摘要: The invention relates to the establishment of a radio link using at least two spatial modes (in other words horizontal and vertical or right left circular modes) by means corresponding antennae line three conductors use one transmission oscillator no on reception side, wherein transmitter has amplitude and/or phase frequency modulation different polarized are received processed more multipliers, mixers, comparators, power detectors.
