1. A radio transmission and reception apparatus comprising:
an array antenna configured to form multiple beams having different directivities and transmit and receive signals through the multiple beams;
a digital unit configured to synthesize orthogonal polarization pairs and generate multi-beam signals for forming the multiple beams; and
a radio frequency (RF) unit configured to frequency-convert the multi-beam signals and output each of the multi-beam signals to the array antenna,
wherein the digital unit includes:
a polarization synthesizing unit configured to synthesize the orthogonal polarization pairs from heterogeneous polarization signals;
a polarization allocation unit configured to allocate the orthogonal polarization pairs to each of the multiple beams; and
a polarization allocation control unit configured to generate a polarization allocation control signal for each of the multiple beams according to a number of multiple beams and a polarization component of a reference beam and provide the polarization allocation control signal to the polarization allocation unit.
