Interative Decoding Based On Dominant Error Events

View page
US Patent:
6691263, Feb 10, 2004
Filed:
May 3, 2001
Appl. No.:
09/847953
Inventors:
Bane V. Vasic - Tucson AZ
Jeffrey L. Sonntag - Portland OR
Inkyu Lee - Kearny NJ
Assignee:
Agere Systems Inc. - Allentown PA
International Classification:
H03M 1341
US Classification:
714709, 714780, 714794
Abstract:
An iterative decoding system for intersymbol interference (ISI) channels has a module for extracting bit reliabilities from a partial response (PR) channel, an iterative decoder, and a module for updating the bit reliabilities. A transmitter parses a data sequence into blocks that are encoded to generate a sequence of codewords. By encoding, a correlation among the bits of each codeword output to the PR channel is created. A maximum likelihood sequence detector (MLSD) in the receiver produces estimates of transmitted bits from samples of the output from the PR channel. The MLSD detector has a priori knowledge of typical error events that can occur during transmission through the channel. Along with the bit estimates, at each time instant the MLSD detector generates set of error event likelihoods. These error event likelihoods are then converted into bit reliabilities that, together with estimates for the transmitted bits, are used to recalculate the bit reliabilities using the knowledge of the relation between bits within a codeword. The iterative decoder uses this soft input information (bit reliabilities and bit estimates) for each iteration of decoding to improve i) the estimate of the bit reliabilities, ii) the decisions of what bit has been transmitted, and iii) calculations for the error event likelihoods for the next iteration.

US Patent:
6909385, Jun 21, 2005
Filed:
Feb 27, 2002
Appl. No.:
10/084040
Inventors:
Bane Vasic - Tucson AZ, US
Erozan M. Kurtas - Pittsburgh PA, US
Assignee:
Seagate Technology LLC - Scotts Valley CA
International Classification:
H03M007/20
US Classification:
341102, 341 58, 341103
Abstract:
A method of encoding digital information in order to suppress dc includes the steps of receiving a sequence of m message bits of a message word, and mapping the sequence of m message bits of the message word to a codeword, of length n bits, generated from the m message bits using algebraic operations. Multiple codeword candidates are generated from the m message bits using the algebraic operations to combine the m message bits with different periodic scrambling sequences. One of the codeword candidates is selected for mapping based upon an optimizing criteria. Second order digital sum sequences, corresponding to each of the plurality of codeword candidates, can be used as the optimizing criteria to select the codeword.

US Patent:
7000168, Feb 14, 2006
Filed:
Mar 8, 2002
Appl. No.:
10/093926
Inventors:
Erozan M. Kurtas - Pittsburgh PA, US
Alexander Vasilievich Kuznetsov - Pittsburgh PA, US
Bane Vasic - Tucson AZ, US
Assignee:
Seagate Technology LLC - Scotts Valley CA
International Classification:
H03M 13/00
US Classification:
714755, 714800, 714801, 714804
Abstract:
A method of generating low density parity check codes for encoding data includes constructing a parity check matrix H from balanced incomplete block design (BIBD) in which a plurality B-sets which define the matrix have no more than one intersection point. The parity bits are then generated as a function of the constructed parity check matrix H.

System And Method For Iterative Decoding Of Reed-Muller Codes

View page
US Patent:
7331012, Feb 12, 2008
Filed:
Aug 5, 2003
Appl. No.:
10/634723
Inventors:
Bane Vasic - Tucson AZ, US
Jongseung Park - Pittsburgh PA, US
Erozan Mehmet Kurtas - Pittsburgh PA, US
Assignee:
Seagate Technology LLC - Scotts Valley CA
International Classification:
H03M 13/00
US Classification:
714781
Abstract:
A system for soft-decoding of Reed-Muller coded information has one or more rows of decoding blocks, each decoding block having a soft-output device and a Reed-Muller message passing device. A first soft-output device of a first decoding block processes a coded signal and a zero value probability vector. Each subsequent soft-output device processes the coded information and a non-zero value probability vector. The system for soft-decoding Reed-Muller coded information decodes a code-bit reliability vector from a soft-output device to generate an updated codeword reliability vector, which is used by a next decoding block in a sequence of decoding blocks to reprocess the coded information using the updated reliability vector. The reliability vector is updated through processing in each decoding block to optimize the reliability vector for extraction of the transmitted information from the received information.

