Abbasfar, A.; Divsalar, D.; Yao, K., 2004, "Accumulate repeat accumulate codes", https://hdl.handle.net/2014/8047, ['2004 IEEE International Symposium on Information Theory', 'Chicago, IL, USA'], JPL Open Repository
In this paper we propose an innovative channel coding scheme called Accumulate Repeat Accumulate codes. This class of codes can be viewed as trubo-like codes, namely a double serial concatenation of a rate-1 accumulator as an outer code, a regular or irregular repetition as a mid... |

Abbasfar, A.; Divsalar, D.; Yao, K., 2004, "Maximum likelihood decoding analysis of accumulate-repeat-accumulate codes", https://hdl.handle.net/2014/8046, ['2004 IEEE International Symposium on Information Theory', 'Chicago, IL, USA'], JPL Open Repository
In this paper, the performance of the repeat-accumulate codes with (ML) decoding are analyzed and compared to random codes by very tight bounds. Some simple codes are shown that perform very close to Shannon limit with maximum likelihood decoding. |

Ansar, A.; Castano, A.; Matthies, L., 2004, "Enhanced real-time stereo using bilateral filtering", https://hdl.handle.net/2014/8040, ['IEEE Conference on Computer Vision and Pattern Recognition', 'Washington D.C., USA'], JPL Open Repository
We show that in conjunction with SAD correlation, our new method improves stereo quality at range discontinuities while maintaining real-time performance. |
