Closed Loop Adaptive Clock Rfi Mitigation

View page
US Patent:
7804920, Sep 28, 2010
Filed:
Mar 30, 2007
Appl. No.:
11/694171
Inventors:
Michael E. Deisher - Hillsboro OR, US
Keith R. Tinsley - Beaverton OR, US
Chaitanya Sreerama - Hillsboro OR, US
Assignee:
Intel Corporation - Santa Clara CA
International Classification:
H04B 1/10
US Classification:
375346, 455296
Abstract:
A method according to one embodiment for mitigating radio frequency interference by identifying system clocks, identifying active radio channels, measuring clock harmonics in or near the active radio channels, determining potential interference occurring if the clocks were moved to new fundamental frequencies, and shifting clock fundamental frequencies to reduce interference to the active radio channels based on existing interference and the potential interference of a plurality of new fundamental frequencies. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

Adaptive Control Of Clock Spread To Mitigate Radio Frequency Interference

US Patent:
7907694, Mar 15, 2011
Filed:
Sep 24, 2007
Appl. No.:
11/860374
Inventors:
Harry Skinner - Portland OR, US
Michael E. Delsher - Hillsboro OR, US
Chaitanya Sreerama - Hillsboro OR, US
Assignee:
Intel Corporation - Santa Clara CA
International Classification:
H04L 7/00
US Classification:
375371, 375376, 375373, 375294, 375215
Abstract:
In some embodiments an adaptive clocking controller determines a clock spread of a system clock that would result in a lowest total interference between a channel received by a radio receiver and the system clock. A clock generator modifies a spread of the system clock in response to the determined clock spread. Other embodiments are described and claimed.

US Patent:
8385485, Feb 26, 2013
Filed:
Feb 1, 2011
Appl. No.:
13/018725
Inventors:
Harry Skinner - Portland OR, US
Michael E. Deisher - Hillsboro OR, US
Chaitanya Sreerama - Hillsboro OR, US
Assignee:
Intel Corporation - Santa Clara CA
International Classification:
H03D 1/04
US Classification:
375346, 375371, 375376, 375373, 375294, 375215
Abstract:
In some embodiments an adaptive clocking controller determines a clock spread of a system clock that would result in a lowest total interference between a channel received by a radio receiver and the system clock. A clock generator modifies a spread of the system clock in response to the determined clock spread. Other embodiments are described and claimed.

Dynamic Rfi Detection Using Signal Strength Values

View page
US Patent:
8433248, Apr 30, 2013
Filed:
Jun 8, 2009
Appl. No.:
12/480092
Inventors:
Chaitanya Sreerama - Hillsboro OR, US
Harry G. Skinner - Beaverton OR, US
Assignee:
Intel Corporation - Santa Clara CA
International Classification:
H04B 1/00
H04B 15/00
H04B 17/00
US Classification:
455 631, 455 6713
Abstract:
An apparatus may include a radio interface to receive a plurality of signal strength values of a radio. An interference module can identify a radio frequency interference impact on the radio based on the plurality of signal strength values. In one embodiment, the radio interface issues a plurality of interference calls to the radio, where each of the plurality of signal strength values corresponds to an interference call.

Radio Frequency Interference Sensing System And Method

View page
US Patent:
8483621, Jul 9, 2013
Filed:
Jul 1, 2008
Appl. No.:
12/166168
Inventors:
Chaitanya Sreerama - Hillsboro OR, US
Keith R. Tinsley - Beaverton OR, US
Srikathyayani Srikanteswara - Portland OR, US
Assignee:
Intel Corporation - Santa Clara CA
International Classification:
H04B 15/00
H04B 17/00
US Classification:
455 6713, 455296
Abstract:
A method of sensing radio frequency interference (RFI) in a wireless system is provided. The method includes receiving wireless data through a wireless receiver and evaluating received wireless data through a receiver baseband module to identify an occurrence of a signal detection failure by a physical (PHY) layer or a media access control (MAC) layer of the wireless system. The method also includes triggering a radio frequency interference sensing state in response to the occurrence of signal detection failure by the physical layer or the media access control layer of the wireless system.

Dynamic Rfi Mitigation

US Patent:
8611478, Dec 17, 2013
Filed:
Dec 18, 2008
Appl. No.:
12/317024
Inventors:
Chaitanya Sreerama - Hillsboro OR, US
Keith R. Tinsley - Beaverton OR, US
Harry G. Skinner - Beaverton OR, US
Assignee:
Intel Corporation - Santa Clara CA
International Classification:
H03D 1/04
US Classification:
375346
Abstract:
Provided herein are different embodiments for performing radio frequency interference (RFI) mitigation in electronic devices such as mobile computing systems. In some embodiments, a dynamic RFI mitigation scheme allows for monitoring of wireless channels for RFI and to adaptively shift an identified RFI source (e. g. , system clock) harmonics, e. g. , either out of the on-channels or to a neutral position within the on-channels such as by using cost-function analysis.
