There are provided a transmission and reception device having a function for correcting a data error in a communication path. In the transmission device, a redundant bit addition unit adds a redundant bit to each data bit which has been divided by one bit by a division unit; and an interleaver performs interleave. The transmission device transmits a signal which has been subjected to FM modulation by an FM modulation unit. In the reception device, a symbol decision unit performs a symbol decision at a Nyquist point for a signal which has been FM-demodula...
1. A transmission device which modulates and transmits transmission data of which a level of importance has been previously determined, comprising: a division unit configured to divide (1) a high-importance data string by one bit to generate high-importance bit data each having one bit and (2) a low-importance data string into low-importance bit data each having two bits;a bit addition unit configured to add a fixed value of one bit to each one bit of the high-importance bit data, to generate two bit high-importance bit data; anda modulation unit configu...
