Systems And Methods For Advanced Iterative Decoding And Channel Estimation Of Concatenated Coding Systems

View page
US Patent:
20160352463, Dec 1, 2016
Filed:
Aug 12, 2016
Appl. No.:
15/236066
Inventors:
- Palm Beach FL, US
Farnaz Shayegh - Montreal, CA
Hakan Dogan - Istanbul, TR
Wookwon Lee - Fairview PA, US
International Classification:
H04L 1/00
H03M 13/45
H04B 17/309
H03M 13/00
H03M 13/27
H03M 13/11
H03M 13/37
Abstract:
Systems and methods for decoding block and concatenated codes are provided. These include advanced iterative decoding techniques based on belief propagation algorithms, with particular advantages when applied to codes having higher density parity check matrices such as iterative soft-input soft-output and list decoding of convolutional codes, Reed-Solomon codes and BCH codes. Improvements are also provided for performing channel state information estimation including the use of optimum filter lengths based on channel selectivity and adaptive decision-directed channel estimation. These improvements enhance the performance of various communication systems and consumer electronics. Particular improvements are also provided for decoding HD radio signals, satellite radio signals, digital audio broadcasting (DAB) signals, digital audio broadcasting plus (DAB+) signals, digital video broadcasting-handheld (DVB-H) signals, digital video broadcasting-terrestrial (DVB-T) signals, world space system signals, terrestrial-digital multimedia broadcasting (T-DMB) signals, and China mobile multimedia broadcasting (CMMB) signals. These and other improvements enhance the decoding of different digital signals.

US Patent:
20140153625, Jun 5, 2014
Filed:
Dec 3, 2012
Appl. No.:
13/693023
Inventors:
- Palm Beach FL, US
Farnaz Shayegh - Montreal, CA
Hakan Dogan - Istanbul, TR
Wookwon Lee - Fairview PA, US
Assignee:
Digital PowerRadio, LLC - Palm Beach FL
International Classification:
G06F 11/16
US Classification:
375224, 375340, 375341
Abstract:
Systems and methods for decoding block and concatenated codes are provided. These include advanced iterative decoding techniques based on belief propagation algorithms, with particular advantages when applied to codes having higher density parity check matrices. Improvements are also provided for performing channel state information estimation including the use of optimum filter lengths based on channel selectivity and adaptive decision-directed channel estimation. These improvements enhance the performance of various communication systems and consumer electronics. Particular improvements are also provided for decoding HD Radio signals, including enhanced decoding of reference subcarriers based on soft-diversity combining, joint enhanced channel state information estimation, as well as iterative soft-input soft-output and list decoding of convolutional codes and Reed-Solomon codes. These and other improvements enhance the decoding of different logical channels in HD Radio systems.
