WIRELESS BASE STATION DEVICE AND WIRELESS COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To increase the system capacity by combining an interference canceller and an adaptive array antenna AAA so as to enhance the reception characteristic of an incoming channel signal without increasing the scale of hardware. SOLUTION: With respect to the combination of an adaptive array antenna technology and an interference canceller, taking notice of group directivity reception, a reference signal is generated from a signal after elimination of the interference, a difference between the reference signal and a signal after the reception of the adaptive array antenna is used for an error signal to conduct group directivity control thereby the reception characteristic is enhanced and the system capacity is increased.
