Abstract
A base station of the present invention includes: first and second antenna elements that have polarization characteristics orthogonal to each other; a first converter that converts a received signal of the first antenna element into a baseband signal; a first multiplier that weights the baseband signal converted by the first converter by multiplying a first weight coefficient; a second converter that converts a received signal of the second antenna element into a baseband signal; a second multiplier that weights the baseband signal converted by the second converter by multiplying a second weight coefficient; an adder that adds the baseband signals weighted by the first and second multipliers and outputs the sum; and, a signal processor that calculates the first and second coefficients by MMSE such that the combined polarization of the received signals of the first and second antenna elements will be orthogonal to the polarization of an interference signal.
