COMMUNICATION APPARATUS, COMMUNICATION TERMINAL, COMMUNICATION METHOD, AND RECORDING MEDIUM HAVING COMMUNICATION PROGRAM RECORDED THEREON
Document Type and Number:
WIPO Patent Application WO/2018/061903
Kind Code:
A1
Abstract:
[Problem] To provide a communication apparatus, a communication terminal and a communication apparatus control method for enabling the prevention of a decrease in communication performance.
[Solution] A communication apparatus 600 comprises a feeding unit 610, a plurality of communication units 620, and a MIMO processing unit 630. The plurality of communication units 620 input to the feeding unit 610 analog transmission signals obtained by converting digital transmission signals inputted by the MIMO processing unit 630 into analog signals, convert analog received signals distributed and inputted by the feeding unit 610 into digital signals based on the analog received signals, and input the digital signals to the MIMO processing unit 630. The feeding unit 610 distributes the same number of analog signals based on the analog received signals as the number of the plurality of communication units 620 to the plurality of communication units 620, and distributes the same number of analog transmission signals as the number of the plurality of communication units 620 to a plurality of antenna elements in such a way that electromagnetic waves having a predetermined phase difference therebetween are radiated.
