PROBLEM TO BE SOLVED: To obtain a wireless information transmission system in which correct control information can be obtained on a transmission side upon the occurrence of an error in communication data regardless of the amount of the error. SOLUTION: Both a transmission side communication apparatus 100 for transmitting data by radio and a reception side communication apparatus 200 for receiving data transmitted from the transmission side communication apparatus are provided with sections 115 and 215 for each storing the data sequence for measuring the amount of an error. The reception side communication apparatus 200 is provided with a section 221 for measuring the amount of the error when the data are transmitted. The transmission side communication apparatus 100 transmits the data while adding the data sequence for measuring the amount of the error thereto. When it is received by the reception side communication apparatus 200, the error amount measuring section 221 measures the error amount by comparing the error amount measurement data transmitted from the transmission side communication apparatus 100 with the data sequence for measuring the amount of error stored in the section 215 for storing the data sequence for measuring the amount of the error of its own apparatus.
