Maximum Likelihood Decoding Via Mixed-Integer Adaptive Linear Programming

View page
US Patent:
7945845, May 17, 2011
Filed:
Jun 19, 2007
Appl. No.:
11/764938
Inventors:
Stark C. Draper - Newton MA, US
Jonathan S. Yedidia - Cambridge MA, US
Assignee:
Mitsubishi Electric Research Laboratories, Inc. - Cambridge MA
International Classification:
H03M 13/03
US Classification:
714794, 714769, 714755
Abstract:
A method and system decode a sequence of symbols received via a channel to a codeword of an error-correcting code. Log-likelihood ratios are determined from a sequence of symbols received via a channel. A set of constraints is initialized according to the log-likelihood ratios. An adaptive linear programming decoder is applied to the set of constraints and the log- likelihood ratios according to an error-correcting code to produce an estimate of the codeword and an updated set of constraints. If the estimate of the codeword is a non-integer pseudo codeword, further update the set of updated constraints with a set of integer constraints if the estimate of the codeword is the non-integer pseudo codeword, and proceeding with the applying step, and otherwise producing the estimate of the codeword as the final codeword.

Method For Constructing Large-Girth Quasi-Cyclic Low-Density Parity-Check Codes

View page
US Patent:
8103931, Jan 24, 2012
Filed:
Aug 27, 2008
Appl. No.:
12/199512
Inventors:
Yige Wang - Natick MA, US
Jonathan S. Yedidia - Cambridge MA, US
Stark C. Draper - Madison WI, US
Assignee:
Mitsubishi Electric Research Laboratories, Inc. - Cambridge MA
International Classification:
H03M 13/00
US Classification:
714755, 714786
Abstract:
A method constructs a code, wherein the code is a large-girth quasi-cyclic low-density parity-check code. A base matrix is selected for the code. A cost matrix corresponding to the base matrix is determined. A single element in the base is changed repeatedly maximize a reduction in cost. A parity check matrix is constructing for the code from the base matrix when the cost is zero, and an information block is encoded as a code word using the parity check matrix in an encoder.

Multi-Stage Decoder For Error-Correcting Codes

View page
US Patent:
8261170, Sep 4, 2012
Filed:
Jan 27, 2009
Appl. No.:
12/360832
Inventors:
Jonathan S. Yedidia - Cambridge MA, US
Yige Wang - Natick MA, US
Stark C. Draper - Madison WI, US
Assignee:
Mitsubishi Electric Research Laboratories, Inc. - Cambridge MA
International Classification:
H03M 13/03
US Classification:
714794
Abstract:
A multi-stage decoder decodes a block of symbols, received via a noisy channel, to a codeword. The decoder includes multiple sub-decoders connected sequentially, and wherein a next sub-decoder has a slower processing time and better word error rate than a previous sub-decoder, and wherein the next sub-decoder is only executed if the previous decoder fails to decode the block sequence of symbols, and a last sub-decoder is executed until a termination condition is reached.

Pre-Processing Biometric Parameters Before Encoding And Decoding

View page
US Patent:
8375218, Feb 12, 2013
Filed:
Oct 30, 2007
Appl. No.:
11/928687
Inventors:
Jonathan S. Yedidia - Cambridge MA, US
Stark C. Draper - Madison WI, US
Yagiz Sutcu - Arlington MA, US
Anthony Vetro - Arlington MA, US
Assignee:
Mitsubishi Electric Research Laboratories, Inc. - Cambridge MA
International Classification:
G06F 21/00
US Classification:
713186, 709248
Abstract:
Biometric parameters acquired from human faces, voices, fingerprints, and irises are used for user authentication and access control. Because the biometric parameters are continuous and vary from one reading to the next, syndrome codes are applied to determine biometric syndrome vectors. The biometric syndrome vectors can be stored securely, while tolerating an inherent variability of biometric data. The stored biometric syndrome vector is decoded during user authentication using biometric parameters acquired at that time. The syndrome codes can also be used to encrypt and decrypt data. The biometric parameters can be pre-processed to form a binary representation, in which the binary representation has a set of predetermined statistical properties enforced imposed by a set of binary logical conditions.

