Capacity bounds for an ultra-wideband channel model
(IEEE, 2004-10)There is an ongoing effort by the IEEE 802.15.3a subcommittee to reach a UWB personal area network standard. We estimate the achievable rates for such networks using a channel model specified by the same group. The analysis ... -
Compressive sampling and adaptive multipath estimation
(IEEE, 2010)In many signal processing problems such as channel estimation and equalization, the problem reduces to a linear system of equations. In this proceeding we formulate and investigate linear equations systems with sparse ... -
Çok kullanıcılı çok antenli sistemlerde iş birlikli iletim
(IEEE, 2008-04)Bu çalışmada işbirlikli, çok kullanıcılı, ve çok antenli bir haberleşme sisteminde telsiz erişim terminallerinin en iyi veri iletimi tekniğine ortaklaşa karar vermeleri problemini inceliyoruz. Burada pek çok çalışmadan ... -
Detection of sparse targets with structurally perturbed echo dictionaries
(Elsevier, 2013)In this paper, a novel algorithm is proposed to achieve robust high resolution detection in sparse multipath channels. Currently used sparse reconstruction techniques are not immediately applicable in multipath channel ... -
Nondata-aided channel estimation for OFDM systems with space-frequency transmit diversity
(Institute of Electrical and Electronics Engineers, 2006)This paper proposes a computationally efficient nondata-aided maximum a posteriori (MAP) channel-estimation algorithm focusing on the space-frequency (SF) transmit diversity orthogonal frequency division multiplexing (OFDM) ... -
Recovery of sparse perturbations in Least Squares problems
(IEEE, 2011)We show that the exact recovery of sparse perturbations on the coefficient matrix in overdetermined Least Squares problems is possible for a large class of perturbation structures. The well established theory of Compressed ...
