  • Communication System, Communication Apparatus and Communication Control Method
    Publication number: 20090104927
    Abstract: A communication system that applies different modulation methods to a first data portion and a second data portion which constitute communication data, includes: a receiving strength detection unit which detects a receiving strength of the communication data; a receiving strength transmission unit transmitting the receiving strength to a transmission portion which transmits the communication data; a receiving unit which receives the transmitted receiving strength; and a transmission power control unit which controls transmission power for transmitting each of the first and second data portions based on the transmitted receiving strength.