Method And System For Decoding Graph-Based Codes Using Message-Passing With Difference-Map Dynamics

View page
US Patent:
8407550, Mar 26, 2013
Filed:
Aug 14, 2009
Appl. No.:
12/541810
Inventors:
Jonathan S. Yedidia - Cambridge MA, US
Yige Wang - Natick MA, US
Stark C. Draper - Madison WI, US
Assignee:
Mitsubishi Electric Research Laboratories, Inc. - Cambridge MA
International Classification:
G06F 11/00
US Classification:
714752, 714774
Abstract:
A code to be decoded by message-passing is represented by a factor graph. The factor graph includes variable nodes indexed by i and constraint nodes indexed by a connected by edges for transferring messages moutgoing from the variable nodes to the constraint nodes and messages mincoming from the constraint nodes to the variable nodes. The messages mare initialized based on beliefs bof a received codeword. The messages mare generated by overshooting the messages mat the constraint nodes. The beliefs bare updated at the variable nodes using the messages m. The codeword is outputted if found, otherwise, the messages mare updated using a correction for the overshooting.

System And Method For Determining Quasi-Cyclic Low-Density Parity-Check Codes Having High Girth

US Patent:
8499218, Jul 30, 2013
Filed:
Sep 30, 2011
Appl. No.:
13/251143
Inventors:
Jonathan Yedidia - Cambridge MA, US
Stark Draper - Madison WI, US
Yige Wang - Shrewsbury MA, US
Assignee:
Mitsubishi Electric Research Laboratories, Inc. - Cambridge MA
International Classification:
H03M 13/00
US Classification:
714758, 714752, 714755
Abstract:
A method estimates parameters of 3-phase voltage signals to synchronize a power grid in a presence of a voltage unbalance by transforming the 3-phase voltage signals to αβ-reference signals using a Clarke transformation matrix, and estimating sinusoidal signals and corresponding quadrature signals of the αβ-reference signals using an extended Kalman filter, and determining a phase angle of a positive sequence based on a relationship of the phase angle to the estimated the sinusoidal signals.

Biometric Based User Authentication And Data Encryption

US Patent:
20070174633, Jul 26, 2007
Filed:
Nov 29, 2006
Appl. No.:
11/564638
Inventors:
Stark Draper - Newton MA, US
Ashish Khisti - Cambridge MA, US
Emin Martinian - Arlington MA, US
Anthony Vetro - Arlington MA, US
Jonathan Yedidia - Cambridge MA, US
International Classification:
H04L 9/00
H04K 1/00
US Classification:
713186000, 713181000, 713183000
Abstract:
Biometric parameters acquired from human forces, voices, fingerprints, and irises are used for user authentication and access control. Because the biometric parameters are continuous and vary from one reading to the next, syndrome codes are applied to determine biometric syndrome vectors. The biometric syndrome vectors can be stored securely while tolerating an inherent variability of biometric data. The stored biometric syndrome vector is decoded during user authentication using biometric parameters acquired at that time. The syndrome codes can also be used to encrypt and decrypt data.

Cooperative Routing In Wireless Networks Using Mutual-Information Accumulation

View page
US Patent:
20080144562, Jun 19, 2008
Filed:
Feb 29, 2008
Appl. No.:
12/039843
Inventors:
Stark C. Draper - Madison WI, US
Lingjia Liu - College Station TX, US
Andreas F. Molisch - Arlington MA, US
Jonathan S. Yedidia - Cambridge MA, US
International Classification:
H04B 7/14
H04L 12/56
US Classification:
370315, 370400
Abstract:
A route is selected in a wireless cooperative relay network of nodes. A decoding order is initialized. A set of resources is minimized subject to constraints. The resources are allocated to the nodes in the decoding order. The decoding order is changed iteratively to further minimize the allocated resources, until a minimum is reached. A code word is transmitted when the allocated resources are at the minimum, which can either be determined globally or locally at each node. The method can operate in a centralized or distributed manner.
