Modified Kalman Filters for Channel Estimation in Orthogonal Space-Time Coded Systems
(Ieee-inst Electrical Electronics Engineers IncPiscatawayEUA, 2012)
Energy-efficient estimation of a MIMO channel
Abstract Exploiting the benefits of multiple antenna technologies is strongly conditioned on knowledge of the wireless channel that affects the transmissions. To this end, various channel estimation algorithms ...
ESQUEMA DE COMUNICAÇÃOMIMO PARA QUATRO ANTENAS TRANSMISSORAS E TAXA DE TRANSMISSÃO UNITÁRIA: ANÁLISE DE DESEMPENHO E DE ROBUSTEZ
(Universidade Federal de Santa MariaBRCiência da ComputaçãoUFSMPrograma de Pós-Graduação em Informática, 2014-01-31)
In this master thesis it is proposed a MIMO communication scheme with four transmit antennas and unitary transmission rate. The performance and robustness of the scheme are evaluated and compared with other good proposals ...
Maximum Likelihood Estimator For The Alpha-eta-mu Fading Environment

MIMO millimeter-wave channel estimation using coalitional games
In millimeter-wave massive multiple input multiple output (MIMO) antenna systems, channel estimation is a crucial component. In this paper, we propose a virtual channel representation channel estimation method us-ing ...
Jointly multi-user detection and channel estimation with genetic algorithm
This work aims at proposing the use of the evolutionary computation methodology in order to jointly solve the multiuser channel estimation (MuChE) and detection problems at its maximum-likelihood, both related to the direct ...
An Alternative Look at the Constant-Gain Kalman Filter for State Estimation Over Erasure Channels
This technical note studies state estimation problems subject to data loss. We consider a class of switched estimators, where missing data is replaced by optimal estimates. The considered class of estimators encompasses a ...
Telephone Channel Compensation in Speaker Verification Using a Polynomial Approximation in the Log-Filter-Bank Energy Domain
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2012-01)
This correspondence presents a novel feature-space channel compensation technique that models the convolutional distortion in the log-energy mel-filter domain by means of a polynomial approximation. The proposed parametric ...
