Abstract: channel estimation is an essential component in applications such as radar and data communication in multi path time varying environments, it is necessary to estimate time-shifts, scale-shifts (the wideband equivalent of doppler-shifts), and the gains/phases of each of the multiple paths. For the channel estimation the adaptive-least absolute shrinkage and selection oper- ator (a-lasso) algorithm is used to leverage channel sparsity during the estimation 13. It leads to various applications such as multiple kernel learning [2], microarray data analysis [3], channel estimation in doubly dispersive multicarrier systems [4], etc the group sparse reconstruction problem has.

Mtechthesis abstract 2015 8 sbl based joint sparse channel estimation and maximum without channel estimation for ofdm. Nevertheless, in sparse channel estimation, when pilot positions are really close to each other, pilot pattern efficiency and accuracy of channel estimation are very depressed thus, the second algorithm is offered.

  • In communication systems, efficient use of the spectrum is an indispensable concern recently the use of compressed sensing for the purpose of estimating orthogonal frequency division multiplexing (ofdm) sparse multipath channels has been proposed to decrease the transmitted overhead in form of the pilot subcarriers which are essential for channel estimation.
  • Super-resolution sparse mimo-ofdm channel estimation based on spatial and temporal correlations (2014) abstract : this letter proposes a parametric sparse multiple input multiple output (mimo)-ofdm channel estimation scheme based on the finite rate of innovation (fri) theory, whereby super-resolution estimates of path delays with arbitrary values can be achieved.
  • In this thesis, the estimation process is done using non-orthogonal sequences with low correlation and it is compared to the traditional estimation methods the sparse character.

Estimation approach consisting of the mst detection and the sparse channel estima­ tion, both in a semi-blind fashion, is developed an intensive simulation study of all. The rich multipath coupled with the fine time resolution of the uwb signals create a challenging sparse channel estimation problem this master thesis examines the use of cs in the estimation of highly sparse channel by means of a new sparse channel estimation approach based on the frequency domain model of the uwb signal. This thesis deals with sparse bayesian learning (sbl) with application to radio channel estimation as opposed to the classical approach for sparse signal representation, we focus on the problem of inferring complex signals.
