ABSTRACT:
Focused on group directivity reception with respect to a combination between an adaptive array antenna technology and an interference canceller, the present invention is intended to improve the reception characteristic and improve the system capacity by generating a reference signal from the signal after interference elimination, using a difference between the reference signal and the signal after adaptive array antenna reception as an error signal and carrying out group directivity control.
