Abstract
An automatic transmit power control (ATPC) method and system for radio equipment of a cross polarization interference canceler system (XPIC system) wherein two orthogonally polarized waves of the same frequency channel are used independently of each other. The transmit powers of the polarized waves of the object frequency channel are simultaneously increased when a drop of the receive signal level of at least one of the two polarized waves of the object frequency channel is detected.
