ADAPTIVE ANTENNA TRANSMISSION DEVICE AND ADAPTIVE ANTENNA TRANSMISSION METHOD

摘要

PROBLEM TO BE SOLVED: To reduce the influence of propagation environment estimation errors without throughput reduction. SOLUTION: M pieces of reception signals transmitted from a terminal station and received by M pieces of antenna elements are taken as input signals. These M pieces of signals are converted in accordance with a formula (1), and a directivity controller controls the directivity on the basis of r1to rMand r'1to r'M. COPYRIGHT: (C)2005,JPO&NCIPI
