    • 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-demodulated by an FM demodulation unit; a bit conversion unit performs bit conversion according to the result of symbol decision; and a frame recovery unit deletes the redundant bit added by the redundant bit addition unit of the transmission device, from the bit string de-interleaved by a de-interleaver. Thus, it is possible to surely perform an error correction with a simple configuration even when the communication state is not in a preferable environment.
    • 提供了具有用于校正通信路径中的数据错误的功能的发送和接收设备。 在传输装置中,冗余比特加法单元将除以1比特的每个数据比特加上冗余比特; 并且交织器执行交织。 发送装置通过FM调制部发送已经进行了FM调制的信号。 在接收装置中,符号判定单元在奈奎斯特点对由FM解调单元FM解调的信号进行符号判定; 位转换单元根据符号判定结果进行位转换; 并且帧恢复单元从由解交织器解交织的位串中删除由发送设备的冗余位加法单元相加的冗余位。 因此,即使当通信状态不是优选的环境时,也可以以简单的配置可靠地进行纠错。
