    摘要: A method of wireless communication is disclosed, in which polarization diversity can be utilized to improve fading performance or to increase the capacity of the communication channel in a scattering environment. Complementary signal information is impressed upon, or derived from, corresponding electric and magnetic polarized field components of a transmitted or intercepted electromagnetic wave. Four, five, or even six independent signal channels can thereby be utilized for communication using a localized antenna arrangement.

    摘要: Problems of fading in a multi-path environment are ameliorated, and the presence of reflective surfaces is turned from a disadvantage to an advantage, by employing a third polarization direction that effectively creates a third communication channel. This third communication channel can be used to send more information, or to send information with enhanced spatial diversity to thereby improve the overall communication performance. A transmitted signal with three polarization directions is created with a transmitter having, illustratively, three dipole antennas that are spatially orthogonal to each other. A received signal having energy content in three polarization directions is detected by a receiver having, illustratively, three dipole antennas that are spatially orthogonal to each other.

This third communication channel can be used to send more information, or to send information with enhanced spatial diversity to thereby improve the overall communication performance. A transmitted signal with three polarization directions is created with a transmitter having, illustratively, three dipole antennas that are spatially orthogonal to each other. To take advantage of the signal with the third polarization direction, the receiver also comprises three mutually orthogonal antenna dipoles.
