Blind channel estimation using the second-order statistics: algorithms
Most second-order moment-based blind channel estimators belong to two categories: i) optimal correlation/spectral fitting techniques and ii) eigenstructure-based techniques. These two classes of algorithms have complementary advantages and disadvantages. In this paper, a new optimization criterion referred to as the joint optimization with subspace constraints (JOSC) is proposed to unify the tw...
متن کاملBlind channel estimation using the second-order statistics: asymptotic performance and limitations
In this paper, we consider the asymptotic performance and fundamental limitations of the class of blind estimators that use the second-order statistics. An achievable lower bound of the asymptotic normalized mean-square error (ANMSE) is derived. It is shown that the achievable ANMSE is lower bounded by the condition number of the Jacobian matrix of the correlation function with respect to the c...
متن کاملBlind Channel Equalization for Siso and Simo Channels Using Second Order Statistics Blind Channel Equalization for Siso and Simo Channels Using Second Order Statistics
In this thesis we develop several approaches to the problem of blind channel equalization based on second-order statistics (808). We consider the single-input singleoutput (8180) system with minimum phase channel where the received signal is sampled at the symbol rate (T-spaced equalizer). We formulate the equalizer design criterion as a simple convex optimization problem, where the equalizer c...
متن کاملSecond order statistics based blind channel equalization with correlated sources
ABSTRACT In this paper the blind equalization method of Tong, Xu and Kailath, which was derived under the assumption of a white transmitted sequence, is generalized in order to include correlated sources. The resulting algorithm can be applied to arbitrarily colored sources, assuming that the source second-order statistics are known. Because it makes explicit use of this information, the new al...
متن کاملBlind and semi-blind channel identification methods using second order statistics for OFDM systems
In this paper two new blind channel identification methods suited to multicarrier system (OFDM) exploiting the redundancy introduced by the adjunction of a cyclic prefix at the emitter and relying on the evaluation of the received signal autocorrelation matrix are presented. The proposed algorithms are able to identify any channel without any constraint on their zeroes location (including non-m...
