Blind adaptive multiuser detection in multipath CDMA channels based on subspace tracking
Xiaodong Wang,H.V. Poor +1 more
TL;DR: It is shown that through the use of signal subspace estimation, both the decorrelating filterbank and the linear MMSE filterbank can be obtained blindly, i.e., they can be estimated from the received signal with the prior knowledge of only the signature waveform of the desired user.

Plane rotation-based EVD updating schemes for efficient subspace tracking
Benoit Champagne,Qing-Guang Liu +1 more
TL;DR: New algorithms based on plane rotations for tracking the eigenvalue decomposition (EVD) of a time-varying data covariance matrix are presented, which directly produce eigenvectors in orthonormal form and are well suited for the application of subspace methods to nonstationary data.
Performance analysis of an adaptive algorithm for tracking dominant subspaces
TL;DR: It is shown that even though the algorithm does not constrain W to have orthonormal columns, there is deviation from orthonormality of the first order and the asymptotic distributions have a structure that is very similar to those describing batch estimation techniques because both algorithms are obtained from the minimization of the same criterion.

An H/spl infin/ approach to multi-source tracking
Tharmalingam Ratnarajah
- 12 May 1998
TL;DR: A novel H/spl infin/ approach is proposed for tracking of polarized co-channel sources using an array of tripole antennas that is capable of handling the tracking of appearing/disappearing sources during the observation interval and can accommodate array modeling uncertainties.

Multiple emitter location and signal parameter estimation
TL;DR: In this article, a description of the multiple signal classification (MUSIC) algorithm, which provides asymptotically unbiased estimates of 1) number of incident wavefronts present; 2) directions of arrival (DOA) (or emitter locations); 3) strengths and cross correlations among the incident waveforms; 4) noise/interference strength.
