CDMA Empfangsvorrichtung und Kommunikationssystem mit adaptiver Antenne

摘要

A CDMA adaptive antenna receiving apparatus is provided with plural receivers (3-1 to 3-M) of which each is for receiving one or more of desired signal components incoming at the same time. Each of the plural receivers (3-1 to 3-M) includes plural adaptive receiving units (6-1 to 6-L) for updating sequentially a directivity in accordance with one desired signal component. The plural adaptive receiving units (6-1 to 6-L) which are included in the same receiver (3-1 to 3-M) employ a symbol decision error of the same receiver (3-1 to 3-M) in common. Each receiver (3-1 to 3-M) further includes a means (95, 96) for detecting the incoming directions of the plural desired signal components and a means (94) for controlling directivities of the plural adaptive receiving units (6-1 to 6-L) in accordance with the incoming directions of the plural desired signal components and directivities of the plural adaptive receiving units (6-1 to 6-L).
