An information radio transmission system is provided that enables provision of correct control information on the transmitting side irrespective of the error volume when an error occurs in communication data. Error volume measuring data string storage units that store an error volume measuring data string are provided in both a transmitting-side communication device that transmits data by radio transmission and a receiving-side communication device that receives data transmitted from the transmitting-side communication device. The receiving-side communication device has an error volume measuring unit that measures the error volume when transmitting data. An error volume measuring data string is added to data and the data is transmitted from the transmitting-side communication device. Having received this, in the receiving-side communication device, the error volume measuring unit compares the error volume measuring data transmitted from the transmitting-side communication device with an error volume measuring data string stored in an error volume measuring data string storage unit of the receiving-side communication device, thereby measuring the error volume.
An information radio transmission system comprising a transmitting-side communication device that transmits data by radio transmission and a receiving-side communication device that receives the data transmitted from the transmitting-side communication device, wherein each of the transmitting-side communication device and the receiving-side communication device has an error volume measuring data string storage unit that stores an error volume measuring data string, and at least one of the transmitting-side communication device and the receiving-side communication device has an error volume measuring unit that measures an error volume in data transmission, and the error volume measuring unit compares the error volume measuring data transmitted from the other device with the error volume measuring data string stored in the error volume measuring data string storage unit of the one device, thereby measuring the error volume.
An information radio transmission system comprising a transmitting-side communication device that transmits data by radio transmission and a receiving-side communication device that receives the data transmitted from the transmitting-side communication device, wherein the transmitting-side communication device has an error correcting signal controller that performs error correction coding of the transmitted data and a communication controller that transmits the error-correction-coded transmitted data as packet data, and the receiving-side communication device has an error correcting signal controller that decodes the packet data on the basis of the error correction coding of the received packet data and an error measuring unit that measures an error volume in data transmission on the basis of the number of the received packets and the number of the packets that have been successfully decoded.
An information radio transmission system comprising a transmitting-side communication device that transmits data by radio transmission and a receiving-side communication device that receives the data transmitted from the transmitting-side communication device, wherein each of the transmitting-side communication device and the receiving-side communication device has a communication controller that transmits data, and the transmitting-side communication device has a transmitted data storage unit that stores transmitted data and an error volume measuring unit that measures an error volume in data transmission, and the receiving-side communication device sends back data transmitted from the transmitting-side communication device, and the error volume measuring unit of the transmitting-side communication device measures the error volume by comparing the data stored in the transmitted data storage unit with the sent-back data.
