In this work, expectation-maximization type receiver for uplink of an MC-CDMA system based on a time sharing hopped communication technique is proposed in order to cope with the multipath fading effect in a wireless communication system. In the proposed time-sharing hopped communication method, managing mechanism determines each user channel quality knowledge by controlling the quality of the channels...
This paper presents a numerical Bayesian approach for the direction-of-arrival (DOA) tracking of multiple targets using a linear and passive sensor array. In this paper, support vector regression (SVR) method is employed, together with particle filters (PFs), to obtain an effective proposed distribution utilizing observed phenomena to propose a new sample. Two PF algorithms are presented: One is based...
In this paper, we address the problem of joint tracking of the direction of arrival (DOA) and range parameters of moving sources in the near-field of an antenna array with the expectation-maximization (EM) based recursive algorithm. The main characteristic of the proposed recursive EM approach is to include computation of the gradient of the log-likelihood and some form of the complete-data fisher...
In this paper, maximum likelihood (ML) estimator is proposed for the joint estimation of the direction of arrival (DOA) and range parameters of moving sources in the near-field of the antenna array. ML estimation algorithm is presented for deterministic signal model. Recursive form of the expectation maximization (REM) algorithm is suggested for the estimation of the near-field parameters because...
This paper addresses the problem of applying powerful statistical pattern classification algorithms based on kernels to target tracking. Rather than directly adapting a recognizer, we develop a localizer directly using the regression form of the support vector machines (SVM). The proposed approach considers using dynamic model together as feature vectors and makes the hyperplane and the support vectors...
