DATA COMMUNICATION CONTROL SYSTEM, TRANSMITTER, AND TRANSMITTING METHOD |
摘要 |
Data communication quality depending on the type of data to be transmitted is ensured. A coding modulation method is selected depending on the reception quality estimate informed by a portable telephone (3) and the type of data of a transmission signal D15 to be transmitted to the portable telephone (3) and used. The transmission signal D15 can be modulated and transmitted with a data communication quality predicted on the assumption that the portable telephone (3) would request it.
