A constrained optimization approach for an adaptive generalized subspace tracking algorithm
In this paper, we present a new algorithm for tracking the generalized signal subspace recursively. It is based on an interpretation of the generalized signal subspace as the solu...

A robust estimator and detector of circularity of complex signals
Recent research has revealed that circularity (or, propriety) of complex random signals can be exploited in developing optimal signal processors. In this paper, a robust estimator...

Iterative Correction of Clipped and Filtered Spatially Multiplexed OFDM Signals
— Peak-to-Average Power Ratio (PAPR) reduction in multicarrier systems with multiple transmit and receive antennas is considered. One attractive method for reducing the PAPR is t...
