noise (SINR) ratio for various combinations of antennas is estimated using the channel characteristics and a subset of antennas and accompanying weights are determined that can provide an advantageous SINR.

International Classification:

H04B015/00

US Classification:

455506, 455 25, 4552771, 4555621

Abstract:

A wireless communication system and method includes antenna arrays at both the transmitter and receiver having a plurality of elements for very high data rate communication. Phased array antennas or directive fixed beam antennas are used with a beamwidth in azimuth and elevation less than 30 to increase the power margin and to decrease the delay spread of signals at the receiver to permit wireless data communications at high data rates in closed environments, for example, bursty transmissions and isochronous communications. The wireless communication system is capable of data transmission rates which exceed 1 Gbps with propagation losses of up to at least 60 dB relative to one meter.

International Classification:

H04B007/10

US Classification:

375347, 375371

Abstract:

The present invention provides methods and systems that generate symbol delay times. By receiving a communication signal using a plurality of antennas, a set of respective communication channels can be characterized. The characterized channels can be then used to determine sets of forward-time delays and time-reverse delays using a minimum-mean-square-error technique. By selecting the set of delays that can provide a lower mean-square-error in an equalizer, symbol estimation can be improved as compared to a system that only estimates delays in a single temporal direction.
