Abstract:
1. A data transmission method for placing variable-length transmission data in each frame having a fixed time length to transmit the frame, a length of the transmission data being one of two values, X (X≠0) and 0, the data transmission method comprising the steps of: at a transmitting side, wherein at the receiving side, the step of determining and calculating determines the transmission data and the error-detecting code based on the final bit position where the length of the transmission data is X, and calculates the error-detecting code based on the determined transmission data, and wherein, at the transmitting side, the step of generating the frame data generates the frame data in which the error-detecting code is placed after the corresponding transmission data and the bits of the error-detecting code are arranged in the order that is the reverse of the order of the bits of the transmission data.
