Controlled Oscillator In A Digital Symbol Timing Recovery Network

View page
US Patent:
6445423, Sep 3, 2002
Filed:
Jul 9, 1999
Appl. No.:
09/351065
Inventors:
Aaron Reel Bouillet - Noblesville IN
David Glen White - Indianapolis IN
Assignee:
Thomson Licensing S.A. - Boulogne
International Classification:
H04N 5455
US Classification:
348537, 348726, 375321, 375326
Abstract:
A receiver for processing a VSB modulated signal containing terrestrial broadcast high definition television information includes an input analog-to-digital converter ( ) for producing a digital datastream. A symbol timing recovery and segment sync recovery network ( ; FIG. ) develops a properly timed sampling clock for the digital converter ( ). The symbol timing recovery network ( ) responds to an output from the segment sync recovery network ( ), which in turn responds to an equalized signal from an adaptive channel equalizer ( ). A controlled oscillator ( ) generates the sampling clock for the digital converter. A control network ( ; FIG. ) shifts the frequency range of the oscillator to maintain desired linear operation to enhance symbol timing acquisition.

Adaptive Channel Equalizer

US Patent:
6490007, Dec 3, 2002
Filed:
May 5, 2000
Appl. No.:
09/566159
Inventors:
Aaron Reel Bouillet - Noblesville IN
Matthew Thomas Mayer - Indianapolis IN
John Sidney Stewart - Indianapolis IN
Assignee:
Thomson Licensing S.A. - Boulogne
International Classification:
H04N 521
US Classification:
348614, 348726, 375232
Abstract:
In a receiver for processing a VSB modulated signal containing terrestrial broadcast high definition television information including data packets, the received signal is converted to a digital signal ( ), demodulated ( ) and equalized by an adaptive channel equalizer ( ). An equalized signal is processed by decoding networks including a Reed-Solomon FEC error detecting and correcting network ( ). The equalizer filter coefficient step size is dynamically adjusted during the adaption process as a function of the packet error rate. A local microcontroller ( ) monitors the packet error rate at the Reed-Solomon error detector and instructs the equalizer to adjust the coefficient step size in a direction to reduce the packet error rate.

Selective Gain Adjustment To Aid Carrier Acquisition In A High Definition Television Receiver

View page
US Patent:
6985192, Jan 10, 2006
Filed:
Jul 13, 2000
Appl. No.:
10/031020
Inventors:
Aaron Reel Bouillet - Noblesville IN, US
John Sidney Stewart - Indianapolis IN, US
Assignee:
Thomson Licensing - Boulogne-Billancourt
International Classification:
H04N 5/50
US Classification:
348735, 348725, 348731, 348678
Abstract:
In a receiver for processing a vestigial sideband modulated signal containing terrestrial broadcast high definition television information and a pilot component, and for which multipath interference can lead to significant attenuation within narrow bands of the received signal spectrum containing the pilot tone of an Advanced Television Systems Committee high definition television broadcast signal, it has been found desirable to amplify the input signal in order to achieve synchronization of the receiver's phase-locked loop to the received pilot tone. Once this initial acquisition has been established, the amplification applied to the received signal can be reduced to a level appropriate for remaining blocks in the demodulation chain without upsetting the pilot tone synchronization. Thus, according to the present invention, the gain applied to the received ATSC VSB signal is set higher during pilot tone acquisition than it is during the remaining stages of demodulation.

Multipath Signal Strength Indicator

US Patent:
7116703, Oct 3, 2006
Filed:
Oct 15, 2002
Appl. No.:
10/270764
Inventors:
Aaron Reel Bouillet - Noblesville IN, US
Matthew Thomas Mayer - Indianapolis IN, US
Assignee:
Thomson Licensing - Boulogne-Billancourt
International Classification:
H04B 1/707
H04B 1/10
H03H 7/30
US Classification:
375148, 375232, 375346
Abstract:
A multipath signal strength indicator is included in a communications receiver which is responsive to a communications channel subject to a multipath signal. The multipath signal strength indicator includes circuitry for estimating the characteristics of the communications channel and circuitry for storing nominal characteristics of a communications channel free of the multipath signal. Further circuitry calculates the difference between the nominal characteristic and the estimated channel characteristic as the multipath signal strength.

Channel Acquisition Processing For A Television Receiver

US Patent:
7230654, Jun 12, 2007
Filed:
Apr 14, 2003
Appl. No.:
10/511645
Inventors:
Weixiao Liu - Indianapolis IN, US
Aaron Reel Bouillet - Noblesville IN, US
Matthew Thomas Mayer - Indianapolis IN, US
Assignee:
Thomson Licensing - Boulogne-Billancourt
International Classification:
H04N 5/455
US Classification:
348726, 348725, 348731, 375324, 375326
Abstract:
Channel acquisition in a digital television signal receiver is improved by determining the carrier tracking loop frequency offsets and the symbol timing recovery offsets for each channel in the television receiver. Offsets are stored in respective EEPROMs for each channel. When a channel is to be acquired in the TV receiver the tune command will be applied to the appropriate EEPROMs and the respective values are conveyed to the VSB demodulator to start acquisition of the channel.

System For Detecting The Characteristics Of A Time Varying Multipath Component

US Patent:
7366265, Apr 29, 2008
Filed:
Aug 29, 2002
Appl. No.:
10/232789
Inventors:
Aaron Reel Bouillet - Noblesville IN, US
Assignee:
Thomson Licensing - Boulogne, Billancourt
International Classification:
H04B 7/10
US Classification:
375347
Abstract:
A system for receiving a composite signal including a main component and a multipath component includes a demodulator chain having adaptive circuitry controllable in response to a control signal to compensate for the multipath component. In this system, a control signal generator includes a phase error estimator, which generates a signal representing an estimate of the phase error between the received main component and the received multipath component. A controller generates the control signal in responsive to the phase error signal.

Symbol Timing Search Algorithm

US Patent:
7469027, Dec 23, 2008
Filed:
Oct 18, 2004
Appl. No.:
10/511640
Inventors:
Weixiao Liu - Charlottesville VA, US
Aaron Reel Bouillet - Noblesville IN, US
Matthew Thomas Mayer - Indianapolis IN, US
Assignee:
Thomson Licensing - Boulogne-Billancourt
International Classification:
H04L 7/00
US Classification:
375355
Abstract:
A system is described for establishing timing synchronism between a local receiver symbol clock and a transmitter symbol clock. A prescribed number of offset values are calculated for desired symbol timing range, the offset values being grouped substantially symmetrically about a central offset value. Each of the preselected offset values are tested to see if symbol timing recovery lock can be achieved by starting at the central offset value and gradually moving away from such value. Finally, two timing detection algorithms are used and switched between the two algorithms is carried out as desired to maximize the possibility of STR lock.
