WIRELESS COMMUNICATION DEVICE, WIRELESS COMMUNICATION SYSTEM, AND RECEPTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a wireless communication device preventing degradation of communication quality even in an environment having correlation to an error between reception antennas. SOLUTION: The wireless communication device includes a plurality of reception antennas for receiving a wireless signal including a pilot signal and a transmission data signal. The device includes: a pilot/data division unit 1 for dividing a received wireless signal into a pilot receiving signal and a data receiving signal for each reception antenna; a CIR/noise division unit 2 for obtaining a transmission path response and noise for each reception antenna based on the pilot receiving signal; a mutual correlation matrix calculation unit 3 for obtaining a mutual correlation matrix of noise for each reception antenna; and a spatial filter 4 for obtaining a transmission data signal for each transmission antenna based on the transmission path response, the mutual correlation matrix and the data receiving signal.
