摘要： An error rate of a TFCI of a transmission data format, and when an error rate of the TFCI becomes worse, a request to increase only the power of the TFCI is issued to the transmitter. The error rate of the TFCI is computed from the error detection result of a TrCH. Especially when the data length of the TrCH is relatively short, this method is not applied, but wasteful power consumption increases. When the data length of the TrCH is long, this method is applied to realize error rate control with the wasteful power consumption minimized.

摘要： A receiver receives data transmitted from a transmitter. The data is stored in a buffer, and a reliability value of the data is computed by a computing unit. A determining unit determines reliability of the data by comparing a reliability value of existing data in the buffer and a reliability value of the data. When the reliability value of the data is higher than a predetermined value, the existing data is combined with the data. Then, an error correcting unit performs error correcting on combined data obtained, and outputs decoded bits. If the combined data includes many errors, retransmission of the data is requested to the transmitter. When the reliability value of the data is lower than the predetermined value, retransmission of data is directly requested without combining the data with the existing data.

摘要： Disclosed herein is an error correcting apparatus for receiving a signal subjected to a repetition processing in which a part of bits of an error-correction code train are repeatedly transmitted, and decoding the received signal so as to be restored to the original data. A repetition rate calculator calculates the repetition rate of the received signal subjected to the repetition processing, a soft decision data cut-off position decision unit decides the position at which a part of the soft decision data is cut off from the soft decision data which is generated by the repetition regenerator, on the basis of the repetition rate Rr, and a bit selector cuts off the part of the soft decision data at the decided cut-off position and inputs the cut part into a soft decision error-correction decoder.
