Distributed estimation over parallel fading channels with channel estimation error

open access: yes2008 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

Soft-Decision-Driven Channel Estimation for Pipelined Turbo Receivers [PDF]

open access: yes, 1999
We consider channel estimation specific to turbo equalization for multiple-input multiple-output (MIMO) wireless communication. We develop a soft-decision-driven sequential algorithm geared to the pipelined turbo equalizer architecture operating on ...

Distributed Estimation with Channel Estimation Error over Orthogonal Fading Channels

open access: yes2007 Conference Record of the Forty-First Asilomar Conference on Signals, Systems and Computers, 2007
We study distributed estimation of a source corrupted by an additive Gaussian noise and observed by sensors which are connected to a fusion center with unknown orthogonal (parallel) flat Rayleigh fading channels. The fading communication channels are estimated with training.

Channel Estimation Based on Statistical Frames and Confidence Level in OFDM Systems

open access: yesApplied 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 ...

Pilot design for underwater MIMO cosparse channel estimation based on compressed sensing

open access: yesInternational Journal of Distributed Sensor Networks, 2021
In multiple-input multiple-output–orthogonal frequency-division multiplexing underwater acoustic communication systems, the correlation of the sampling matrix is the key of the channel estimation algorithm based on compressed sensing. To reduce the cross-

Asymptotic Theory of Quantum Channel Estimation [PDF]

open access: yesPRX Quantum, 2021
The quantum Fisher information (QFI), as a function of quantum states, measures the amount of information that a quantum state carries about an unknown parameter. The (entanglement-assisted) QFI of a quantum channel is defined to be the maximum QFI of the output state assuming an entangled input state over a single probe and an ancilla.

On the relaxed maximum-likelihood blind MIMO channel estimation for orthogonal space-time block codes

open access: yes, 2020
This paper concerns the maximum-likelihood channel estimation for MIMO systems with orthogonal space-time block codes when the finite alphabet constraint of the signal constellation is relaxed.

Cramer-Rao bounds in the estimation of time of arrival in fading channels [PDF]

open access: yes, 2018
This paper computes the Cramer-Rao bounds for the time of arrival estimation in a multipath Rice and Rayleigh fading scenario, conditioned to the previous estimation of a set of propagation channels, since these channel estimates (correlation between ...
