Abstract

PURPOSE:To improve an information transmission efficiency by providing a sub- channel multiplexed in the frequency division system on the same line or a sub- channel using another line besides the main channel, which transmits information words, and using this sub-channel for synchronizing signal transmission. CONSTITUTION:Parallel-series conversion circuit 2 where input information D1 to D16 from a vehicle sensor are inputted and a main channel which has modulator 3, where the output of circuit 2 is inputted to transmit prescribed information words to transmission path 7, inserted are provided, and further, a sub-channel which has code generation circuit 5, which is connected to clock signal line 4, and modulator 6, which subjects prescribed bits to multiple modulation, inserted is provided besides the main channel. Then, the sub-channel is used as a channel to transmit synchronizing signals dependent upon plural code constitutions generated by clock signals of circuit 2, and the timing of synchronizing signals is adjusted to be synchronized with the receiving pattern of the main channel.
