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.

Data-derived iterative channel estimation with channel tracking for a mobile fourth generation wide area OFDM system [PDF]
, 2003 In this paper an iterative channel estimation technique for a mobile fourth generation coherent orthogonal frequency division multiplexing (OFDM) system is proposed. Coherent detection dictates that a per-subband estimate of the frequency response of the

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.
