ADAPTIVE BEAM FORMING METHOD IN EUROPEAN TELECOMMUNICATION STANDARD INSTITUTE SYSTEM

摘要

PURPOSE: An adaptive beam forming method in an European telecommunication standard institute system capable of quickly forming an adaptive beam of an array antenna by using a CMA and decision directed algorithm is provided. CONSTITUTION: In an adaptive beam forming method in an European telecommunication standard institute system, an additional vector of an adaptive filter for forming a beam is firstly determined in a data block of a specially physical data channel. The firstly determined additional vector of an adaptive filter is upgraded by a predetermined period. an additional vector of other adaptive filter for forming a beam is secondly determined in a pilot information, a transmission power control block, and a transmission format discriminating block of a specially physical data channel. The secondly determined additional vector of the other adaptive filter is upgraded by a predetermined period.
