发明名称 METHOD FOR CONTROLLING TRANSMISSION POWER FOR REPEATER
摘要 <P>PROBLEM TO BE SOLVED: To provide a method for controlling transmission power for a repeater capable of obtaining a greater communication line capacity by controlling transmission power of the repeater so as to approach a propagation path to a multi- path propagation path in a multi-point relay transmission system. <P>SOLUTION: The transmission power PT<SB>i</SB>of each repeater 301 is controlled to satisfy a relation of PT<SB>1</SB>G<SB>1</SB>=PT<SB>2</SB>G<SB>2</SB>=...=PTLGL, where L is the number of repeaters, PT<SB>i</SB>is the transmission power of the i-th repeater 301, and G<SB>i</SB>is a propagation power loss between the i-th repeater 301 and a receiver 102. <P>COPYRIGHT: (C)2003,JPO
