Method and apparatus for performing transmission and reception simultaneously in same frequency band

摘要

There are provided a method and apparatus for transmitting and receiving signals in the same frequency band at the same time. A signal is received using a dual polarization antenna, the main axis of the polarization of the reception signal is predicted by performing adaptive polarization tracking, and polarization filtering is performed in order to remove interference. A signal is transmitted through a polarization completely orthogonal to the tracked polarization. In accordance with the present invention, in a wireless communication system, signals can be transmitted and received in the same frequency band at the same time.

1. A method of transmitting and receiving signals, comprising:
receiving a signal using a dual polarization antenna; tracking a main axis of a polarization of the reception signal by performing an adaptive polarization tracking function which tracks the main axis of the polarization of the reception signal and performing polarization filtering for removing an interference signal of the reception signal; and generating a polarization orthogonal to the main axis of the polarization of the reception signal and sending a signal through the generated polarization; wherein the receiving of the signal and the sending of the signal are performed in a same frequency band at a same time.
