<p>A data transmission method, a data transmission system, a sending device and a receiving device, each of which can make it unnecessary to provide, in a variable rate data transmission, a buffer for temporarily storing a sending data in a sending side while reducing a probability of rate error detection in a receiving side. In the sending side, an error detection code of the sending data is computed for every frame, the error detection code is arranged behind the corresponding sending data, and a frame data in which a row of bits is reversed by the sending data and the error detection code is generated. In the receiving side, with respect to the received frame data, a final bit position of the frame data is assumed for every frame, the sending data and the error detection code are assumed, and the error detection code of the assumed sending data is computed. Among the final bit positions of the assumed frame data, a position where the assumed error detection code agrees with the error detection code computed on the basis of the assumed sending data is determined as the final bit position of the frame data.</p> |
