Patent ID: 11265056

Abstract:
A radio communication system includes a transmitting station, and at least one receiving apparatus. The transmitting station includes a plurality of modulation units configured to modulate a plurality of input data to generate first data signals in units of blocks having a predetermined data length, a subtraction unit configured to calculate, by using information acquired in advance and indicating a communication path response between the transmitting station and the receiving apparatus, information indicating directivity upon transmission of the first data signals of each of the plurality of modulation units, and predetermined information included in an additional signal to be added to a data signal, a delay wave component of the additional signal and subtract the delay wave component calculated, from each of the first data signals of the plurality of modulation units, to generate a plurality of second data signals, a beam forming unit configured to adjust, by using the information indicating directivity, power and a phase upon transmission of each of the plurality of second data signals to generate a plurality of third data signals, a plurality of adding units configured to add the additional signal to each of the plurality of third data signals to generate a plurality of fourth data signals, and a plurality of communication units configured to transmit the plurality of fourth data signals to the receiving apparatus.