Low Complexity Finite Precision Decoders And Apparatus For Ldpc Codes

View page
US Patent:
8458556, Jun 4, 2013
Filed:
Oct 8, 2010
Appl. No.:
12/900584
Inventors:
Shiva K. Planjery - Tucson AZ, US
Shashi Kiran Chilappagari - San Jose CA, US
Bane Vasic - Tucson AZ, US
David Declercq - Ableiges, FR
Assignee:
STMicroelectronics, SA - Montrouge
International Classification:
H03M 13/00
US Classification:
714752, 714755, 714758
Abstract:
In this invention, a new class of finite precision multilevel decoders for low-density parity-check (LDPC) codes is presented. These decoders are much lower in complexity compared to the standard belief propagation (BP) decoder. Messages utilized by these decoders are quantized to certain levels based on the number of bits allowed for representation in hardware. A message update function specifically defined as part of the invention, is used to determine the outgoing message at the variable node, and the simple min operation along with modulo 2 sum of signs is used at the check node. A general methodology is provided to obtain the multilevel decoders, which is based on reducing failures due to trapping sets and improving the guaranteed error-correction capability of a code. Hence these decoders improve the iterative decoding process on finite length graphs and have the potential to outperform the standard floating-point BP decoder in the error floor region. The description and apparatus of 3-bit decoders for column-weight three LDPC codes is also presented.

US Patent:
59635363, Oct 5, 1999
Filed:
Oct 28, 1997
Appl. No.:
8/962940
Inventors:
Bane V. Vasic - Rochester NY
Timothy J. Whitcher - Rochester NY
Yuan-Sheng Tyan - Webster NY
Randall H. Victora - Rochester NY
Assignee:
Eastman Kodak Company - Rochester NY
International Classification:
G11B 724
US Classification:
3692753
Abstract:
An optical recording medium comprising a first substrate with a center mounting hole and having top and bottom surfaces. At least one surface of the substrate is a prerecorded area wherein user data is provided and adapted to be read in an optical recording medium reader device. Over at least a portion of the substrate that can be read by the device is a photosensitive layer comprising a photosensitive material. When the photosensitive material is exposed to a predefined wavelength of light over a predetermined period of time the optical property of at least a portion of the material permanently changes. This change occurs after each copy of the prerecorded area is made. Thereby, the optical recording medium limits the authorized copies of the prerecorded area to a predetermined number.

Method For Insuring Uniqueness Of An Original Cd

View page
US Patent:
61886599, Feb 13, 2001
Filed:
Dec 15, 1998
Appl. No.:
9/211763
Inventors:
William J. Mueller - West Henrietta NY
Robert V. Reisch - Fairport NY
Bane V. Vasic - Allentown PA
Assignee:
Eastman Kodak Company - Rochester NY
International Classification:
G11B 700
US Classification:
369 59
Abstract:
The invention provides a method of proving that a CD is an authorized original by utilizing a unique catalog code that is stored in a sub channel data stream on the CD that is derived using digital signature techniques. The inputs for the unique catalog code are derived from a digital signature algorithm and include, in the case of audio CD, each song's ISRC number, a bar code or unique identifier of the CD and the audio data content. To verify that the CD is not a copy, the original digital signature algorithm used at the time of recording to create the unique catalog code is applied to the audio data and ISRC codes recorded on the disc to derive a catalog code. An authorized original CD will have the same catalog code value stored in the subchannel as the catalog code derived from the digital signature algorithm. If the catalog codes do not match, the disc is determined to be an illegal copy.
