Channel Estimation Based on Statistical Frames and Confidence Level in OFDM Systems
Applied Sciences, 2018 Channel estimation is an important module for improving the performance of the orthogonal frequency division multiplexing (OFDM) system. The pilot-based least square (LS) algorithm can improve the channel estimation accuracy and the symbol error rate ...

The Extended-Window Channel Estimator for Iterative Channel-and-Symbol Estimation
EURASIP Journal on Wireless Communications and Networking, 2005 L'application de l'algorithme de maximisation des attentes (EM) à l'estimation des canaux aboutit à un estimateur itératif de canaux et de symboles (ICSE) bien connu. L'EM-ICSE itère entre un estimateur de symbole basé sur la récursivité avant-arrière (égaliseur BCJR) et un estimateur de canal, et peut fournir des estimations approximatives de canal ...

Improved Channel Occupancy Rate Estimation [PDF]
IEEE Transactions on Communications, 2015 Channel occupancy rate (COR) is the fraction of the time that a channel is occupied, i.e., contains signal(s) in addition to noise. Estimation of COR is important, e.g., in cognitive radio systems, which can use this information for intelligently adapting their spectrum use to the operating environment.

Histogram-based Flash channel estimation [PDF]
2015 IEEE International Conference on Communications (ICC), 2015 Current generation Flash devices experience significant read-channel degradation from damage to the oxide layer during program and erase operations. Information about the read-channel degradation drives advanced signal processing methods in Flash to mitigate its effect.
