摘要： A radio communication method for transmitting data to radio stations, wherein propagation parameters to be estimated in a receiving station are controlled, based on the data transmitting, by an array antenna comprising a plurality of antenna elements to perform data transmitting in a transmitting station. This allows channels 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.

摘要： A radio station equipped with an array antenna, when transmitting an information symbol sequence to a particular radio station, uses a plurality of vectors, which are produced based on a propagation channel characteristic established between these radio stations, to simultaneously transmit a plurality of symbol sequences, which include the information symbol sequence, by way of vector multiplexing, thereby causing the particular radio station to receive the information symbol sequence, while causing other radio stations of different propagation channels to simultaneously receive a part or all the plurality of symbol sequences. Thus, when data is transmitted to a particular radio station via a radio communication channel, the concealment of information can be secured with a high level of security.

摘要： A method for generating a transmission signal to transmit a modulated signal generated using orthogonal frequency division multiplexing, from a transmitting apparatus with a plurality of antennas, toward a plurality of terminals. The method includes assigning transmission data for the plurality of terminals to a plurality of carrier groups, each carrier group including a plurality of carriers and selecting, from the plurality of antennas, an antenna to be used for transmission toward each of the plurality of terminals. As a transmission mode for each of the plurality of carrier groups, a selection is made of one of a first transmission mode, in which one modulated signal is transmitted, and a second transmission mode in which a plurality of modulated signals are transmitted by using the selected antennas. A transmission signal is generated for transmitting the transmission data assigned to the plurality of carrier groups during an identical time period, using the selected transmission mode.
