CDMA multiuser receiver featuring a combination of array antenna and multiuser interference cancellers

摘要

In order to effectively reduce a size of a CDMA multiuser receiver while maintaining an excellent interference cancellation, an array antenna is combined with a multiuser receiver. The multiuser receiver includes signal processing means which is supplied with incoming signals received at the array antenna. The signal processing means estimates interfering signals with respect to each of the antenna elements and with respect to each of simultaneously accessing users.
