Abstract

PURPOSE:To avoid erroneous signal receiving, by providing a block identification bit, which is inverted at every signal discrimination period, in signal transmission where a signal block is transmitted plural times repeatedly. CONSTITUTION:A preamble is a bit for bit synchronizing, and the first block- the fourth block are signals of the same pattern consisting of a start signal and information A. In case information B of different contents is transmitted continuously, blocks are transmitted with a guard time. Further, a block identification bit is inverted successively and is inserted before each block, for example, 1 and 0 are inserted for information A and B respectively, and thus, the same information and different information are distinguished from each other even if the same signal is received twice.
