TRANSMISSION APPARATUS AND WIRELESS COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a transmission apparatus and a wireless communication method in which the concealment of information is secured with high security in the case of transmitting data to a particular wireless station through a wireless channel.

SOLUTION: When a wireless station 101 with an array antenna transmits an information symbol sequence to the specified wireless station 102, the transmission apparatus uses a plurality of vectors generated on the basis of propagation channel characteristics 103 between the wireless stations and transmits a plurality of symbol sequences including the information symbol sequence at the same time by means of vector multiplexing to control the particular wireless station 102 to receive the information symbol sequence, and further to control other wireless station 200 adopting a different propagation channel so as to receive a part or all of a plurality of the symbol sequences at the same time.
