Zero-forcing blind equalization based on subspace estimation for multiuser systems.

Zero-forcing blind equalization based on subspace estimation for multiuser systems.

Input signal recovery from frequency-selective fading channels is a problem of great theoretical and practical importance. We present several new blind algorithms that utilize second-order statistics for direct multichannel equalization. The algorithms are based on the subspace extraction of a prese...
