    摘要: The disclosed invention relates to a MIMO (multiple input, multiple output) wideband transceiver. In some cases, the MIMO wideband transceiver comprises a signal processor that outputs or receives a plurality of distinguishable data streams. A first data stream is provided to a first antenna port connected to a plurality of wideband antennas, while a second data stream is provided to a second antenna port connected to a wideband antenna. A spatial filter element configured to assign antenna weights to the plurality of wideband antennas, which cause the wideband antennas to operate in a manner that attenuates wireless signals, at a frequency range at which the wideband transmit wideband radiate, in the direction of the wideband antenna without attenuating the wireless signals in other directions. By attenuating signals extending between the plurality of wideband antennas and the wideband antenna, wideband decoupling between first and second antenna ports is achieved.

    摘要: The present invention refers to a protective colloid for the aqueous emulsion polymerisation of vinyl esters consisting of hydroxypropylguar having a degree of molar substitution from 1 to 4, and a 2% viscosity ranging from 1,000 to 25,000 mPa*s; the aqueous emulsions of polyvinyl esters containing such protective colloid are characterised by the fact the they exhibit improved mechanical stability, high stability to freeze and heath, and were found to be particularly useful for the preparation of paints having marked resistance to water.

    摘要: Disclosed herein are techniques, systems, and methods relating to minimizing mutual coupling between a first antenna and a second antenna. In one implementation, a plurality of antennas and at least one tuning module are provided. A control module may be coupled to the tuning module. The control module may be configured to control the at least one tuning module to alter a phase and an amplitude of a control signal communicated to at least one of the plurality of antennas to reduce mutual coupling between the plurality of antennas.
