Title:

TRANSMITTING APPARATUS, RECEIVING APPARATUS, RADIO COMMUNICATION METHOD, AND RADIO COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2004/028031

Kind Code:

A1

Abstract:

A radio communication method for transmitting data to radio stations, wherein propagation parameters to be estimated in a receiving station (202) are controlled, based on the data to be transmitted, by an array antenna comprising a plurality of antenna elements (203a,203b) to perform data transmission in a transmitting station (201). This allows channels (205a,205b) characterized by the propagation parameters to be shared only by particular radio stations, and signals are superimposed on the propagation parameters, thereby realizing radio access in which a high security is retained.
