Synchronization Strategy And Architecture For Spread-Spectrum Receivers

View page
US Patent:
7227886, Jun 5, 2007
Filed:
Jul 29, 2002
Appl. No.:
10/207614
Inventors:
Adam Robert Margetts - Plainsboro NJ, US
Assignee:
Thomson Licensing - Boulogne-Billancourt
International Classification:
H04B 1/00
US Classification:
375149, 375130, 375354
Abstract:
An apparatus for synchronizing the reception of a spread-spectrum signal includes a synchronization apparatus having a code-matched filter, a running average unit coupled to the filter, a peak detector coupled to the running average unit, and a synchronizer coupled to the peak detector for providing an index of a peak. A corresponding method includes receiving a spread-spectrum signal having a period comprising a plurality of indexable samples, maintaining a mean array comprising a running mean value for each indexable sample over a variable number of periods, detecting a peak value of the array, calculating an average value of the array, computing a peak-to-average ratio in accordance with the detected peak value and the calculated average value, comparing the peak-to-average ratio against a time-varying threshold, and synchronizing the received signal when the peak-to-average ratio exceeds the current value of the threshold.

Hybrid Rake/Equalizer Receiver For Spread Spectrum Systems

View page
US Patent:
7693210, Apr 6, 2010
Filed:
Mar 9, 2004
Appl. No.:
10/590577
Inventors:
Adam Robert Margetts - Columbus OH, US
Alton Shelbourne Keel - Melbourne FL, US
Assignee:
Thomson Licensing - Boulogne-Billancourt
International Classification:
H04B 1/00
US Classification:
375150, 375232, 375142, 375343, 375349, 708422, 708813
Abstract:
There is provided a hybrid rake/equalizer receiver for correlating a delay spread in a spread spectrum system. The hybrid rake/equalizer receiver includes a plurality of adaptive equalizers, each for filtering different regions of the delay spread that have an energy level above a pre-specified threshold to respectively provide equalized-descrambled chip sequences for correlation. Equalizer coefficients respectively corresponding to the plurality of adaptive equalizers are updated individually.

Multi-Stage Automatic Gain Control For Spread-Spectrum Receivers

View page
US Patent:
20040017865, Jan 29, 2004
Filed:
Jul 26, 2002
Appl. No.:
10/206690
Inventors:
Louis Litwin - Plainsboro NJ, US
Adam Margetts - Plainsboro NJ, US
Paul Knutson - Lawrenceville NJ, US
International Classification:
H04L027/08
US Classification:
375/345000, 375/147000
Abstract:
An apparatus and method for automatic gain control in spread-spectrum communications includes an automatic gain control apparatus for a spread-spectrum receiver, including a received signal strength indicator, an analog amplifier in signal communication with the received signal strength indicator, an analog-to-digital converter in signal communication with the analog amplifier, a digital automatic gain control loop in signal communication with the analog-to-digital converter, and a digital-to-analog converter in signal communication with the digital automatic gain control loop for providing a signal indicative of a digital gain to the analog amplifier; where the corresponding method for automatic gain control in spread-spectrum communications includes receiving an analog signal, measuring the strength of the received analog signal, deriving a first analog gain in correspondence with the measured strength, applying the derived first analog gain to an analog amplifier, deriving a second analog gain from a pilot channel signal within an automatic gain control loop, deriving a digital gain from the pilot channel signal within the automatic gain control loop, and applying an automatic gain control signal indicative of the second analog gain and the digital gain to the analog amplifier.

Multiuser Detection For High Capacity Cellular Downlink

View page
US Patent:
20170303244, Oct 19, 2017
Filed:
Oct 7, 2014
Appl. No.:
14/508686
Inventors:
William S. Song - Lexington MA, US
Adam R. Margetts - Westford MA, US
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
H04W 72/04
H04W 52/34
H04L 25/02
Abstract:
A system and method for decoding an intended transmission includes a user device that receives a downlink transmission containing a user signal intended for the user device and one or more interfering user signals directed to one or more other user devices. The user device obtains power stacking information that includes a power level for each of the user signals contained in the received downlink transmission. A channel is estimated using pilot signals in the downlink transmission. Each interfering user signal contained in the downlink transmission is demodulated and decoded using the power stacking information. The user device removes all interfering user signals from the received downlink transmission to obtain the user signal intended for the user device.
