COMMUNICATION APPARATUS AND COMMUNICATION SYSTEM INCLUDING THE SAME, AND DUAL POLARIZATION SIGNAL TRANSMITTING AND RECEIVING METHOD OF COMMUNICATION SYSTEM

摘要

Disclosed is a communication system including a first communication apparatus and a second communication apparatus that communicate with each other through a dual polarization antenna, the system including: a first communication apparatus which calculates a co-polar ratio defined by a ratio of a first channel gain for a first polarization and a second channel gain for a second polarization; and a second communication apparatus which calculates a first rotation angle for the first polarization and a second rotation angle for the second polarization, respectively, by using the co-polar ratio transferred from the first communication apparatus, and transmits to the first communication apparatus a first rotational polarization generated by rotating the first polarization at the first rotation angle and a second rotational polarization generated by rotating the second polarization at the second rotation angle.
