Title:
BASE STATION AND MOBILE STATION FOR MOBILE COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP3803218
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce transmission power required for realizing reliable communication by providing a delay element and a second antenna for transmitting a delay input signal independently of the transmission of an input signal by means of a first antenna.
SOLUTION: An amplifier 331 amplifies a delay signal outputted from a delay element 320 and the amplified signal is sent to an antenna 302. It is transmitted to a mobile station by radio. Namely, the delay signal is transmitted to the mobile station from the antenna 302 independently of prescribed time delay Δ after the signal is transmitted from an antenna 301. The modulation signal is also given to a delay element 32N and the delay element 32N delays the modulation signal by prescribed delay time NΔ. Then, the delayed signal is outputted. The amplifier 33N amplifies the delay signal from the delay element 32N and the amplified signal is sent to an antenna 30N and it is transmitted to the mobile station by radio.
