Statistical Methods for Soft Detection in Multiuser and Multiple Antenna Communication Systems

Invention SummaryA key benefit of MIMO systems is the ability to simultaneously transmit multiple quadrature amplitude modulated (QAM) symbols through a multitude of antennas. The multiple symbols constitute multidimensional symbols that each carry a large number of information bits, typically 10 to 50. Detection of these symbols involves a decision-making...

Stereo Acoustic Echo Cancellation

Invention SummaryStereophonic acoustic echo cancellers often suffer from slow convergence and large deviation of echo canceller tap weights from their true values (misalignment). Both of these happen because of significant correlations among signals in the acoustic paths. Non-linearity effects are usually introduced to reduce such correlations and thereby...
