摘要：
There is provided a data sending apparatus comprising a detecting unit to detect a transmission channel state and a coding unit for coding input information and obtaining transmission data, wherein the coding unit changes a coding processing operation in accordance with an output of the detecting unit. There is also provided a data receiving apparatus comprising a receiving unit to receive data transmitted from a communication partner, a detecting unit to detect a transmission error rate of the reception data, and a transmitting unit to transmit the transmission error rate detected by the detecting unit to the communication partner.
