IPC: H04B1/713
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a device and a method for separately extracting only the radio wave of a desired form at high speed in a real space, where various radio waves are mixed. SOLUTION: A received signal from a radio wave environment, in which radio waves of plural forms exist, is made to branch into a first and a second signals S1 and S2, then the second signal S2 is delayed just by a designated delay time and shifted just by a designated phase.

In order to control the magnitude of the output of extracted signals in the desired form, a controller 6 makes the delay time and phase charged based on the extracted signal SOUT.
