COMMUNICATION SYSTEM, COMMUNICATION APPARATUS AND COMMUNICATION CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a communication system capable of enhancing receiving-side demodulation characteristics and reducing power consumption in a transmitting-side communication apparatus.

SOLUTION: The present invention relates to a communication system in which communication data are constituted of a first data part and a second data part and modulation schemes of the data parts are different. The communication system comprises: a reception strength acquiring means for acquiring a reception strength of the communication data; a reception strength transmitting means for transmitting the reception strength to a transmission section transmitting the communication data; a reception strength receiving means for receiving the sent reception strength; and a transmission power control means for controlling transmission power for the first data part and the second data part, respectively, on the basis of the sent reception strength.
