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...

Rotationally Diverse Antennas

Invention SummaryState-of-the-art wireless communication antenna systems lose significant signal strength when users move their device through a wide range of typical orientations. Rotationally diverse antennas solve this problem by improving signal strengths by 8 dB on average or 30 dB at a 90% reliability level. These benefits lead to savings in transmission...
