METHOD FOR SELECTIVE DISTRIBUTED BEAMFORMING IN TWO WAY RELAYING SYSTEM

摘要

PURPOSE: A selective dispersion beam forming method in a bidirectional relay system is provided to perform dispersive beam forming by using only partial channel information. CONSTITUTION: A beam forming weighted value vector is calculated by a Rayleigh-Ritz method. The beam forming weighted value vector maximizes system capacity of a plurality of terminals. One of weighted values, which maximize the system capacity among the beam forming weighed value vector, is selected. Beam forming is performed by using the weighted value.
