    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： The present invention relates to a handover method in CDMA mobile communication. A base station and a mobile station of the same establishes synchronization after the handover by correcting a discrepancy of a frame number on the base station side to reduce the processing load of the mobile station. Further, at the same time, optimumly performing a phase correction of the frame. In particular, a mobile station MS measures a time difference □ between a frame timing in an upstream traffic channel and a frame timing in a perch channel from a second base station BS2. Further, the second base station transmits the time difference □ to a base station in communication BS1. The base station BS1 sends the time difference □ and a frame number FN1 in the upstream traffic channel in communication to the base station BS2. The base station BS2 corrects the phase of the spread code at the reception of the upstream traffic channel based on the received time difference □ of the frame timing and the notified frame number FN1.

    摘要： Disclosed are an error-detecting encoding apparatus for creating parity bits by error-detecting encoding processing, appending the parity bits to an input data string and encoding the data string, and an error-detecting decoding apparatus for detecting error using these parity bits. Data segmenting means segments an input data string, which is to undergo error-detecting encoding, into a plurality of sub-data strings, dividing means divides the segmented sub-data strings by a polynomial, which is for generating an error-detecting code, and calculates remainders, converting means applies conversion processing, which conforms to a segmentation position of the sub-data strings, to the remainders on a per-remainder basis, and combining means combines converted values, which have been obtained by the conversion processing, and outputs parity bits. An encoder appends this parity to a data string, and a decoder detects error using this parity.
