Energy-Efficient Channel Estimation [PDF]
IEEE Access, 2020 We investigate the energy-efficient channel estimation in wireless networks, where one pilot is inserted for every several data slots to estimate the channel coefficients. Both the channel state information estimation error and the time-varying model are considered. We first formulate the energy-efficient channel estimation problem into a mixed integer

Channel Estimation for Spatial Modulation [PDF]
IEEE Transactions on Communications, 2014 In this paper, a novel channel estimation (CE) method is proposed for spatial modulation (SM), a unique single-stream multiple-input-multiple-output transmission technique. In SM, there is only one transmit antenna being active at any time instance. While this property completely avoids inter-channel interference, it results in a challenge to estimate ...

Distributed estimation over parallel fading channels with channel estimation error
2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008 We consider distributed estimation of a source observed by sensors in additive Gaussian noise, where the sensors are connected to a fusion center with unknown orthogonal (parallel) flat Rayleigh fading channels. We adopt a two-phase approach of (i) channel estimation with training, and (ii) source estimation given the channel estimates, where the total

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

Channel estimation with noisy entanglement [PDF]
Physics Letters A, 2001 We analyze the Pauli-channel estimation with mixed nonseparable states. It turns out that within a specific range entanglement can serve as a nonclassical resource. However, this range is rather small, that is entanglement is not very robust for this application.
