Abstract

PURPOSE:To prevent the reduction of an error correcting capacity accompanying the increase of a data quantity (frame length) by selecting an error correcting system in accordance with the data quantity (frame length). CONSTITUTION:When in a transmitting data deciding means 111, it is detected that the transmitting data to add self-station data exceed a prescribed data quantity, coding to strengthen the error correcting capacity of the transmitting data is executed by a second error correcting coding means 113 and the data are transmitted to a next station. When in a receiving data deciding means 115, it is detected that the receiving data are a second error correcting coding data, the error correcting decoding processing corresponding to this is executed by a second error correcting decoding means 117. Thus, by a first error correcting decoding means 101 and an error correcting coding means 105 and the second error correcting decoding means 117 and the error correcting coding means 113, an error correcting system is selected in accordance with the data quantity (frame length) is selected. Thus, even when the data quantity is increased, an error correcting capacity is improved.
