摘要： In a mobile telephone terminal at the transmitting end, voice data to be transmitted are sequentially inputted, and it is determined whether the inputted voice data are silent. The voice data regarded as silent voice are replaced by group numbers, while the voice data indicative of sonant voice as well as the group numbers as replaced are transmitted by wireless. On the other hand, in a mobile telephone terminal at the receiving end, the signals transmitted by wireless are received, and the voice data and group numbers of the received signals are discriminated. The voice data are reproduced as they are, while the group numbers are reproduced as silent, and further processings based on the group numbers are executed. This allows predetermined data to be repetitively transmitted with a high efficiency without degrading communication quality very much. This also facilitates a follow-up participation in a group call.

摘要： A soft decision device and method for obtaining a soft decision value as a value expressing a probability as near the actual probability as possible by simple processing. The soft decision device and method are used to output a soft decision value for each bit of each symbol used for decoding the each symbol as a value corresponding to the function value obtained by applying a predetermined function for each bit to the sampled value of the each symbol according to the demodulated signal such that the probability distribution of the sampled value in each symbol point is the Gauss distribution. The function for each bit is approximated to a curve expressing the probability that each bit is 1 or 0 for the sampled value of each symbol of the demodulated signal and defined by using a quadratic function.

摘要： 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 judgment unit performs a symbol judgment 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 judgment; and a frame restoration 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.
