Maximum likelihood decoding for multilevel channels with gain and offset mismatch
[article]
2015
arXiv
pre-print
Preserved Fulltext
Immink and J.H. Weber recently defined and studied a channel with both gain and offset mismatch, modelling the behaviour of charge-leakage in flash memory. ...
The paper derives a formula for maximum likelihood decoding for this channel, and also defines and justifies a notion of minimum distance of a code in this context. ...
Acknowledgements The author would like to thank Alexey Koloydenko for fruitful discussions on maximum likelihood estimation, and Kees S. ...

OFDM system loses the orthogonality between subcarriers due to carrier frequency offset resulting in inter-carrier interference (ICI) in the OFDM system. ...
In the proposed scheme, the estimation of CFO is performed using the Extended Kalman filter (EKF) and sigma pointed Kalman filter (SPKF) on the SCM-OFDM system. ...
To mitigate the ICI, Carrier Frequency Offset(CFO) is necessary, CFO estimation using the Maximum Likelihood estimator is proposed in [9] , which increases the complexity of the receiver with an increase ...
