摘要

Provided is a system in which MIMO spatial multiplexing and dual-polarization transmission is combined. By configuring the system with a simple circuit structure, a wireless communication system in which a signal dually multiplexed is demodulated with high accuracy in terms of space and polarization is provided. The wireless communication system is a MIMO communication system in which antennas are used and fixed transmission channels are set up. The wireless communication system comprises a transmitting section and a receiving section. The transmitting section performs MIMO spatial multiplexing of the signals transmitted from the transmitting antennas and dual-polarization transmission of two independent signals in the same band using the two polarized radio waves orthogonal to each other. The receiving section has an interference compensator and a MIMO signal processing circuit connected to the interference compensator. The interference compensator removes the interference component between the polarized waves of the signals received at the receiving antennas by adaptive control.The MIMO signal processing circuit demultiplexes the MIMO spatially multiplexed signal independently of the signal processing by the interference compensator.
